For those who say that Paul's writings are in error or should not be in the Bible, consider that even as the rest of the New Testament was being written Peter already recognized Paul's writings as Scripture: II Peter 3:16 "as also in all his [Paul] epistles, speaking in them of these things, in which are some things hard to understand, which untaught and unstable people twist to their own destruction, as they do also the rest of the Scriptures." https://bible.com/bible/114/2pe.3.15-16.NKJV
