Augustine's perspective was on single predestination of certain individuals. And the Church was in existance for 350 years or so before he wrote it. No assertion necessary.
Thankfully, the Reformation recovered the truth of Christ risen.
What? Was it hidden in a Dominican trunk somewhere and Calvin fetched it out? The Reformation was a complete innovation and did not resemble Christianity in any way, shape or form.
That is an error. Clearly, you may not have read Augustine's Treatise on the Predestination of the Saints or the many excerpts from it that have been posted on this thread.
If the truth actually mattered to Roman Catholics, they would read the works they're tossing around like popcorn.
Was it hidden in a Dominican trunk somewhere and Calvin fetched it out?
It may have been in a trunk, under lock and key by Rome. But thankfully, men were printing the Bible in a variety of languages and as men, Calvin included, began to read the Bible for themselves, the truth became clear.
Rome stood condemned by its error, as it does today.
