Unverifiable

I have been told the following Luther quote is unverifiable.

“If I profess with the loudest voice and clearest exposition every portion of the Word of God except precisely that little point which the world and the devil are at that moment attacking, I am not confessing Christ, however, boldly I may be professing Him.  Where the battle rages there the loyalty of the solider is proved; and to be steady on all the battle front besides, is mere flight and disgrace if he flinches at that point.”

I was told that although this has been attributed to Luther for many years no one has been able to cite where.  In cleaning out files, I find the above and it is cited “(Luther’s Works, Weimar Edition, Briefwechsel [Correspondence], vol. 3, pp. 81f.)”

I don’t have the Weimar edition; come to think of it couldn’t read it if I did.  If someone does and can, if they would prove or disprove the citation, I would be grateful.

A reader has lately provided the following:

That’s a page from Sämtliche Werke (Collected Works), v. 53, with this exact paragraph in it.  I don’t know if that’s *proof* that he wrote it, but it’s something anyway.  It’s on p.171 of Vermischte Deutsche Schriften, 1. Band.
