In a recent interaction between an agnostic and a Protestant, we see how truly cancerous (1) Sola Scriptura and (2) Protestantism are:
Steve McRae
(agnostic): But how would you come to the conclusion that Christ was the Son of
God if there wasn't ever this book that existed to tell you this?
Jonathan McLatchie
(Protestant): Well then, in that case, there would not in my opinion be
sufficient grounds for believing that proposition to be true. So, if there were
no Bible, then I wouldn't have sufficient grounds for believing it, and so I
wouldn't believe it. In fact, if there was no Bible, I would almost certainly
never have heard of Jesus. (Why I
Am / Am Not a Christian: Dr. Jonathan McLatchie & Steve McRae in Dialogue,
beginning at the 41:41 mark)
