Luther Accepted the Reformed view of the Eucharist? It was not a Dividing issue?

 Here's a Luther quote sent to me recently, said to be Luther's positive response to the Reformed on the Eucharist:

"We have now heard your answer and confession, viz., that you believe and teach, that in the Holy Eucharist, the true body and true blood of Christ are given and received, and not alone bread and wine: also, that this giving and receiving take place truly and not in imagination. Although you take offense in regard to the wicked, yet you confess with St. Paul that the unworthy receive the Lord's body, where the institution and word of the Lord are not perverted: - about this we will not contend. Hence, as you are thus minded, we are one, and we acknowledge ~and receive you as our dear brethren in the Lord." Martin Luther, Said at Wittenberg Concord

First, let's take a look at this quote to find out where it comes from. Second, let's briefly look to see if this is an example of Lutherans and Reformed together.

Documentation
The person sending me this quote was gracious enough to provide meaningful documentation. This English text comes from James William Richard, Philip Melanchthon, the Protestant Preceptor of Germany, 1497-1560, 253. This source took the quote from Julius Kostlin, Martin Luther, Sein Leben und Seine Schriften II, 349. Unfortunately, Kostlin doesn't document what source he was using, other than referring to a report by Myconius. The text Kostlin may have used was Dr. Martin Luthers Sämmtliche Schriften 20: 2111 (17:2555-2557).

This text is an account of the Wittenberg Concord of 1536. An odd sort of AI generated English translation can be found here. 

The Wittenberg Concord

Many historical accounts and scholarly opinions of the Wittenberg Concord exist online documenting the tedious details. Briefly, what you need to know: the parties involved were the Wittenberg theologians and those from upper Germany, represented primarily by Martin Bucer (of Strassburg).   A statement of agreement produced by the Concord on the Lord's Supper can be found here. 

Amy Nelson Burnett, trans., “The Wittenberg Concord 1536,” Reformation and Renaissance Review 18, no. 1 (March 2016): 25–26.

Bucer's side held the Lord's Supper was only for the spiritual nourishment of the soul and that it was not intended for the wicked. For the former issue, Luther wrote to Bucer a few years earlier: "We give thanks to God that we agree at least, as you write, insofar as we both confess that the body and blood of Christ are truly present in the Lord’s Supper, and that together with the Words [of Institution] they are distributed as food of the soul" (LW 50:7). Luther's contention was with the later point. In the same earlier letter, Luther wrote:

If, then, we confess that the body of Christ is truly distributed to the soul as food, and if there is no reason for us not to say that the body of Christ is also distributed in this way to the unbelieving soul, although the unbelieving soul does not receive it—just as the light of the sun is offered equally to the seeing and to the blind—I am wondering why it bothers you people to confess also that the body of Christ is offered, together with the bread, externally to the mouth of the believer and unbeliever alike; for through the concession that the body of Christ is distributed to individual souls it is, of course, necessarily granted that the body is present and can be distributed in many places at the same time. If this thought has not yet matured among you people, however, then I think this matter should be postponed and further divine grace should be awaited. I am unable to abandon this position, and if, as you write, you do not think that this position is demanded by Christ’s words, my conscience nevertheless holds that it is required. Therefore I am unable to confess with you that total unity exists between us, if I do not wish to harm my conscience, [or] rather, if I do not wish to sow among us the seed of far worse turmoil for our congregations, and of more dreadful future dissension among us (LW 50:7-8).

You can see in the Wittenberg Concord statement above, the issue appeared to have been settled. Without getting lost in the tedious details, both sides were pouring their own meaning into the category of people described as "unworthy." As Gordon A. Jensen explains:   

For the Lutherans, the “unworthy” covered all believers who were simul iustus et peccator. One’s piety does not determine Christ’s presence in the meal, but it could affect whether Christ’s body brought life or judgment. Bucer, however, considered the unworthy as a distinct third category. For him, the unworthy included only those who were struggling with their faith, not unbelievers. He thus insisted that Christ’s presence in the meal depended on the faith of the recipient, while the Lutherans focused on the one who gave the sacrament, taking an objective approach to the sacrament. The Word of forgiveness and grace comes from outside of the communicant (extra nos), in the person of Christ, present in the bread.

The issue of contention for Bucer was Christ being physically present in the elements even if they were received by a faithless person. For Bucer, an ungodly person is simply ingesting bread and wine. His emphasis was to avoid Romanism. For the Lutherans, "If the validity of the sacrament depended on the faith of the recipient, then it became a works-righteousness, leading to self-justification" (Jensen, 102).

Conclusion

It appears to me the two sides in essence, agreed to disagree, perhaps while thinking they both agreed? You'll find ample statements though that this unity was not maintained. Even the source which began this entry stated, "The Wittenberg Concord, as it is known in history, failed to effect a lasting union...".

Lutherans and Reformed together? As far as the statement goes, I would be keener on it if the statement actually explained the areas of disagreement more carefully, yet agreed to disagree for the sake of unity. 

Fake Luther Quote: "It is a sweet and pious belief that the infusion of Mary's soul was effected without original sin..."

 

This image above was pulled off Facebook. In the first quote, Luther supposedly said,  

"It is a sweet and pious belief that the infusion of Mary's soul was effected without original sin; so that in the very infusion of her soul she was also purified from original sin and adorned with God's gifts, receiving a pure soul infused by God; thus from the first moment she began to live she was free from all sin." -Martin Luther's Sermon "On the Day of the Conception of the Mother of God," 1527.

If you're thinking, "that really doesn't sound like Luther," then kudos to you for your discernment skills! This was one of the first weird Roman Catholic Luther quotes I investigated. It just didn't sound right. Eventually I compiled this entry documenting my journey with this quote. Since the quote still circulates online, here's what you need to know:

1. Where does the quote come from? The English version of this quote probably comes from a translation of Roman Catholic historian Hartmann Grisar's book, Luther, IV. Whichever Roman Catholic apologist originally cut-and-pasted it from the book to the Internet neglected to mention Grisar states, 

The sermon was taken down in notes and published with Luther's approval. The same statements concerning the Immaculate Conception still remain in a printed edition published in 1529, but in the later editions which appeared during Luther's lifetime they disappear. 

and also: 

As Luther's intellectual and ethical development progressed we cannot naturally expect the sublime picture of the pure Mother of God, the type of virginity, of the spirit of sacrifice and of sanctity to furnish any great attraction for him, and as a matter of fact such statements as the above are no longer met with in his later works.

2. Who deleted this quote? Luther did.

3. Why did Luther delete this quote? The sermon collection it appeared in was put together by Stephen Roth. Roth actually added in material not from Luther. Luther was highly displeased with what Roth put together, thus provoking a new edition, hence the deletion. 

4. Did Luther write this quote? He probably did not. The editors of Luther's Works point out: 

Originally, Luther may have held something similar to the Thomist position, put forward in the Festival Postil (1527), sermon on the conception of Mary, WA 17/2:287-288, though the material in question seems to be solely the responsibility of its editor, Stephan Roth (d.1546), and was removed from the 1528 and subsequent editions: see StL 11:959-961; Baseley 1:50-51. In his later preaching, Luther affirmed that Mary had been both conceived and born in sin and connected her purification from sin with the work of the Holy Spirit at the time of Christ's conception... (LW 58:434-435, fn. 10).

Conclusion
It amazes me that this quote still circulates as Roman Catholic propaganda on the Internet. We've been given this incredible ability to have immediate information, yet, Roman Catholic propagandists don't do the basic work of a looking up a quote before splattering it all over the Internet. These are the same people that claim reading the church fathers will make one become Roman Catholic! 

Four Surprising Facts About John Calvin and the “Apocrypha”?

I came across an interesting John Calvin article written by one of the apologists from Catholic Answers: Four Surprising Facts About John Calvin and the “Apocrypha”. Let's take a look at their first surprising fact: "Calvin Implicitly Concedes that the Deuterocanon Supports Catholic Teachings."

Quoting a section from Calvin's Acts of the Council of Trent with the Antidote (Acta synodi Tridentinae cum antidoto), the author explains Calvin believed the Apocryphal books clearly taught: purgatory, the worship of saints, satisfactions, and exorcisms. Calvin of course, rejected the Apocrypha as canonical scripture. Despite this rejection, Rome's defender states Calvin realized the clarity of these doctrine in the Apocrypha. He states, "John Calvin: Admitted the Deuterocanon teaches Purgatory, veneration of the Saints, exorcisms, and other doctrines denied by Protestants." Therefore, this implies:

...if Catholics are right about the Deuterocanon, then we’re also right about Purgatory, praying to (not worshipping) the Saints, exorcisms, and so on. That’s pretty huge.

Let's take a closer look at Calvin's text to see if he admits the Apocrypha (Deuterocanon) validates Rome's unique doctrines. I contend that the context demonstrates no such thing. Rather, Calvin was of the opinion that the Papacy would read into any portion of the Bible (canonical or not) to make it say what they wanted it to say. The passage below from Calvin is lengthy, and only slightly edited. 

Context

First, they ordain that in doctrine we are not to stand on Scripture alone, but also on things handed down by tradition. Secondly, in forming a catalogue of Scripture, they mark all the books with the same chalk, and insist on placing the Apocrypha in the same rank with the others... Lastly, in all passages either dark or doubtful, they claim the right of interpretation without challenge...for whatever they produce, if supported by no authority of Scripture, will be classed among traditions, which they insist should have the same authority as the Law and the Prophets. What, then, will it be permitted to disapprove? for there is no gross old wife’s dream which this pretext will not enable them to defend; nay, there is no superstition, however monstrous, in front of which they may not place it like a shield of Ajax. Add to this, that they provide themselves with new supports when they give full authority to the Apocryphal books. Out of the second of the Maccabees they will prove Purgatory and the worship of saints; out of Tobit satisfactions, exorcisms, and what not. From Ecclesiasticus they will borrow not a little. For from whence could they better draw their dregs? I am not one of those, however, who would entirely disapprove the reading of those books; but in giving them in authority which they never before possessed, what end was sought but just to have the use of spurious paint in coloring their errors?...

...they devise a most excellent remedy, when they adjudge to themselves the legitimate interpretation of Scripture. Who can now imagine any improvidence in them? By one article they have obtained the means of proving what they please out of Scripture, and escaping from every passage that might be urged against them. If Confession is to be proved, they are ready with — “Show yourselves to the priests.” If it be asked, Whether recourse should be had to the intercession of the dead? the passage will immediately occur, “Turn to some one of the saints;” also, “For this every holy man will pray to thee.” Nor will Purgatory be left without a sure foundation, for it is written, “He shall not come out thence till he shall have paid the uttermost farthing.” In short, anything may be made of anything! When they formerly produced such passages they made themselves ridiculous even to children. Now, if credit is given them, the right of authorized interpretation will remove every doubt. For what passage can be objected to them so clear and strong that they shall not evade it? Any kind of quibble will at once relieve them from difficulty. Against opposing arguments they will set up this brazen wall — Who are you to question the interpretation of the Church? This, no doubt, is what they mean by a saying common among them, in that Scripture is a nose of wax, because it can be formed into all shapes. If postulates of this kind were given to mathematicians, they would not only make an ell an inch, but prove a mile shorter than an ell, till they had thrown everything into confusion.

What, then, are we to do with this victorious and now, as it were, triumphal Session? Just stand and let the smoke clear away. In regard to Traditions, I am aware that not unfrequent mention of them is made by ancient writers, though not with the intention of carrying our faith beyond the Scriptures, to which they always confine it. They only say that certain customs were received from the Apostles. Some of them appear to have that origin, but others are unworthy of it. These touch only upon a few points, and such as might be tolerated. But now we are called to believe, that whatever the Romanists are pleased to obtrude upon us, flowed by tradition from the Apostles; and so shameless are they, that without observing any distinction, they bring into this class things which crept in not long ago, during the darkness of ignorance. Therefore, though we grant that the Apostles of the Lord handed down to posterity some customs which they never committed to writing; still, first, this has nothing to do with the doctrine of faith, (as to it we cannot extract one iota from them,) but only with external rites subservient to decency or discipline; and secondly, it is still necessary for them to prove that everything to which they give the name is truly an apostolical tradition. Accordingly they cannot, as they suppose, find anything here to countenance them either in establishing the tyranny of their laws, by which they miserably destroy consciences, or to cloak their superstitions, which are evidently a farrago gathered from the vicious rites of all ages and nations. We especially repudiate their desire to make certainty of doctrine depend not less on what they call agrafa, (unwritten,) than on the Scriptures. We must ever adhere to Augustine’s rule, “Faith is conceived from the Scriptures.”

Of their admitting all the Books promiscuously into the Canon, I say nothing more than it is done against the consent of the primitive Church. It is well known what Jerome states as the common opinion of earlier times. And Ruffinus, speaking of the matter as not at all controverted, declares with Jerome that Ecclesiasticus, the Wisdom of Solomon, Tobit, Judith, and the history of the Maccabees, were called by the Fathers not canonical but ecclesiastical books, which might indeed be read to the people, but were not entitled to establish doctrine. I am not, however, unaware that the same view on which the Fathers of Trent now insist was held in the Council of Carthage. The same, too, was followed by Augustine in his Treatise on Christian Doctrine; but as he testifies that all of his age did not take the same view, let us assume that the point was then undecided. But if it were to be decided by arguments drawn from the case itself, many things beside the phraseology would show that those Books which the Fathers of Trent raise so high must sink to a lower place. Not to mention other things, whoever it was that wrote the history of the Maccabees expresses a wish, at the end, that he may have written well and congruously; but if not:, he asks pardon. How very alien this acknowledgment from the majesty of the Holy Spirit! [source]

Conclusion

Granted, Calvin's main argument against the Apocrypha rests on the fact of its spurious canonicity in church history; but the context demonstrates Calvin thought the Council of Trent was interpreting the passages of the Bible the way it needed to in order to substantiate their unique doctrines. Why would Calvin be admitting the Deuterocanon proved Trent's unique doctrines, and then go on to say that Trent treated the text of the Bible like a wax nose ("Scripture is a nose of wax, because it can be formed into all shapes") bending a passage any way it wanted to? It isn't consistent. 

But maybe Calvin was inconsistent... maybe he really did think the Apocrypha taught purgatory, the worship of saints, satisfactions, and exorcisms, etc.? Let's take one example, Purgatory, by popping over to Calvin's magnum opus (and that which ultimately defines his theology): The Institutes of Christian Religion. There we find Calvin going through all the popular Roman Catholic Biblical proof texts for purgatory. In his treatment of 2 Maccabees 12, Calvin writes of what the passage is actually addressing... and it isn't Rome's doctrine of purgatory:

...[T]he piety of Judas is praised for no other distinction than that he had a firm hope of the final resurrection when he sent an offering for the dead to Jerusalem [2 Macc. 12:43]. Nor did the writer of that history set down Judas’ act to the price of redemption, but regarded it as done in order that they might share in eternal life with the remaining believers who had died for country and religion. This deed was not without superstition and wrongheaded zeal, but utterly foolish are those who extend the sacrifice of the law even down to us, when we know that by the advent of Christ what was then in use ceased. [Institutes III.5.8].

While Calvin wrote commentaries on almost every book of the Bible, he did not write commentaries on the Apocrypha.  Therefore, extracting out Calvin's interpretations of passages from the Apocrypha will be slim. What we find though in the rare instance in which Calvin exegetes an Apocryphal passage, he denies Trent's interpretation.  Thus, the first "surprising fact about John Calvin and the Apocrypha" turns out not to be a fact, and therefore not surprising.

Addendum

Many years ago, I picked up a "four views" book on hell. The person defending the Roman Catholic view ("The Purgatorial view") was Zachary J. Hayes. As to Rome's popular prooftext 2 Maccabees 12:41-46, Hayes notes, The Council of Trent maintained this passage provides a scriptural basis, but they were reading the passage with "the mindset of late medieval people" (p. 103). He contrasts this with contemporary Roman Catholic exegetes, and see these verses differently, as "evidence for the existence of a tradition of piety which is at least intertestamental and apparently served as the basis for what later became the Christian practice of praying for the dead and performing good works, with the expectation that this might be of some help to the dead" (pp. 104-105). Hayes says modern Roman Catholic exegetes conclude:  

"Since the text seems to be more concerned with helping the fallen soldiers to participate in the resurrection of the dead, it is not a direct statement of the later doctrine of purgatory" (p. 105).

Catholic or Roman Catholic? Microaggression?

Back in 2013 I received an "infraction" from a Catholic Answers moderator for using the phrases, "Roman church" and "Joining Rome":

"Although [your]post does not reach the level of contempt for Catholicism, it does show a general disrespect... I would highly suggest you change your tone to be in accordance with CAF rules in the future."

I was having a casual interaction with a Roman Catholic participant (details here). You can see the interaction and how innocuous it was... in fact I was actually defending Roman Catholic apologist Tim Staples! I was told, "The terms 'Roman church' and 'joining Rome' are highly offensive. What Staples joined was the Catholic Church." Using a Catholic Answers web page link I responded:

"Within the Catholic Church there are a number of individual churches, sometimes called rites. One of these is the Roman rite or Roman church. It includes most of the Catholics in the Western world. A Roman Catholic is a Catholic who is a member of the Roman rite."

My Roman Catholic friend responded, 

Nice dodge. You didn't say "Roman Rite." You said "Roman church" and "joining Rome." You're not talking to a cradle Catholic whose never darkened the door of a Protestant church. I am very much aware of the code words you use and why you use them.

And also:

All one has to do is read your blog to see your true feelings and motivations for coming here. You're not fooling anyone.

Conclusion

Upon reflecting on this old encounter, it occurred to me that we have since been inundated by the concept of language microaggression. Here I was back in 2013, being accused of microaggression!

Over the years I've been conflicted with how exactly to refer to those folks over on the other side of the Tiber River. With this blog, I began by simply referring to them as "Catholic." Then, I realized they could potentially make a big deal if I forgot to capitalize the "C." Then I went through a period in which I realized... as much as they make a claim to it, they do not own the word "catholic."  This was in part due to my reading of Luther and reciting the Apostles Creed each week at church. Luther made a strong distinction between the "papists" and the church. He was vigorously against those people defending the Papacy. Embracing Luther's distinction, for many years I've used "defenders of Rome" (which I think Luther would approve of). 

I'm not attempting to insult anyone on the other side of the Tiber River. If we want to play the "my feeling are hurt" game, my feelings are hurt every time they insist the Roman Catholic church is the true church and I should be under the authority of the papacy. So as part of my continual disdain for politically correct language and the accusation of microaggression, you folks that are aligned with the Papacy are: defenders of the Papacy that resides in Rome, and my shorthand for that is: defenders of Rome.  This does not mean I hate you or look down upon you or think you are stupid. Rather, as the Apostles Creed states, I believe in the holy catholic church, and as Luther is purported to have stated, "to go against conscience is neither right nor safe."

Addendum 

Here was me crossing the Tiber, first by taxi, then by foot:

 

Which Catholic is Correct About Martin Luther?

This picture was taken from a recent Facebook discussion group. The picture was augmented with a long diatribe explaining how awful Luther was, from a Catholic perspective. Here was my response:

What you've provided is your personal opinion about Martin Luther. If I'm going to pick personal Catholic opinions, I think an actual Pope's opinion is more relevant than yours:

In 2016 Pope Francis said that Luther was part of a movement giving “greater centrality to Sacred Scripture in the Church’s life.”

Pope Francis has also said: “The spiritual experience of Martin Luther challenges us to remember that apart from God we can do nothing. ‘How can I get a propitious God?’ This is the question that haunted Luther. In effect, the question of a just relationship with God is the decisive question for our lives. As we know, Luther encountered that propitious God in the Good News of Jesus, incarnate, dead and risen. With the concept ‘by grace alone’, he reminds us that God always takes the initiative, prior to any human response, even as he seeks to awaken that response. The doctrine of justification thus expresses the essence of human existence before God.”

Check out this Catholic response: 

"The pope is only infallible when it comes to dogma and only when he sits on the chair of authority."

Wow, that is a complete disconnect! I never mentioned anything about papal infallibility. My point was to highlight how this Catholic Facebook participant and Pope Francis have drastically different personal opinions about Luther. Why should I accept what some random person on the Internet claims and not the opinion of a Pope? 

When you're interacting with Roman Catholics about Martin Luther, you are interacting with their personal opinions about Martin Luther. 

Luther: "She is rightly called not only the mother of the man, but also the Mother of God ... It is certain that Mary is the Mother of the real and true God."

Over the years I've worked through a Roman Catholic article that "documents" the Mariology of the Reformers. The article is sometimes called, "The Protestant Reformers on Mary." Here is a Martin Luther quote that's usually included:

Mary the Mother of God. Throughout his life Luther maintained without change the historic Christian affirmation that Mary was the Mother of God: "She is rightly called not only the mother of the man, but also the Mother of God ... It is certain that Mary is the Mother of the real and true God."[Martin Luther, Weimar edition of Martin Luther's Works, English translation edited by J. Pelikan [Concordia: St. Louis], volume 24, 107].

If you're puzzled as to why this quote is supposed to be shocking to Protestant eyes, it means you're probably not a garden variety fundamentalist that has theological spasms whenever you come upon the phrase "Mother of God." Luther used this phrase occasionally, but did not use it as a term of invocation or worship. When he used it, it was either an expression of the common vernacular of the sixteenth century, a term of respect for her as someone profoundly used by God in a significant way, or it was primarily to say something about Jesus, not Mary. The context below will bear this out. 

Documentation

As is often the case with Roman Catholic propaganda, the documentation is spurious. Someone mixed together the English and German / Latin editions of Luther's writings. This quote isn't from WA 24 in the Weimar edition, it's from volume 24 of the English edition. 

The origin of this quote may be from a 1992 Catholic Answers article by Father Mateo, CRI's Attack on Mary: Part 1. The article states, 

Throughout his life Luther used and defended Mary’s title “Mother of God” against all comers. “She is rightly called not only the mother of the man, but also the Mother of God. . . . It is certain that Mary is the Mother of the real and true God.”(Jaroslav Pelikan, ed., Luther’s Works (St. Louis: Concordia), vol. 24, 107.) (I wonder about CRI’s consistent failure throughout to mention Protestant sources in praise of Mary.)

It's possible Father Mateo actually mined out this quote. It looks like someone took Mateo's words, changed them a little bit, adding Weimar to the documentation.

Context
We say of every human being that he eats, drinks, digests, sleeps, wakes, walks, stands, works, etc., although the soul participates in none of these activities, but only the body. And yet this is said of the entire person, who has a body and a soul. For it is one person, by reason not only of the body but of both the body and the soul. Again, we say that man thinks, deliberates, and learns. According to his reason or soul, he can become a teacher or master, a judge, councilor, or ruler. Neither the body nor any one of its members gives him this competence. And yet we say: “He has a clever head; he is sensible, learned, eloquent, artistic.” Thus it is said of a woman that a mother carries, bears, and suckles a child, although it is not her soul but only her body that makes her a mother. And still we ascribe this to the entire woman. Or if someone strikes a person on the head, we say: “He has struck Hans or Greta.” Or if a member of the body is injured or wounded, we think of the whole person as being wounded.

I am using these simple illustrations to demonstrate how two distinct natures must be differentiated in the Person of Christ and yet how this still leaves the Person a whole and undivided entity. Whatever Christ says and does, both God and man say and do; yet each word and action is in accord with the one or the other nature. He who observes this distinction is safe and on the right path. He will not be led astray by the erroneous ideas of heretics, ideas which come into being solely because they do not properly join what belongs together and is united, or because they do not properly separate and distinguish what must be distinguished.

Therefore we must adhere to the speech and expressions of Holy Writ and retain and confess the doctrine that this Christ is true God, through whom all things are created and exist, and at the same time that this same Christ, God’s Son, is born of the Virgin, dies on the cross, etc. Furthermore, Mary, the mother, does not carry, give birth to, suckle, and nourish only the man, only flesh and blood—for that would be dividing the Person—but she carries and nourishes a son who is God’s Son. Therefore she is rightly called not only the mother of the man but also the Mother of God. This the old fathers taught in opposition to the Nestorians, who objected to calling Mary “Mother of God” and refused to say that she had given birth to God’s Son.

Here we must again confess with our Creed: “I believe in Jesus Christ, God the Father’s only Son, our Lord, born of the Virgin Mary, suffered, was crucified, died.” It is always one and the same Son of God, our Lord. Therefore it is certain that Mary is the mother of the real and true God, and that the Jews crucified not only the Son of Man but also the true Son of God. For I do not want a Christ in Whom I am to believe and to whom I am to pray as my Savior who is only man. Otherwise I would go to the devil. For mere flesh and blood could not erase sin, reconcile God, remove His anger, overcome and destroy death and hell, and bestow eternal life." (LW 24:106-107).

Conclusion
Here, Luther's using the rich Christ-centered usage of Theotokos (Mother of God) when discussing the incarnation or Christ’s Deity. I and conservative Protestant theology would agree with him.  This quote may be a "shocker" to fundamentalist types, but not to the Lutheran or Reformed. Notice that Luther mentions the Nestorians. I guess if Roman Catholic apologists are interacting with modern Nestorians that are fond of Luther, using this Luther quote could be useful.

When Rome's defenders bring up the phrase, "Mother of God," they have gone beyond what Luther usually means by it, attaching excessive veneration. What was once a rich theological term expressing a doctrinal truth about Christ developed into a venerating praise to Mary. If you agree to use this term in dialog with a Roman Catholic apologist, use it like Luther did. Use it to say something about Jesus Christ.
