TurretinFan is much more gracious than I am. He's been going through Steve Ray's 35 loaded Questions for "Bible Christians" (PDF alert). TurretinFan came upon #30:
30) If the Bible is as clear as Martin Luther claimed, why was he the first one to interpret it the way he did and why was he frustrated at the end of his life that “there are now as many doctrines as there are heads”?
TFan did a great job of locating a very similar Luther quote, via a book by Joseph Lortz:
The whole history of philosophy and religion, of Christian heresies, and finally of the Reformation itself, is convincing proof of a statement that Luther himself affirmed in his First Lecture on the Psalms: “Unless doctrine is authoritatively promulgated by a living human being endowed with the authority to teach, there will be as many doctrines as there are heads.” Joseph Lortz, The Reformation: a problem for today (Newman Press, 1964), p. 246
In his lecture on the Psalms (about 1512), he had said: “Unless doctrine can be authoritatively guaranteed by one living man, there will be as many doctrines as there are men.” Joseph Lortz, The Reformation: a problem for today (Newman Press, 1964), p. 149
I say TFan is more gracious, because he says, "I'm quite sure Steve Ray cannot give an accurate citation for that alleged quotation from Luther." I'd go a bit further, and say Steve Ray probably doesn't even know what a "Lortz" is. In fact, I'd speculate that Ray (or David Palm, if it was his question) actually was using a different Luther quote, but cited it incorrectly (see this link also).
As TFan points out, if indeed these men are using the same quote Lortz is referring to, it's a pre-Reformation quote, not a quote from the end of his life, and it has nothing to do with Luther being "frustrated." But if my suspicion is correct, the botched quote they are using is from 1525: not the end of his life either. So, when Ray says,"frustrated at the end of his life," this was just added on for propaganda purposes. Either scenario demonstrates the question is bogus.
It is true that Luther lamented the rise of sects, as well as sects within Romanism. But Luther doesn't blame the perspicuity of Scripture, nor does his blame sola scriptura. He blames Satan and sin. He fully expected the Gospel to cause divisions. He fully expected the preaching of the Scriptures to be attacked by those misusing it.
If any of you haven't read TFan's critique of Ray's 35 Loaded Questions, I strongly suggest you begin doing so. The questions are loaded alright: their loaded with errors, and I doubt we'll see any serious responses by Mr. Ray to TFan's analysis.
One final irony: Steve Ray sells the Collected Works of Martin Luther on his website, I kid you not. I suggest perhaps he buy this product from himself and at least cite things accurately.
