I've read several books on the NT canon lately, and most scholars do not think several of Paul's letters were written by him. 2 Peter, they say, was written not by Peter but by a pseudonymous author around A.D. 150. So how important is authorship to the integrity of our NT canon? I don't think 2 Peter is pseudonymous, but many people do. If it were a mid-second century pseudonymous work, though, would that lessen the integrity of our canon? How important is it that our Bible was written by apostolic figures? Were apostolic figures around in the mid-second century and capable of writing Scripture?
