Let me add this about 4 point cal's.

Way back in Seminary I had a friend who claimed 4pts. However, through discussing the issue he just re-defined the terms. All said and done, he did not even agree with Total Depravity (though he claimed he did). And since then, when I run accross those who claim's 3 or 4 points, I often find the same result.

Being a Baptist in the deep south, I am sorry to guess that 3/4 of the other ministers that I have the occation to talk even about Perserverence do not even hold this doctrine as stated in the 1689 confession.
