Paul isn’t a false teacher, he’s just very difficult (remember, he was converting Pharisees, who were a bit like Lawyers), and easy to misconstrue from our lacking modern contexts and translations.

Paul, as taught, is false (edit: in parts). Jesus, as recorded, is very straightforward, but ignored in favor of misunderstanding Paul. I don’t claim to understand why.

2 Peter 3:15-16 - 15 And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; 16 As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest (as they do also the other scriptures) unto their own destruction.

I.e. People take Paul out of context, leading to their own destruction, but this is also not unique to Paul. I may have taken another verse out of Biblical context, via poor translation, earlier today even myself - it is important to always test things.
