This is a carry-over from another thread, which I wouldn’t comment on in that thread because it was off topic. I also felt I was being asked to represent all Protestants as well as to defend Martin Luther. I thought I made it clear that I cannot and will not speak for all Protestants. Furthermore, since I am not a Lutheran (which I pointed out), I feel no need to defend anything he did.
As far as the “canon” (why all the "'s?), I will agree with St. Jerome’s Old Testament canon, which is what the Protestant bibles contain (see
here). While he translated the deuterocanonicals and included them in his Latin Vulgate (he didn’t want to, but was told to), he did not consider them inspired Scripture I find it interesting that Cardinal Cajetan (the fellow that interviewed Martin Luther) also agreed with St. Jerome (see
here).
