Christians, would you buy this NT?

[Aractus]

- 2 Corinthians is actually 4 or 5 letters and one of them isn't from Paul

There's no doubt that Paul wrote 2 Corinthians, and the hypothesis that it is composed of multiple letters from Paul is just speculative there's no real evidence for that.

- Sections of the gospels that were probably added later would be eliminated

The added sections, including the part you mentioned regarding handing serpents in Mark, have been eliminated through textual criticism. Only the Orthodox and conservative Catholics keep them. Anyone who believes in textual criticism removes them.

- 2 Peter, 2 John, and 3 John would be eliminated as forgeries

2 Peter would be removed, so too probably would 1 Peter. There's no reason to remove 2 and 3 John because a majority of scholars believe all three epistles 1, 2, 3 John to be written by the one author.

Interesting that you had nothing to say about Jude, James, or Revelation.

If 2 Peter pre-dates Jude then you'd have to eliminate Jude. But that's by no means a settled theory, and it could well be that 2 Peter used the book of Jude, which would lend credibility to its authenticity.

You would not want to keep Revelation though since its content is unverifiable.
