Of course, my point is that the Protestant Bereanism if I can coin the term, is not sufficient for maintaining proper doctrine and teaching.
I think this was your point: Sola Scriptura and testing against the scriptures is the primary requirement for right doctrine and right teaching.
My response was to show that in your own opinion, it's not. There must be something more required, yes?
Wrong. From Scripture, I can tell you that Benny Hinn, Jack Van Impe, and Kenneth Copeland are false prophets and should be shunned. Sola Scripture and Bereanism work just fine here. I never made a claim that there weren't heretics masquerading as protestants. We know that they are aberant, however, by comparing what they say with Scripture- just like the Bereans.
