Sam, you really don't have too far to look; for there were many threads on this very subject over the last two years; primarily on Predestination, Augustine, and Calvinism...posted by Orthodox Presbyterian( formerly known as Uriel1975). Here is a link to the first thread that OP posted in January of 2000.

Please keep in mind that there are over 200 threads in this series..but if you thoughtfully read through the first 2-3 threads.. you'll get a good understanding of the Augustinian, or Calvinist Predestinarian position. You'll also get an earful from various people who fail to understand the underlying foundation..that God IS Sovereign. But..I think that you'll find that Uriel1975 (now Orthodox Presbyterian) eloquently presents the case for the Orthodox Biblical doctrine of Predestination.
I know that the concept of Predestination is a "toughie" to grasp; but it IS well worth anyone's time to examine.

BC, Sam's a friend of mine from The Hobbit Hole. I offer this warning as one who was chewed up and spit out in the Religion forum (yeah, I did a bit of my own as well). From my view, FR's Religion Forum is not the place for any serious study. If Sam really wants to understand Augustine and Calvin (and I believe he does), the religion forum is the last place I'd send him.
