As I've explained to other Protestant posters earlier last week, until you can prove BIBLICALLY that "Sola Scriptura" is Biblical, I am not bounded to prove it using that reasoning. We know these things from historical records outside of the Canon of Scripture, and no reputable source argues to the contrary.
This still has nothing to do with the topic of the thread.
You're right it doesn't, it kinda got a little off topic in this thread.
We are no more bound to prove something based upon the false teaching of "sola scriptura" than we are bound to prove something based on the Koran.
