Peter Kreeft: Luther Was Simply Right About Faith Alone?

I've come across this quote from Roman Catholic author Peter Kreeft a number of times over the years:

"How do I resolve the Reformation? ​ Is it faith alone that justifies, or is it faith and works?​ Very simple. No tricks.​ On this issue I believe Luther was simply right; and this issue is absolutely crucial. ​ As a Catholic I feel guilt for the tragedy of Christian disunity because the church in the fifteenth and sixteenth centuries was failing to preach the gospel.​ Whatever theological mistakes Luther made, whatever indispensable truths about the Church he denied, here is an indispensable truth he affirmed — indispensable to union between all sinners and God and union between God’s separated Catholic and Protestant children."​

It is interesting to find a Roman Catholic author saying anything nice about either the Reformation or Martin Luther... but the quote just seems too good to be true. Based on the context below, I would caution Protestants from utilizing this quote from Peter Kreeft because... it is too good to be true. There are indeed "tricks" going on.

Context
The fourth issue is the most crucial of all. It is the issue that sparked the Reformation, and it is the issue that must spark reunion too. It is, of course, the issue of faith, of faith and works, of justification by faith. 
This is the root issue because the essence of the gospel is at stake here. How do I get right with God? This was the issue of the first century church at Galatia, a church Protestants see as making the same essential mistake as the Catholics-preaching the gospel of good works. Protestants dare not compromise on this issue or they would be turning to what Paul calls "another gospel". Thus his harsh words to the Galatians, the only church for which he has not one word of praise: 
"I am astonished that you are so quickly deserting him who called you in the grace of Christ and turning to a different gospel-not that there is another gospel, but there are some who trouble you and want to pervert the gospel of Christ. But even if we, or an angel from heaven, should preach to you a gospel contrary to that which we preached to you, let him be accursed." 
How do I resolve the Reformation? Is it faith alone that justifies, or is it faith and good works? Very simple. No tricks. On this issue I believe Luther was simply right; and this issue is absolutely crucial. As a Catholic I feel guilt for the tragedy of Christian disunity because the church in the fifteenth and sixteenth centuries was failing to preach the gospel. Whatever theological mistakes Luther made, whatever indispensable truths about the Church he denied, here is an indispensable truth he affirmed-indispensable to union between all sinners and God and to union between God's separated Catholic and Protestant children. 
Much of the Catholic Church has not yet caught up with Luther; and, for that matter, much of Protestantism has regressed from him. The churches are often found preaching one of two "other gospels": the gospel of old-fashioned legalism or the gospel of new-fangled humanism. The first means making points with God and earning your way into heaven, the second means being nice to everybody so that God will be nice to you. The churches, Protestant and Catholic, may also preach the true Christian gospel, but not often enough and not clearly enough and often watered down and mixed with one of these two other gospels. And the trouble with "other gospels" is simply that they are not true: they don't work, they don't unite man with God, they don't justify.
No failing could be more serious; but on the Catholic side, as distinct from the liberal Protestant side, it is a failing in practice, not doctrine. When this happens, the Catholic Church fails to preach its own gospel. It is sitting on a dynamite keg and watering the fuse; it is keeping a million dollar bank account and drawing out only pennies. Catholicism as well as Protestantism affirms the utterly free, gratuitous gift of forgiving grace in Christ, free for the taking, which taking is faith. Good works can be only the fruit of faith, flowing freely as a response to the new life within, not laboriously, to buy into heaven. 
But there are two important verbal misunderstandings in the Reformation controversy over faith and works. First, when the Council of Trent affirmed, contrary to Luther, that good works contribute to salvation, it meant by salvation not just getting to heaven but the whole process of being transformed and becoming incorporated into the life of God. In other words, salvation meant not just justification but sanctification as well; and it was quite correct to say that both faith and works contribute to sanctification, thus to salvation. 
Second, Catholic and Protestant theologians mean different things by the word faith. Protestants usually follow biblical usage: faith means saving faith, the heart or will accepting Christ. Catholics usually follow a more technical philosophical and theological usage: faith means the act of the mind, prompted by the will, which accepts Christ's teachings as true. In Protestant language, faith means heart faith, or whole-person faith; in Catholic language, faith means mind faith. Thus, Catholic theologians are right to deny justification by faith alone in that sense (which of course was not Luther's sense). For "the devils also believe, and tremble." in this narrower sense faith can exist without the works of love; as James writes, "Faith without works is dead." In the larger sense, faith cannot exist without works, for it includes works as a plant includes its own blossoms.

Conclusion
I see only one positive aspects of this quote: Kreeft espouses 20th Century ecumenism embracing (a position taken by a number of Roman Catholic scholars) not placing the entirety of blame for the Reformation on Luther. Rome's laymen often say the opposite: Luther was completely responsible for everything. Other than that, I would caution Protestants from utilizing this quote from Peter Kreeft. Here are my reasons. 

1. Peter Kreft is putting forth theological confusion by inferring the Protestant Reformers had the same Gospel, but Rome's error was that they were not preaching this agreed upon Gospel in the fifteenth and sixteenth centuries. I've mentioned a number of times on this blog over the years, Rome did not have an official dogmatic pronouncement on justification previous to the Council of Trent: 
Existing side by side in pre-Reformation theology were several ways of interpreting the righteousness of God and the act of justification. They ranged from strongly moralistic views that seemed to equate justification with moral renewal to ultra-forensic views, which saw justification as a 'nude imputation' that seemed possible apart from Christ, by an arbitrary decree of God. Between these extremes were many combinations; and though certain views predominated in late nominalism, it is not possible even there to speak of a single doctrine of justification. [Jaraslov Pelikan, Obedient Rebels: Catholic Substance and Protestant Principle in Luther’s Reformation [New York: Harper and Row, 1964, 51-52].
All the more tragic, therefore, was the Roman reaction on the front which was most important to the reformers, the message and teaching of the church. This had to be reformed according to the word of God; unless it was, no moral improvement would be able to alter the basic problem. Rome’s reactions were the doctrinal decrees of the Council of Trent and the Roman Catechism based upon those decrees. In these decrees, the Council of Trent selected and elevated to official status the notion of justification by faith plus works, which was only one of the doctrines of justification in the medieval theologians and ancient fathers. When the reformers attacked this notion in the name of the doctrine of justification by faith alone—a doctrine also attested to by some medieval theologians and ancient fathers—Rome reacted by canonizing one trend in preference to all the others. What had previously been permitted (justification by faith and works), now became required. What had previously been permitted also (justification by faith alone), now became forbidden. In condemning the Protestant Reformation, the Council of Trent condemned part of its own catholic tradition [Jaroslav Pelikan, The Riddle of Roman Catholicism (New York: Abingdon Press, 1959), pp. 51-52].
2. Kreeft puts forth an ecumenical hodge podge statement attempting to portray an agreement between Rome and Luther: "Catholicism as well as Protestantism affirms the utterly free, gratuitous gift of forgiving grace in Christ, free for the taking, which taking is faith. Good works can be only the fruit of faith, flowing freely as a response to the new life within, not laboriously, to buy into heaven." What exactly is Kreeft saying?  Further down he clarifies he's putting forth pure Romanism: 
First, when the Council of Trent affirmed, contrary to Luther, that good works contribute to salvation, it meant by salvation not just getting to heaven but the whole process of being transformed and becoming incorporated into the life of God. In other words, salvation meant not just justification but sanctification as well; and it was quite correct to say that both faith and works contribute to sanctification, thus to salvation.
This is not Reformation theology! In Luther's thought, being justified before God was on the basis of a perfect righteousness (Christ's) that is not one's own. One is not sanctified to eventual justification finally completed after being purified in purgatory. 

3. Kreeft then launches into a discussion of the term "faith" positing that Protestants use the word as defined by the Bible, while Roman Catholics use the word defined by philosophy and theology! I can only speculate he added "theology" as some sort of jab at Protestants clinging to Sola Scriptura while Rome's defenders have more than one infallible authority to "theologize" from (Tradition and the Magisterium). 

4. It's true that Trent says that faith is needed to be justified, but Trent did not affirm that faith alone justifies. The Protestant Reformers held that faith is placed in the works of another: Christ's works, and only those works serve as a basis for a right standing before God. In Protestant theology, the fruit of works are a response of gratitude that one has been justified. One's works are not done in the process of being eventually justified. 

5. Kreeft says "Good works can be only the fruit of faith, flowing freely as a response to the new life within." That seems "Protestant" enough until one reads his eventual clarification. He mentions James writing "faith without works is dead" and adds, "faith cannot exist without works, for it includes works as a plant includes its own blossoms." Using his own analogy, in Roman Catholic theology, one is a plant growing into an eventual justified blossom! 

Addendum
Here's an interesting YouTube link in which Scott Hahn wrote Peter Kreeft about this very issue. In the letter, Kreeft says (at around 1:40) that he "confused the truth in Luther, sola gratia, with the untruth, sola fide."

"Tradition" reposted


Tradition

Originally written in April of 2016.  Reposting now with an important link to Scott Hahn's testimony restored.



μάτην δὲ σέβονταί με διδάσκοντες διδασκαλίας ἐντάλματα ἀνθρώπων

 "And in vain do they worship Me, teaching as doctrine the commandments of men" Mark 7:7


  

ἀφέντες τὴν ἐντολὴν τοῦ θεοῦ κρατεῖτε τὴν παράδοσιν τῶν ἀνθρώπων

 "leaving/abandoning the commandment of God, you are holding onto the traditions of men"

Mark 7:8

 The Aorist participle of "leaving"/ "neglecting" / "abandoning" (aphentes- αφεντες, from aphiaemi αφιημι ) seems to be contrasted with the present active verb of "holding onto" ( κρατειτε )- because they are so focused on teaching as doctrine, the commandments of men (verse 7), or they are so focused on holding onto their own man-made traditions (8b), it caused them to neglect, abandon, leave the commandment of God (the word of God, the Scriptures).  Or, it could be an adverbial participle of means or manner, modifying the way they are holding onto the traditions of man - "by abandoning" or "by neglecting" . . . "you are holding onto". Or it could be a causal participle, "because you neglected the commandment of God, you are holding onto the traditions of man".  Or it could be a temporal participle:  "while neglecting the commandment of God" or "after neglecting the commandment of God".   Any of these three fit the context.  This is exactly what the church started doing little by little in history.

 It is interesting to me that the word for "leaving" ("abandoning" or "neglecting") is also the word used in Revelation 2:4 - "you have left your first love"
ἀλλὰ ἔχω κατὰ σοῦ ὅτι τὴν ἀγάπην σου τὴν πρώτην ἀφῆκες "But I have this against you, that you have left your first love"

 and
Matthew 23:23 - "you have neglected the weightier provisions of the law . . . "

Dr. Plummer pointed out in the video that this word, aphiaemi / αφιημι - has a wide range of meaning, many times, in context, it means "to forgive" sins, and other times "to divorce", but you can see the idea of "leaving", "abandoning", "neglecting", "forsaking" in the basic concept.

This is what the Roman Catholic Church did in history, by clinging to man-man traditions and holding onto them, they neglected and abandoned important doctrines such as justification by faith alone; and emphasized Mary too much and exalted her too much, and created doctrines such as Purgatory; and said that bread and wine turns into the body and blood of Jesus by the words of a RC priest. They emphasized and clung to external works and relics and penances and pilgrimages, and clinging to those things caused them to not see the main issues. Justification by faith alone was there all along in the Bible, and hinted at by some early church fathers, but it was left behind and neglected by their emphasis on external works, focus on non-Biblical things about Mary, statues, priests, penances, relics, etc.

Some Roman Catholics like to say that Protestants treat "tradition as a dirty word" or "always negative" and some (far too many) Evangelicals have done that; but that should not be and everyone should be able to handle the passages that speak of "traditions" in a positive way, since they are the true apostolic traditions.

 2 Thessalonians 2:15

"But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you rom the beginning for salvation through sanctification by the Spirit and faith in the truth. 14 It was for this He called you through our gospel, that you may gain the glory of our Lord Jesus Christ. 15 So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter from us." 2 Thessalonians 2:13-15
I have never understood why former Evangelicals who have converted to Rome say that they could not explain or handle verse 15.  As in the following in Scott Hahn's testimony of how he just melted into goo when the question was posed to him about 2 Thessalonians 2:15:    (to see where this is, scroll down to the paragraph with the heading "Teacher at a Presbyterian Seminary")  ( As I recall, a lot of the Surprised by Truth (edited by Patrick Madrid) testimonies also told of how they were unprepared to deal with that verse.)


Then he turned the tables on me. The students were supposed to ask him a question or two. He said, "Can I first ask you a question, Professor Hahn? You know how Luther really had two slogans, not just sola fide, but the second slogan he used to revolt against Rome was sola Scriptura, the Bible alone. My question is, 'Where does the Bible teach that?'"
I looked at him with a blank stare. I could feel sweat coming to my forehead. I used to take pride in asking my professors the most stumping questions, but I never heard this one before. And so I heard myself say words that I had sworn I'd never speak; I said, "John, what a dumb question." He was not intimidated. He look at me and said, "Give me a dumb answer." I said, "All right, I'll try." I just began to wing it. I said, "Well, Timothy 3:16 is the key: 'All Scripture is inspired of God and profitable for correction, for training and righteousness, for reproof that the man of God may be completely equipped for every good work....'" He said, "Wait a second, that only says that Scripture is inspired and profitable; it doesn't say ONLY Scripture is inspired or even better, only Scripture's profitable for those things. We need other things like prayer," and then he said, "What about 2 Thessalonians 2:15?" I said, "What's that again?" He said, "Well, there Paul tells the Thessalonians that they have to hold fast, they have to cling to the traditions that Paul has taught them either in writing or by word of mouth." Whoa! I wasn't ready. I said, "Well, let's move on with the questions and answers; I'll deal with this next week. Let's go on."
I don't think they realized the panic I was in. When I drove home that night, I was just staring up to the heavens asking God, why have I never heard that question? Why have I never found an answer? 

Aside for failing to distinguish between 1 or 2 Timothy, it is amazing to me, that he could not handle this, when one looks at the context of verses 13 and 14; and the date and historical background of when 2 Thessalonians was written.

1.  The historical context of when the Thessalonians epistles were written.  (50-52 AD) Obviously, at this point, the only other letters that Paul has written are Galatians (48-49 AD) and 1 Thessalonians (50 AD), so it seems obvious that the apostle was preaching and teaching content that will be later included in letters such as Romans, 1 & 2 Corinthians, Ephesians, Philippians, Colossians, 1-2 Timothy, etc. There is no evidence at all that the apostle taught anything that Roman Catholics claim he may have, RC traditions like Mary as a perpetual virgin, or purgatory, or priests as a NT office, or indulgences, or the Papacy, or the Immaculate Conception of Mary, or Transubstantiation, external penances, relics, praying to Mary. No; it is obvious that Paul means was essential doctrine that will be later in the rest of Scripture. There is no evidence that the apostles taught any of those things that Roman Catholics developed centuries later. They read their own traditions back into the word "tradition".

2.  The context of the verse within the paragraph.  Verse 14 identifies the traditions of verse 15 as the gospel ("our gospel"), and verse 13 shows the doctrines of election, salvation, "sanctification by the Spirit", "faith in the truth" as part of the gospel.

2 Thessalonians 3:6
This verse points to the context of the teachings in verses 7-14, and what Paul already taught them in 1 Thessalonians 4:11-12 and 5:14.

1 Corinthians 11:2 - same principle here; 1 Corinthians is early also, around 55 AD, so the same principle goes, and by the rest of the content of the whole letter of 1 Corinthians, especially in the rest of chapter 11 and 15, but not excluding any of the letter.   Paul considers his teaching and letters as spiritual truths (1 Corinthians 2:12-13) that he is passing on/delivering/handing over = "traditioning" to them. Since they have written questions about issues that were raised after he taught them (see 1 Cor. 7:1); and he will also write another letter to them (2 Corinthians, which may have as part of it embedded in it, the same content as the "painful letter" about church discipline mentioned in 2 Corinthians 7:8 and 7:12 and possibly with 2 Corinthians 2:2, or it may also refer to 1 Corinthians 5 about church disciple), (or it may be a lost letter); it seems obvious the traditions are basic gospel issues and teachings.  These essential teachings will all be included in writing, that will eventually all be finished by 96 AD.  All Scripture is written down by either 70 AD or 96 AD.  Also, the context is on the content of what he writes to them in chapter 11.

1 Corinthians 15:3 has the verbal form of "tradition", "to deliver", which is also used in Jude 3 - "the faith once for all delivered to the saints". It seems obvious that the context of 1 Corinthians 15 is about gospel essentials (which agrees with 2 Thessalonians 2:13-15, and that Jude 3 shows that all the truths of the faith necessary for the saints was already delivered once for all. This, along with Jesus' promise that when the Holy Spirit comes, He would lead the apostles into all the truth (John 16:12-13) and bring to their remembrance everything (John 14:26); it is reasonable to assume that all the truths needed would be written down.

 It seems to me easy to see, when 2 Timothy 3:16 says that "all Scripture is God-breathed", that whatever is God-breathed or inspired is revelation from God, and when that revelation is written Scripture; and since it is God-breathed, is also "canon", since "canon" meant "principle", "law", "criterion", "standard", before it meant "a specific list of books" recognized / discerned as "God-breathed".
As Dr. White has said many times, and James Swan in an article below, 

"The canon list is not revelation, it's an artifact of revelation."  

This means it is physical evidence and a result of revelation, a proof that revelation happened in history, since all 27 books were first individual scrolls in the first century, and each one was God-breathed Scripture, the list is merely the "footprint" or evidence or product of them all together. 
 Scripture is sufficient to equip the man of God in the church for "every good work" (2 Timothy 3:17; verse 17 is important to include), for ministry and teaching and counseling people (rebuking, correcting, training). Paul assumes that the "man of God" is a man like Timothy who has already been qualified to be an elder/pastor/teacher/overseer in the local church (see the whole letters of 1 and 2 Timothy, and Titus).  Things like the local church (1 Timothy 3:14-16), teaching, being an elder/pastor/teacher, a man of God, a man of prayer, qualified, are assumed in the whole context of the whole letters of 1 and 2 Timothy and Titus.  The fact that Paul quoted gospels with law in 1 Timothy 5:18 as Scripture, and that Peter wrote that all of Paul's letters are Scripture (2 Peter 3:16), along with the "once for all" of Jude 3, rounds things out as logical and reasonable to assume that all things that were needed for the church were written down in Scripture.   2 Timothy 3:15 is about the OT only, but 2 Timothy 3:16 expands it to "all Scripture", including by principle, all of the NT books, even those written in the future.

Colossians 2:8 and 2:20-23 are also negative on man-made traditions.  They also point to man-made traditions,  (as Mark 7 and Matthew 15 do), philosophy, and the "elementary principles of this world" (see with Galatians 4:9-11) - these things seem to point the things that Roman Catholicism emphasizes - external rituals and laws, asceticism, rites and things that humans can do to make themselves feel religious - like visiting graves and praying to the dead, kissing relics, and the legalisms of adding things to faith as being necessary to do in order to merit finally that one may be justified before God in the future.

Those gospel essentials or essential doctrines are what Irenaeus (180-200 AD), Tertullian (190-220 AD), Origen (250 AD), and Athanasius (297-373 AD) refer to when they explain what "the tradition of the apostles" or "the faith" or "the preaching" is to their readers in the centuries that follow.  When they explicate what the tradition is, it never includes any of the things that Roman Catholics read back into it.  They are the same basic content as the early creeds, such as the Apostles Creed and the Nicean Creed.  More on that later, Lord willing.

See Irenaeus, Against Heresies, 1:10:1 to 1:11:1
and 1:22:1

The Real Reason Why Martin Luther Rejected the Book of James?

Here's a statement evaluating Martin Luther's opinion of the Epistle of James.

Luther strongly repudiated the Epistle as "a letter of straw", and "unworthy of the apostolic Spirit", and this solely for dogmatic reasons, and owing to his preconceived notions, for the epistle refutes his heretical doctrine that Faith alone is necessary for salvation.

 Soley for dogmatic reasons? As I've looked at this over the years, it's more complicated than that. There's actually contradicting evidence on Luther's opinion of the Epistle of James and exactly what his rejection entirely entails. Let's take a look at these charges and see if the real reason (or reasons) Luther rejected James can be determined. 

Documentation
I came by the statement above on a website dedicated to early Christian writings. Searching for the author, the webpage cited: "Camerlynck, A. "Epistle of James." Early Christian Writings. 2023. 22 Jan. 2023."  Doing a search for "Camerlynck, A," I discovered this webpage was a complete cut-and paste from the old Catholic EncyclopediaAchilles Camerlynck was a well-educated Roman Catholic scholar from long ago. The old Catholic Encyclopedia is generally not favorable to Luther, so it makes sense that multiple shots are taken at Luther by Camerlynck 

The early Christian Writings website appears to be selling CD-ROM's (remember those?) of the entire content of the website (I'm not sure what the legality of that is... selling someone else's work?). Back in 2015, the owner of the site gave a brief overview of who he was: a young man with Roman Catholic roots that's become some sort of agnostic (as of 2015). Where he is now on his spiritual journey, I didn't spend time to discover. His blog entries stop December 2015. From a cursory search, he appears to have fallen off the cyber-radar in 2015. 

Letter of Straw? Epistle of Straw?
Luther's famous statement is "Saint James’ epistle is really an epistle of straw" compared to John's gospel and epistles, Paul's epistles, and 1 Peter, and, further, that James "has nothing of the nature of the gospel about it" (LW 35:362). The  "epistle of straw" line comes from Luther's Preface to the New Testament, originally penned in 1522.  These are negative comments. 

Back in 2004, I addressed the "epistle of straw" comment in Luther's View of the Canon of Scripture (on the now defunct NTRmin.org website). In 2007, I put up a short article on aomin.org: Six Points On Luther's Epistle of Straw. Now years later, there's nothing significant to add beyond repeating this pertinent fact:  The "epistle of straw" comment was deleted by Luther himself. He eventually dropped this comment along with the entire paragraph that placed value judgments on particular biblical books (see LW 35:361-362, particularly the footnotes, and also fn. 5 on p. 358).  The editors of Luther's Works include all the deleted text, using brackets [ ] to delineate what was dropped from the final text. The older Philadelphia edition does the same thing. I suspect they simply intended to be transparent and scholarly (presenting a type of critical text). What the final product though practically does is insert back into the text what Luther wanted edited out!  

Why did Luther delete his text? The editors of LW offer this reason: they suggest Luther's early biblical prefaces had a polemic bent directed toward his opponents: 
Divergences from the original 1522 text were due primarily to Luther’s desire to accommodate the text of the New Testament prefaces to that of the Old Testament prefaces with which they were—in the 1534 complete Bible—to appear for the first time, rather than to criticism on the part of Emser or other opponents (LW 35:357, fn 5).
It would be interesting to see which of Luther's contemporary opponents criticized Luther's view of James, especially those early on in the 1520's. In 1530, the Roman Catholic respected theologian Johann Eck included it against Luther:
106 Many, with much probability, have asserted that this epistle was not written by the apostle James, and that it is not worthy of an apostolic spirit (Luther).
 After Luther's death, his archrival Cochlaeus wrote,
For Luther seemed to the best people to have proceeded too maliciously against the Sacred Scripture of the New Testament; since he had, with an audacious censorship, rejected the Letter to the Hebrews, the Letter of James, the Letter of Jude, and the Apocalypse of John from the canon of the New Testament. He defamed these books openly, with savage falsehoods, in his prefaces.
Luther saw fit to delete the comment. Subsequent citations of this quote should at least mention his deletion. The "epistle of straw" comment is cited by those favorable and unfavorable to Luther. I suspect many of those not hostile to him citing it often don't know about the deletion and that Luther did not intend the statement to be part of his enduring legacy. For those who cite it against him, the deletion probably doesn't matter anyway. They will find a way to spin the comment to use against him. 

Unworthy of the Apostolic Spirit?
The basic thrust of "unworthy of the apostolic spirit" is that Luther did not believe the Epistle of James was written by an apostle or eyewitness of the life and ministry of Jesus Christ. He argued at times that James was a second-generation Christian. Camerlynck probably took the phrase he used from Luther's 1520 treatise, The Babylonian Captivity of the Church. In commenting on the Roman Catholic sacrament of extreme unction, Luther writes: 
But I say: If ever folly has been uttered, it has been uttered especially on this subject: I will say nothing of the fact that many assert with much probability that this epistle is not by James the apostle, and that it is not worthy of an apostolic spirit; although, whoever was its author, it has come to be regarded as authoritative. But even if the apostle James did write it, I still would say, that no apostle has the right on his own authority to institute a sacrament, that is, to give a divine promise with a sign attached. For this belongs to Christ alone (LW 36:118).

Original text: Ego autem dico: si uspiam delyratum est, hoc loco praecipue delyratum est. Omitto enim, quod hanc Epistolam non esse Apostoli Iacobi nec apostolico spiritu dignam multi valde probabiliter asserant, licet consuetudine autoritatem, cuiuscunque sit, obtinuerit. Tamen si etiam esset Apostoli Iacobi, dicerem, non licere Apostolum sua autoritate sacramentum instituere, id est, divinam promissionem cum adiuncto signo dare. Hoc enim ad Christum solum pertinebat (WA 6:568). 

A blatant thing to note here is that there's nothing in the context about faith alone. Luther is expressing doubts about the authorship of James in regard to extreme unction.  Here Luther presents two options but appears to favor the Epistle of James as not apostolic... though grants the possibility of it being apostolic. For Luther, the epistle of James may have been written by a later Christian, therefore not an apostle or eyewitness of the risen Christ, therefore not canonical. 

Just a year earlier (1519), Luther wrote the following, (and this may be his earliest criticism of James):

For although it is argued from the epistle of the Apostle James that ‘faith without works is dead,’ the style of that epistle is far inferior to the Apostolic majesty of St. Paul, and should in no way be compared with him. Paul speaks of living faith, for a faith that is dead is not faith but opinion. Yet you see theologians who hold on to this one authority and care nothing at all that the rest of Scripture teaches faith without works. That’s how these fellows do it. They rip out one little phrase from a text and set it up against all of Scripture (Resolutiones Lutherianae super propositionibus suis Lipsiae disputatis, English translation by Jason D. Lane).
Original text: Quod autem Iacobi Apostoli epistola inducitur ‘Fides sine operibus mortua est’, primum stilus epistolae illius longe est infra Apostolicam maiestatem nec cum Paulino ullo modo comparandus, deinde de fide viva loquitur Paulus. Nam fides mortua non est fides, sed opinio. At vide theologos, hanc unam autoritatem mordicus tenent, nihil prorsus curantes, quod tota alia scriptura fidem sine operibus commendet: hic enim mos eorum est, una abrepta oratiuncula textus contra totam scripturam cornua erigere] (WA 2:425).
Here, faith alone is in view. Luther appears to accept James as an authority, but of lesser authority than Paul. Luther says James lacks "Apostolic majesty," which echos "apostolic spirit," therefore questioning apostolic pedigree (and therefore, canonicity). Luther's emphasis is on those who use James as a prooftext to refute "the rest of scripture." Luther accuses his detractors of misusing James: "They rip out one little phrase from a text and set it up against all of Scripture." Luther explains what Paul means but does not overtly explain what James meant.
    
Then in his 1522 Preface to James, Luther reiterates that James was written by a second-generation Christian, 
...[H]e throws things together so chaotically that it seems to me he must have been some good, pious man, who took a few sayings from the disciples of the apostles and thus tossed them off on paper. Or it may perhaps have been written by someone on the basis of his preaching [LW 35: 396-397].

Original text: Aber diser Jacobus thutt nicht mehr, denn treybt zu dem gesetz vnd seynen wercken, vnd wirfft so unordig eyns vns ander, das mich dunckt, es sey irgent eyn gut frum man gewesen, der ettlich spruch von der Aposteln Jungern gefasset, vund also auffs papyr geworffen hat, oder ist villeicht aus seyner predigt von eynem andern beschriebon (WA Db 7:386). 

Moreover he cites the sayings of St. Peter [in 5:20]: “Love covers a multitude of sins” [1 Pet. 4:8], and again [in 4:10], “Humble yourselves under the hand of God” [1 Pet. 5:6]; also the saying of St. Paul in Galatians 5[:17], “The Spirit lusteth against envy.” And yet, in point of time, St. James was put to death by Herod [Acts 12:2] in Jerusalem, before St. Peter. So it seems that [this author] came long after St. Peter and St. Paul (LW 35:397).

Original text: Uber das, furet er die spruch Sanct Petri. Die liebe bedeckt der sund menge, Jtem demutiget euch vnter die hand Gottis, Jtem Sanct Paulus spruch Gal. 5. den Geyst gelust wider den hass. So doch Sanct Jacobus zeytlich von Herodes zu Jerusalem, fur S. Peter todtet war, das woll scheynet, wie er lengst noch S. Peter vnd Paul gewesen sey (WA Db 7:386). 

When challenged that the Epistle of James stood against justification by faith alone, in 1543 Luther stated:

The authority of this [James] is not so great that (it detracts from the divine promise [or that] on its account one should abandon the doctrine of faith and depart from the authority of the rest of the apostles and all of Scripture (LW 73:349-350). 

Original text: Non est tanta eius autoritas, ut propterea doctrina fidei relinquatur et discedatur ab autoritate reliquorum apostolorum et totius scripturae (WA 39.2: 219).

Luther is recorded in a 1542 Table Talk utterance saying,

We should throw the Epistle of James out of this school, for it doesn’t amount to much. It contains not a syllable about Christ. Not once does it mention Christ, except at the beginning [Jas. 1:1; 2:1]. I maintain that some Jew wrote it who probably heard about Christian people but never encountered any. Since he heard that Christians place great weight on faith in Christ, he thought, ‘Wait a moment! I’ll oppose them and urge works alone.' This he did. He wrote not a word about the suffering and resurrection of Christ, although this is what all the apostles preached about. Besides, there’s no order or method in the epistle. Now he discusses clothing and then he writes about wrath and is constantly shifting from one to the other. He presents a comparison: ‘As the body apart from the spirit is dead, so faith apart from works is dead’ [Jas. 2:26]. O Mary, mother of God! What a terrible comparison that is! James compares faith with the body when he should rather have compared faith with the soul! The ancients recognized this, too, and therefore they didn’t acknowledge this letter as one of the catholic epistles.” (LW 54:424).

Original text:  Epistolam Iacobi eiciemus ex hac schola, denn sie soll nichts. Nullam syllabam habet de Christo. Er nennet auch Christum nicht eins nisi in principio. Ich halt, das sie irgents ein Jude gemacht hatt, welcher wol hat horen von den christen leuten, abr nit gar zusam schlagen; vnd dieweil er hat gehört, das die christen also sehr auff den glauben in Christum dringen, hat er gedacht: Halt, du wilt in begegnen vnd schlecht die opera treiben! Wie er den thut. De passione et resurrectione Christi sagt er nicht ein wort, das doch allr apostell predigt ist gewest. Dazu ist da kein ordo noch methodus. Jzt sagt er von kleidern, bald von zorn, fellet imer von einem auff das ander. Er gibet ein gleichnus: Sicut corpus non vivit sine anima, ita fides nihil est sine operibus. Ei Marge, Gotts mutter! Wie ein arme similitudo ist das! Confert fidem corpori, cum potius fides animae fuisset comparanda! Das haben auch die alten gesehen¹⁴, darumb haben sie die epistolam nicht pro catholica epistola gehalten (WA Tr 5:157). 

I say "recorded in the Table Talk" because Luther didn't write these words, someone else transcribed them, context unknown. The comments though match up to the sentiment found in Luther's earlier statements.
  
Did Luther simply arrive at this authorship conclusion without precedent? No. He maintained a position that echoed other voices from church history. Eusebius and Jerome both recorded doubts to the apostolicity and canonicity of James. The great Roman Catholic humanist Scholar Erasmus likewise questioned the authenticity of James, as did Cardinal Cajetan, one of the leading 16th Century Roman Catholic scholars. Some think the early influence of Erasmus impacted Luther view. consider the speculation from Lutheran scholar J.M Reu:
It is possible that the position of Erasmus had influenced Luther in some particulars. Luther had first expressed his critical attitude towards the Epistle of St. James in his Resolutiones of 1519; afterwards more energetically in De Captivitate Babylonica. Under such conditions we have no reason to be surprised that Luther entered into the question in his New Testament of 1522, especially as the fundamental understanding of Scripture that had come to him compelled him to take a stand, at least concerning James, and furthermore, he did not think that these matters were to be kept hidden from the congregations but even discussed them in his sermons [M. Reu, Luther’s German Bible: An Historical Presentation Together with a collection of Sources (Ohio: The Lutheran Book Concern, 1934), 176].
Reu points out that Erasmus "had assumed a critical attitude towards [James, Jude, Hebrews, Revelation] in the Annotationes of 1516" (Reu, 175). Reu then later speculates, that Luther publicly altered his criticisms of James "to keep his personal opinions in the background, especially as the German Bible was intended for the whole congregation" [Reu, 226]. Reu documents the changes from Luther's September-Testament to the softening revision in the 1530's (p.226-227):
In fine, he wanted to guard against those who tried to rely on faith without works but he was too weak in spirit, understanding and words, and so he rends Scripture and opposes Paul and all Scripture, trying to accomplish by the occasion of the Law what the other apostles effect by incentives to love. Therefore I will not have him reckoned in my Bible in the number of the real chief books, but will not prevent anyone from esteeming him as he pleases, for otherwise it contains many good sayings. One man is reckoned, as no man in worldly affairs. How then should this one alone count against Paul and all the rest of Scripture ?
Then, this statement was modified in the 1530's:
In fine, he wanted to guard against those who tried to rely on faith without works but was too weak for the undertaking, trying to accomplish by the coercion of the Law what the other apostles effect by incentives to love. Therefore I will not have him reckoned in my Bible in the number of the real chief books, but will not prevent anyone from esteeming him as he pleases. For it contains many good sayings.
Did Luther Want to Throw the Epistle of James in the Stove?
Was Luther’s hatred for the Epistle of James was so severe, he wanted to burn the book in a stove? Most often, this charge comes from a comment found in The Licentiate Examination Of Heinrich Schmedenstede, July 7 1542. At one point, James chapter 2 is raised as a potential counter argument against justification by faith alone: “James says that Abraham was justified by works. Therefore, justification is not by faith.” Protestant Heinrich Schmedenstede countered this by saying, “James is speaking of works as the effect of justification, not as the cause.” Luther then gave his opinion:
That epistle of James gives us much trouble, for the papists embrace it alone and leave out all the rest. Up to this point I have been accustomed just to deal with and interpret it according to the sense of the rest of Scriptures. For you will judge that none of it must be set forth contrary to manifest Holy Scripture. Accordingly, if they will not admit my interpretations, then I shall make rubble also of it. I almost feel like throwing Jimmy into the stove, as the priest in Kalenberg did (LW 34:318).

Original text:  Illa epistola Iacobi nobis multum facesseit negotii. Eam enim solam amplectuntur reliquis omnibus omissis papistae. Ego hactenus solitus sum iam operare et interpretari secundum sententiam reliquae scripturae. Nam nihil ex ea contra manifestam scripturam sanctam statuendum esse iudicabitis. Si igitur non admittent meas interpretationes, tum faciam quoque ex ea vastationem. Ich wil schier den Zedel in den offen werffen wie der pfaff vom Kalenberg (WA 39.2:199).

Luther does not deny the answer put forth by Schmedenstede. What Luther does point out is heavy Roman Catholic reliance on James 2. It troubled him that this passage weighed so strongly in Roman Catholic arguments against justification by faith alone. Interestingly, he also says that he has previously interpreted it “according to the sense of the rest of Scriptures” (which will be shown below) But what of the comment “I feel like throwing Jimmy in the stove”? What is not explicit in the context above is the historical background of Luther’s comment. The editors of Luther’s Works explain,
The preacher of Kalenberg, when visited by the duchess, heated the room with the wooden statues of the apostles. The statue of James was the last and as the preacher shoved it into the stove he exclaimed, “Now bend over, Jimmy, you must go into the stove; no matter if you were the pope or all the bishops, the room must become warm" (LW 34:318, cf. WA 39.2:199, n.2).

 Even though Luther isn't saying to throw the actual Epistle of James into the stove, it's obvious there's a sarcastic intent to his comment and frustration being expressed. For a full treatment of this quote, see this entry.   

Luther Did Not Reject James Because of "Faith Alone"?
There is also evidence from Luther that complicates the information above. For instance, even while criticizing James, he positively quoted it throughout his career. He also occasionally preached from the book: in 1536 Luther preached on James 1:16-21, Sermon for the Fourth Sunday after Easter, "Two things there are which part men from the Gospel: one is angry impatience, and the other evil lust. Of these James speaks in this epistle." But more surprisingly, there are also statements in which Luther harmonized James and Paul on the relationship of faith and works!

In his early lectures on Romans, Luther provides a harmonious explanation of James on faith and works (LW 25:234-235), "Therefore justification does not demand the works of the Law but a living faith which produces its own works" [LW 25:235]:
Therefore, when St. James and the apostle say that a man is justified by works, they are contending against the erroneous notion of those who thought that faith suffices without works, although the apostle does not say that faith justifies without its own works (because then there would be no faith, since, according to the philosophers, “action is the evidence that form exists”), but that it justifies without the works of the Law. Therefore justification does not demand the works of the Law but a living faith which produces its own works (LW 25:235).

Original text: Igitur quando b. Iacobus et Apostolus dicunt ex operibus hominem Iustificari, contra falsam intelligentiam disputant eorum, qui fidem sine operibus suis sufficere putabant, Cum Apostolus Non dicat, quod fides sine suis propriis operibus (quia tunc nec fides esset, cum 'operatio arguat formam adesse' secundum philosophos), Sed sine operibus legis Iustificat. Igitur Iustificatio requirit non opera legis, Sed viuam fidem, quę sua operetur opera. (WA 56:249). 

In 1530, Luther answered the question, "Why does James [2:26] say, 'Faith apart from works is dead'?" Luther answered:
James is dealing with a moral point, not theological, just as he is almost entirely about morality. Morally speaking, it is true that faith without works is dead- that is, if faith does not do works or if outward works do not follow faith. In this way then, faith cannot exist apart from works; that is, it cannot fail to do works, else there is no faith alone.

We, however, are dealing with a theological point here since we are discussing justification before God. Here we assert that faith alone is counted as righteousness before God, apart from works and merits." (LW 61:183-184).

Original text:  Iacobus versatur in loco Morali, non in Theologico, sicut fere totus est moralis. Moraliter loquendo verum est fidem sine operibus esse mortuam i. e. si non operetur fides, aut si fidem non sequantur opera foris. Hoc enim modo fides non potest esse sine operibus, i. e. non potest non operari, aut nulla est fides ibi.

Sed nos hic in loco Theologico sumus, ubi de iustificatione coram Deo loquimur. Hic dicimus fidem solam pro iusticia reputari coram Deo, sine operibus et meritis, Quia Deus merita nostra non curat, sed fidei donat per promissiones suas (WA 30.2:664).

In The Disputation Concerning Justification, Luther answered this spurious proposition: Faith without works justifies, Faith without works is dead (Jas. 2:17, 26). Therefore, dead faith justifies. Luther responded:
The argument is sophistical and the refutation is resolved grammatically. In the major premise, ‘faith’ ought to be placed with the word ‘justifies’ and the portion of the sentence ‘without works justifies’ is placed in a predicate periphrase and must refer to the word ‘justifies,’ not to ‘faith.’ In the minor premise, ‘without works’ is truly in the subject periphrase and refers to faith. We say that justification is effective without works, not that faith is without works. For that faith which lacks fruit is not an efficacious but a feigned faith. ‘Without works’ is ambiguous, then. For that reason this argument settles nothing. It is one thing that faith justifies without works; it is another thing that faith exists without works. [LW 34: 175-176].

Original text: Argumentum est sophisticum et ἔλεγχος per grammaticam solvitur. In maiore fides debet constitui cum verbo iustificat, et particula sine operibus iustificat ponitur in periphrasi praedicati et est referenda ad verbum iustificat, non ad fidem. In minore vero sine operibus est in periphrasi subiecti, et ad fidem refertur. Nos loquimur, quod iustificatio fiat sine operibus, non quod fides sit sine operibus. Nam illa, quae caret fructu, non est efficax, sed ficta fides. Est igitur aequivocatio: sine operibus. Ideoque nihil concludit hoc argumentum. Aliud est fidem iustificare sine operibus, aliud est esse fidem sine operibus (WA 39.1:106).

In a 1521 sermon Luther is recorded as saying,
This is what James means when he says: 2, 26: “Faith which does not work is dead. Just as the body without the soul is dead, so faith without works is also dead” (James 2[:17,26]).  This does not mean that faith is in a person and does not work, which is impossible, for faith is a living, restless thing. Rather, this means that people should not deceive themselves and think they have faith when they have none of it; rather, they should look at their works, that is, whether they also love their neighbors and do good to them. If they do this, it is a sign they have true faith. However, if they do not do this, then they only have the sound of faith. What happens to them is like the person who examines himself in the mirror. When he goes away, he no longer sees himself. Through looking at other things, he forgets the face he saw in the mirror, as also St. James says (James 1 [:23-24] (LW 79:75-76). 
Original text: Sihe, das meynet S. Jacob. Jaco. ij. "Der glawbe, so er nit wirckt, ist er todt. Und wie der leyb on seel todt ist, so ist auch der glaub on werck todt". Nit das der glaube ym menschen sey und nit wircke, wilchs nitt muglich ist, denn der glawb ist ein lebendig unrugig ding, sondern das sich die menschen nitt selb betriegen und meynen, sie haben den glawbenn, so sie doch nichts davon haben, sondern sollen ansehen yhr werck, ob sie auch yhrn nehisten lieben und yhm woll thun. Thun sie das, so ists ein zeychen, das sie dissen rechten glauben haben. Thun sie aber nit, so haben sie nur das gehore vom glawben. Und geschicht yhn, wie dem, der sich ym spiegel besihet: wenn er davon geht, szo sihet er sich nymmer, und durch ansehen anderer ding vorgisset er des spiegels gesicht, alsz auch Jaco. i. geschrieben stet (WA 8:361-362).

The deceivers and blind masters have stretched this passage of James so far that they have destroyed faith and set up only works, as if righteousness and salvation consist not of faith but of works. To this great darkness they have added an even greater darkness and have taught only good works which are of no benefit to your neighbor, such as fasting; saying many prayers; observing festival days; not eating meat, butter, eggs, and milk; building churches, cloisters, chapels, and altars; instituting Masses, vigils, hours; wearing gray, white, or black clothes; becoming clergy; and innumerable similar things from which no one has any benefit or enjoyment, and all of which God condemns, and justly. St. James, however, says this intentionally, since a Christian life is nothing except faith and love. Love means nothing else than doing good and being useful to all people, enemies and friends. Where faith is correct, it certainly loves and acts toward others in love, just as Christ has acted in his faith. Thus each one should be on his guard so that he does not have a dream and fiction in his heart instead of faith, and thus deceive himself. He can recognize this in nothing better than in works of love. Christ Himself gives the sign of this when He says, ‘By this everyone can know that you are My disciples, if you love one another’ (John 13:35). Therefore, St. James means to say, ‘Be on your guard, lest your life not serve others, you live for yourself, and you take no interest in your neighbor, for then your faith is certainly nothing, since it does not do what Christ has done for it.’ Yes, he does not believe that Christ has done good for him; otherwise he would not omit also doing good for his neighbor (LW 79:76).

Original text: Dissen spruch Jacobi haben die vorkurer und blinden meyster szo weyt gezogen, bysz das sie den glawben vortilget unnd nur die werck auff gericht haben, alsz stehe die gerechtickeyt und selickeyt nit ym glawben, szondern yn den wercken. Zu der grossen finsternisz haben sie darnach noch eyn gröszere thunn unnd nur die gutte werck geleret, die dem nehisten feyn nütz sind, alsz fasten, viel gepet sprechen, feyren, nit fleysch, putter, eyer, milch essen, kirchen, kloster, capeln, altar bawen, mesz, vigilien, horas stifften, graw, weisz, schwartz kleider tragen, geistlich werden, und der unzehlich gleichen, davon doch keyn mensch nütz noch geniesz hatt, wilch auch got alle vordampt, und billich. Aber S. Jacobus will das, sintemal eyn Christlich leben ist nichts denn glawbe unnd liebe. Liebe ist nichts denn eyttel woll thun und nuy seyn allen menschen, feynden und freunden. Unnd wo der glawb recht ist, szo liebt er auch gewiszlich und thut den andern ynn der liebe, wie yhm Christus than hatt ynn seynem glawben. Szo soll nu eyn iglicher sich fursehen, das er nit eynen trawm und geticht an stat des glaubens ym hertzen habe und sich selber betriege: das wirt er bey seynem ding alsz woll erkennen, alsz bey den wercken der liebe. Wie auch Christus dasselb zeychen gibt und spricht: "Da bey kan man wissen, das yhr meine iunger seyt, szo yhr euch untereinander liebt". Darumb will S. Jacob sagen: Sihe fur dich, steht dein leben nit also, das es andern diene, und du fur dich selbs lebist, nympst dich deynsz nehisten nit an, szo ist deyn glawbe gewiszlich nichts, denn er thut nit, wie yhm Christus than hatt.  Ja er glowbt nit, das yhm Christus woll than hat, sonst liesz er nitt, er thet seynem nehisten auch wol (WA 8:362). 

Similarly, In a 1522 sermon Luther states:
This is what St. James means in his Epistle when he writes: “Faith without works is dead” (James 2[:26]). That is, when works do not follow, it is a sure sign that there is no faith there, but a dead thought and dream, which they falsely call “faith.” This is how we understand these words of Christ: “Make friends for yourselves with the unrighteous mammon” [Luke 16:9]; that is, plainly demonstrate your faith with external giving, by which you gain friends, so that from your obvious works the poor can be witnesses that you have genuine faith. External giving of itself can never make friends, unless it happens from faith. Christ rejects the Pharisees’ alms (Matthew 6[:1–4]); they made no friends with their alms, because their hearts were false. Now no heart ever becomes right without faith, so that even nature is forced to confess that no works make anyone righteous, but the heart must first be righteous and good (1522 published sermon, LW 78:324).
Original text: Das meynet S. Jacobus yn seyner Epistel, da er spricht "Der glawb on werck ist todt". Das ist, weyll die werck nicht folgen, ists eyn gewiß heychen, das keyn glaub da sey, sondern eyn todter gedancke und trawm, den sie falschlich glawben nennen. Also verstehen wyr nu diß wortt Christi "Machet euch freundt von dem unrechten Mammon", das ist: beweyset offenbar mit eußerlichem geben ewren glawben, damit yhr freundt ubirkomet, das die armen ewrs offinbarn wercks zeugen seyn kunden, das yhr rechtschaffen glauben habt, denn das eußerlich geben von yhm selber mochte nymmer mehr freundt machen, wo es nicht auß dem glawben geschech. Sintemal Christus Matt. 6. Der Phariseer almoßen verwirfft, das sie keyn freundt damit machten, weyll das herz falsch war. Nu wirt yhe keyn herz recht on den glawben, das also auch die natur zwingt zu bekennen, das keyn werck frum macht, sondern das herz zuvor frum und gutt seyn muß (WA 10.3:288). 
Conclusion
The extant evidence of Luther's view is therefore conflicting. On the one hand, Luther overtly doubted the apostolic pedigree of the Epistle of James and saw that it conflicted with Paul. On the other hand, Luther approvingly cited James, preached from it, embraced a harmonious way of understanding James and Paul, and softened his earlier criticisms. This contradictory evidence appears to run parallel throughout his life. It could very well be that definitive answer on Luther's view of James... is that there is not a definitive answer! It seems to me that in light of Rome's defenders generally, Luther argued James was not canonical, particularly if pressed by Rome's advocates that James refuted justification by faith alone. In other contexts generally, Luther treated James as harmonious with the rest of Scripture. As I've read Luther over the years, the balance of these positions seems to lean more towards the former evidence that James was not an apostolic witness. This could simply be the result of the continual polemical conflicts Luther found himself in. 

Perhaps Reu's speculation that Erasmus influenced Luther on authorship and LW's conclusion that his papal opponents were citing James against him may be the pertinent factors that explain the confusion as to Luther's view. For both of these speculations, I would need to see evidence. For the former, I have never seen a statement from Luther demonstrating he was following Erasmus on James. For the later, I searched through my collection of early polemical writers against Luther and did not come across meaningful early uses of James being cited against Luther... though I suspect it certainly was! It seems to be assumed as a papal criticism in the many disputations Luther took part in throughout his life. 

Addendum #1: Interacting With Rome's Defenders on Luther's View of James
If you're dealing with Luther's detractors, most often Rome's defenders... keep in mind that one of the main reasons they're bringing up Luther's view of James is that the intention is to put forth the infallible authority of Rome in determining the canon of the Bible. Simply in response: it does not follow that unless Rome infallibly determines the canon of the Bible, everyone will pick and choose their own Biblical canon. Despite Luther's view of James, this has practically not happened. To my knowledge, there was not any significant following of Luther on his view of James, nor has Protestantism created 30,000 canons to match the alleged 30,000 denominations Rome's defenders continually squawk about. I would exhort the reader to realize that the choice between the infallible authority of Rome and total anarchy is a false dilemma. 

If you're engaging Rome's defenders on the canon and Luther's view of the canon comes up, a counter question that they should be forced to consider is answering.... why has the canon of the Bible remained very consistent despite Luther's views? Is Rome responsible for this? Is so, how? If Luther's view amounts to a subjective personal canon, why is it that the canon has been so stable since the publication of Luther's opinions found in his translation of the Bible?

I've argued elsewhere that Erasmus, Cajetan, and Luther had a right within the Roman Catholic system to engage in Biblical criticism and debate over the extent of the canon previous to the dogmatic declarations of the Council of Trent. All expressed some doubt. Theirs was not a radical higher criticism. The books they questioned were books that had been questioned by previous generations. The editors of Luther’s Works note that both Eusebius and Jerome raised or confirmed similar doubts to the apostolicity and canonicity of James:
In the earliest general history of the church, Eusebius: The Ecclesiastical History (II, xxiii, 25), the author… writes, “Such is the story of James, whose is said to be the first of the Epistles called Catholic. It is to be observed that its authenticity is denied, since few of the ancients quote it, as is also the case with the Epistle called Jude’s.”… Eusebius also includes both epistles in his list of “Disputed Books” (History, III, xxiv, 3)…Cf. the statement by Jerome (d. 420) in his Liber de Viris Illustribus (II) concerning the pseudonymity ascribed to the epistle of James and its rather gradual attainment of authoritative status [LW 35:396].

Follow this up the following from The New Catholic Encyclopedia

According to Catholic doctrine, the proximate criterion of the Biblical canon is the infallible decision of the Church. This decision was not given until rather late in the history of the Church (at the Council of Trent). Before that time there was some doubt about the canonicity of certain Biblical books, i.e., about their belonging to the canon.
The New Catholic Encyclopedia, Vol. III Can to Col (New York: Mcgraw-Hill, 1967), p. 29.
Nihil Obstat: John P. Whalen, M.A., S.T.D. Censor Deputatus
Imprimatur: Patrick O'Boyle, D.D. Archbishop of Washington, August 5, 1966

Rome's defender Robert Sungenis admitted the validity of my argument in regard to Trent and the canon. 

Addendum #2: John Warwick Montgomery
Here's nitpicking myself: Back in 2004, I addressed the "epistle of straw" comment in Luther's View of the Canon of Scripture. I cited John Warwick Montgomery writing, 

Few people realize — and liberal Luther interpreters do not particularly advertise the fact — that in all the editions of Luther’s Bible translation after 1522 the—Reformer dropped the paragraphs at the end, of his general Preface to the New Testament which made value judgments among the various biblical books and which included the famous reference to James as an “Epistle of straw.
In my old paper I summarized Montgomery saying, "An interesting fact about this quote (hardly ever mentioned by Luther-detractors!) is that it only appears in the original 1522 Preface to the New Testament." LW 35:358, fn. 5 though states: "The portions here set in brackets did not appear in any editions of the complete Bible, nor in editions of the New Testament after 1537." It appears to me that editions of Luther's New Testament previous to 1537 and incomplete editions of the Bible previous to 1534 probably did include the "epistle of straw" comment.
