There is NO reason to step back.

You begin by cutting the ground out from under the very definition of truth.

And you make clear that will be result of your endeavor with "We both know full well that V1 used one of those pericopes as one of its core proof texts for the universal jurisdiction of the Bishop of Rome", when in fact that text has been used for nearly two thousand years just as it was used at Vaticans I and II.

Since the Church finds the revelation in both Scripture and Tradition, the observation that "beyond what we expect regard as the competence of scriptural scholars qua scriptural scholars" is meaningless, except that it also fails to note that scriptural scholars only have whatever authority the Church gives them, and none on their own.

I believe we're done.
