Read Reformed Not At All and you will see he does deny Justification By Faith Alone from his own book.
Well then he is a heretic and this was Robin's point that FVers are neo-galatians. He used another term that he coined and I cannot think of it off the top of my head.This is why FV becomes so dangerous because it is a denial of the gospel.
While I firmly disagree with FV, I have trouble reading Robbins' stuff since the same man said Van Til denied the Trinity. So if we are calling someone a damnable heretic, and it comes from Robbins, forgive me if I take it with a grain of salt.
And yes, I do listen to John Robbins' lectures for profit on other topics.
Do you have a reference to his accusation that VanTil denied the Trinity because I have been on his mailing list and have never heard this before? I agree with you that he is not VanTillian but he is presuppositional. Robbins holds to the teachings of Gordon's Clark and certainly would oppose VanTil.
This is why FV becomes so dangerous because it is a denial of the gospel.

Heretics are usually those too smart for most of us. I ain't clever enough for their sophistries.
