Also, this topic has been discussed basically at nauseum before, so some searching might be helpful. The classic model and antithesis is St. Cyprian of Carthage vs. St. Augustine
These might be helpful (or not...i didn't really read through them)
[Upon further thought, I decided that my link was not very helpful, but rather my statements below would be better than providing a random link - hence the edit]
If you do a search of the word "cyprian" you will get an assortment of topics, which may or may not help you.
If you search the word "salvation" you might get things more helpful, but there will also be A LOT MORE topics.
Good hunting! The more you read the bigger the picture you will get. Which is always helpful.
