[Petronski]

Paul is saying that scripture extant at a time around 64AD was necessary and sufficient to bring a person to salvation, complete and fully equipped for every good work.

You're little theory here is that Paul isn't saying "sola scriptura," but more specifically, "sola scriptura ante-64AD."

Thus, your theory must be false, for it suggests that the New Testament WITHOUT ANY OF THE FOUR GOSPELS is necessary and sufficient blah blah blah.

Absurd.

[Chaguito]

Like I said, your responses are like papal bulls. So...authoritative.
