some can’t accept it, but St Augustine was thoroughly Catholic in his theology. i won’t even get into his teaching on purgatory, confession, and prayers to the saints, their head might explode!!
Augustine was just a man. He was correct on some points and not on others, according to how faithful he was to the word of God.
But Roman Catholics tend to look to the young, early Augustine and ignore the fact that Augustine’s faith matured, leaving behind many of the trappings of what would later consume the church in Rome.
They also ignore the fact Augustine was thoroughly a predestinarian who believed God elected for His own good reasons and not according to men’s good works.
Augustine was a Christian. He wasn’t a Roman Catholic.
