yes, and those warnings appear in Deuteronomy and Revelation both. i think you misinterpret the passage from 2 Timothy, complete is an adjective describing the man of God, not describing the bible.

right so you can be complete, you don't need more than the Bible. How did I misinterpret it, I just posted the verse lol
your interpretation of the passage you quoted is the doctrine of sola scriptura. but that isn't how the majority of Christians over the last two millennia interpret it.
