WRONG.
The essence of the Scriptures supporting God's Word alone as a RELIABLE AND SUFFICIENT foundation, source of God's truth are fairly straight-forwardly written.
There are NONE supporting TRADITIONS AND DOCTRINES OF MEN AND SEVERAL SCRIPTURES SCREAMINGLY HOSTILE TO THE WHOLE IDEA OF VALUING TRADITIONS AND DOCTRINES OF MEN IN THE SLIGHTEST POSITIVE LIGHT.
Name one such verse or I will be forced to conclude that you simply are bluffing, and that you have no such verses.
