Oh, that you were correct, verga. But alas. The Scripture you speak of is 2 Tim. 1:13. This Epistle is the last Epistle from Paul, as he says he is “Now ready to be offered.” 4:6. THis would be around 67 AD. Which means the Church had ALL of Paul’s writings when this arrived. His writings were complete. Peter calls Paul’s writings Scripture in 2 Pet. 3:16. SO, ALL of Paul’s writings were no longer traditions the believers were taught. They were WRITTEN Scriptures. As a matter of fact, anything written before Paul’s martyr were not merely “oral tradition” passed along. The scriptures Paul was talking about were not only the OT but HIS own writings. As confirmed by Peter.
Paul was referring only to the OT. Do you honestly think he considered his writing sacred. they were not part of the accepted Canon until the late 300's
