St. Augustineās work on predestination was apologetic - i.e., he was defending the orthodox position against tweo heresies: Pelagianism and Semi-Pelagianism. These, basically, maintained that a personās salvation is completely up to that individual - that how that individual chooses to live determines his salvation or damnation. In other words, that God provides the means to heaven (or hell) but which one a person gets is completely up to that person. In combatting this, St. Augustine emphasized Godās complete sovereignty. According to Augustine (as mentioned in the New Catholic Encyclopedia (N.C.E.)]), āpredestinationā (or āforeknowledgeā) in God has to do with Godās sovereign will in the matter of salvation. Soā¦apart from God, no one can be saved. āAccording to St. Augustine, the decrees of the divine will are infallible regarding predestination ⦠because He is omnipotent and accomplishes what He willsā (N.C.E.). Taken aprt from the rest of his works, Augustineās treatment of predestination can seem to mean that salvation or damnation are āexclusivelyā Godās prerogative aprt from our own free response. This isnāt what he meant - else all of his own sermons were quite pointless!
St. Thomas said, agreeing with Augustine on this point, that Godās choice / will is His own, caused in no way by any creature. The result of our choices in response to Grace from God is 1] a consequence of our free will; and 2] 'foreāknown (predestined) by God. But it isnāt āorderedā (in the sense of ācommandedā) by God. Thomas built upon what Augustine said, but - not being embroiled in an ongoing defense against a popular heresy on the issue, as Augustine was - took the study of the matter deeper and further.
The Catholic Church maintains - dogmatically - the following:
God āpredestinesā NO ONE to evil;
He wills that everyone be saved;
Christ died for everyone - not only for those whom he foreknows as āsavedā;
Grace to be saved is truly sufficient for salvation AND a gratuitous (freely given) gift of God;
The grace to be saved is offered to sinners;
Those who are damned are deprived of salvific grace by their own refusal of it, and this refusal IS NOT caused by God, but He allows it.
