The REAL Reason Peter Plagiarized Jude . . . REVEALED!

Of the 25 verses in the epistle of Jude, 18 are copied in the letter of 2 Peter. How do we account for the massive similarities? There are three main theories.
1. There was a common source.
2. Jude copied Peter.
3. Peter copied Jude.
Peter expands upon ideas found in Jude; such as 2 Peter 2:12 and Jude 10, 2 Peter 2:1-3 and Jude 4.

Question: Isn't Jude 1:18 basically a quote from 2 Peter 3:3? They are almost identical and Jude says that it's a quote from an apostle (Peter being an apostle) but in his letter Peter doesn't quote it he just says it. Thoughts?

Wow, that's a really good point. That is extremely strong evidence that Jude was quoting Peter.
