2 Timothy 3:14-17
14 But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;
15 And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.
16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17 That the man of God may be perfect, thoroughly furnished unto all good works.
Scripture is all that is needed to be “PERFECT and thoroughly furnished unto ALL good works.” The Word of God is sufficient.
That is all true, but it does not say that the Bible ALONE is the source of our Teaching. And you have not shown me anything about the Bible stating that it is the pillar of truth for us.
