Find it hard to get your head around Calvinism, Armenianism, Original Sin, Predestination and other focal points of Augustinian theology? Try simplifying things by shifting your focus to much earlier in history -- the time of Irenaeus.
Mind you, St. Augustine was a deserving of the honour of sainthood. His dedication and devotion to God are exemplary, and his testimony of his conversion is a great inspiration. The story of his mother's dedication and unceasing prayer is especially inspiring.
But his Bible teaching....?
St. Augustine lived in the fourth century, was heavily influenced by his Greek style education -- though he never learned the Greek language. In other words, he based his theology on the Latin scriptures (with all their translation errors), and used his Greek style reasoning to interpret it. Many of the doctrines that he passed down to us, we are hard put to find in the writings of earlier Church Fathers.
St. Irenaeus, on the other hand, lived in the second century. He was well versed in the Greek scriptures in their original (or closer to the original) texts, but interpreted it in the Hebraic style rather than Greek. In fact, he was the pupil of St. Polycarp, who was the pupil of St.John.
A great piece of work is St. Irenaeus' THE PROOF OF THE APOSTOLIC PREACHING. He goes systematically through what the early believers had received directly from the Apostles. Free will vs determinism wasn't even a question yet. Original Sin isn't mentioned, nor alluded to. Instead, the emphasis is on death and resurrection. Sin -- or disobedience -- resulted in death. Jesus came to bring life, and the resurrection.
Overall, you'll be edified by a challenge to walk the life of faith, worded in the simple language of the earliest believers.
