From Scripture. This answer is plainly backed by the text of Scripture.
Yes. Taught of Yah believes the apostles’ letters, including Paul’s, are Yahuah’s Word. They must be followed unless an apostle says otherwise in the text. These writings were given by Yahuah’s Spirit and are treated as Scripture.
“even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; As also in all his epistles… which they that are unlearned and unstable wrest, as they do also the other scriptures” (2 Peter 3:15-16).
“All scripture is given by inspiration of God” (2 Timothy 3:16).
