Who was Augustine of Hippo?
Augustine (354–430 AD) was a North African bishop and the most influential theologian of the early church. His works on grace, sin, free will, the Trinity, and the church shaped Western Christianity for over 1,500 years.
Converted dramatically as an adult ("take up and read"), Augustine recorded his journey in the Confessions — the first great Christian autobiography.
Major works: City of God, On Christian Doctrine, On the Trinity, and writings against the Pelagians on grace and original sin.
Both Catholic and Reformed theology trace deep roots to Augustine. Reading him still pays — sin is real, grace is sovereign, our hearts are restless until they rest in God.
