>>It never says "disregard the Oral Tradition (preaching of the Apostles): neither listen to us nor imitate us; accept nothing from us unless it's in print."<<
Paul did say if anyone taught something they didn't that teacher was to be considered accursed though didn't he.
I would never dare --- and the Catholic Church would never dare --- to teach something unambiguously slap-down forbidden by St.Paul.
But Paul said to be faithful to his spoken word, his example, and his letters --- correct?
