Your source makes a distinction between “removing” books from the bible, and deeming them non-canonical. Yes, I’ll concede that Luther continued to publish them in the same volume as the rest of the bible... in exactly the same manner as which he published the Old Testament deuterocanonicals. Since I also described this practice as “removing” in the case of the Old Testament deuterocanonicals, any attempt to quibble with my description regarding the New Testament deuterocanonicals is semantical nonsense: the only point is that Luther vehemently claimed that they were not sacred scripture. And as to the assertion that Luther regarded them as beneficial to be read, one must also read the vehemence which he objected to them; if they lead one to soul-destroying doctrinal error, how can they be beneficial? Luther is merely trying to have it both ways as he described Jerome doing, but since he held opinions he could never attribute to Jerome, doing so was merely talking out of both sides of his mouth, as he was very prone to do. (Read him in reference to antinomianism, or his ecclesiology with reference to the Peasant’s Massacre.)
Do you know of any Protestant denomination that rejects any of the books of the New Testament? Whatever Luther’s feelings were, and they were NOT as opposed to certain books as you make out - he was writing as a scholar and not as a Pope. he included ALL the New Testament, and all the New Testament is accepted by every Protestant denomination I know of.
For example, Luther wrote this on Hebrews:
““[I]t is still a marvelously fine epistle. It discusses Christ’s priesthood masterfully and profoundly on the basis of the Scriptures and extensively interprets the Old Testament in a fine way, Thus it is plain that this is the work of an able and learned man; as a disciple of the apostles he had learned much from them and was greatly experienced in faith and practiced in the Scriptures. And although, as he himself testifies in chapter 6[:1], he does not lay the foundation of faith—that is the work of the apostles—nevertheless he does build well on it with gold, silver, precious stones, as St. Paul says in I Corinthians 3[:12]. Therefore we should not be deterred if wood, straw, or hay are perhaps mixed with them, but accept this fine teaching with all honor; though, to be sure, we cannot put it on the same level with the apostolic epistles.”[109]”
He also preached from it regularly.
