If, however, being already regenerate and justified, he relapses of his own will into an evil life, assuredly he cannot say, "I have not received," because of his own free choice to evil he has lost the grace of God, that he had received. And if, stung with compunction by rebuke, he wholesomely bewails, and returns to similar good works, or even better, certainly here most manifestly appears the advantage of rebuke. But yet for rebuke by the agency of man to avail, whether it be of love or not, depends only upon God.Augustine says that so-in-so is "already regenerate and justifed" and yet "has lost the grace of God, that he had received." Because of his previous standing in the grace of God, the apostate can not say, "I have not received" regeneration, justification, and grace. Augustine explicitly says, "he has lost the grace of God, that he had received."
How much clearer does Augustine have to be? He states so clearly that the regenerate and justified person can lose the grace of God.
My suspicion is that "Jean Chauvin" will eventually one day become Catholic. Why? Two reasons. First, he protesteth too much. Second, he has started to read the Fathers of the Church. To be deep in history is to cease to be Protestant.
I once was an Calvinist who thought that he was merely being "Augustinian." However, when I started to read Augustine, I found that Augustine was a Catholic. I will soon publish some key quotes from Augustine's works that display his belief in Purgatory, the Sacrifice of the Mass, the Immaculate Conception of Mary, the Real Presence of Christ in the Eucharist, and even the propriety of praying to saints.
I hope that "Jean Chauvin" will stay tuned and see that St Augustine was a full out "Romish" priest, and not the Patristic Calvinist that he has been previously led to believe.
