Oral teaching is not tradition.
Tradition is what is passed down from one generation to the next.
Verbal, oral, teaching can be done right from Scripture itself and does not automatically become tradition by virtue of the fact that it is spoken.
The Catholic church is great at denigrating Scripture and attacking its integrity.
Did God really say....?????
Tradition is what is passed down from one generation to the next.
And how do you suppose it was passed down? Orally.
