"If the 'teaching' supports the Apostolic tradition then that teaching is correct."

You still come down to the same old problem in the final analysis - WHO decides whether any teaching supports the Apostolic tradition?

Also beware Tertullian - many of his writings date from his semi-Montanist and Montanist periods. The Montanists rejected the inspired nature of the OT, which doctrine, needless to say, was not part of the Apostolic tradition.

Do you know which writing that quote from Tertullian comes from?

Simply, those teachers and theologians who strictly adhere to the rule of Faith. The RCC gave up that right when it added non-apostolic tradition to the rule of Faith.
