A8: Yes.
The issue here presented gets at the type and amount of error required for separation — an enquiry which is related to the first mark as we need to consider the content of the truth of the Word of God. They are two different positions on this issue: the confessional maximalist (Reformed) or the confessional minimalist (Evangelical). Historically speaking, both positions will present the same answer to Frank’s question, since one of the proof texts used to support Purgatory (2 Macc. 12:42-45) is in the Apocrypha.
However, if we remove Trent from its historical context and merely ask whether an insistence to add uninspired books to Scripture is reason to separate from a church, then I will not presume to speak for the Confessional Minimalist. As a Confessional Maximalist, I would still say that such necessitate separation because a good and necessary consequence (WCF Chapter 1, Section 6) of the Gospel message means that the grounds of its authority (the Scriptures) is just as important for the Church as the Gospel.
This is centuri0n, aka Frank Turk, who has been an internet apologist for about 10 years and has never really gained anything for himself through it but a handful of friends and a lot of ill-will. Most people, honestly, do not like to argue with him because he doesn't know how to let it go. He's a blogger of some minor note, and he's a "calvinist".
