St. Augustine of Hippo was one of the brightest lights to emerge from Northern African Christianity during its first 500 years. St. Augustine became one of the most influential Christian theologians and philosophers in the history of the Church. Augustine's life and work profoundly impacted Western Christianity and philosophy. He was born on November 13, 354, in Tagaste (modern-day Souk Ahras, Algeria) in the Roman province of Numidia.
