[Polycarp IV]

The Apostles said to stick with the teachings that we have read [= SCRIPTURE-namely, the Old Testament, since the New Testament was not yet in written form, it was only in oral tradition]and have heard [heard= ORAL TRADITION, definitely NOT written scripture.] There are no more Apostles so I need to stick with what I can read. Sola Scriptura. QED!

Oh my, doesn't it hurt your pretty little head to be so publicly confused? Which is it you follow? Only the Old Testament Scripture, or Scripture plus the teachings they have heard, i.e., Apostolic Tradition?

[Tao Yin]

He was talking about the letters. As in the New Testament. They were not talking about the Old Testament. You are soundly confused.
