Whatever Marty said or thought doesn't enter into the equation. Ol' Pastor Scheer, (whom, I think actually knew Martin Luther...), was pretty positive that a strict interpretation of the Bible, In English, with a slant to the Trinity as separate and indivisible, plus a certain, shall we say, benign contempt for what he called "papists" (the selling indulgances guys), would pretty much cover all your bases. Plus, you had to wear a tie to church.
There was, I think, a two fingered, arm's length, face turned away tolerence for nancy boys, (sort of like holding an exceptionally full diaper), but he covered the 'Hate The Sin' half, without actually getting to the 'Love The Sinner' part...
And, to clarify my previous post, "strict" interpretation of the Bible does not indicate "literal."
Martin was more interested in arguing against the Church hierarchy's existing relationship with the people, rather than fencing about what angels could, or would, or whatever.
