Saint Augustine is one of Christianity’s most influential figures, and yet his path to sainthood was wayward. For his first 30 years, Augustine studied rhetoric, Gnosticism, and philosophy, all the while indulging in lust and greed. He struggled to understand the nature and world of God.

Fox joins us Monday to discuss Augustine’s journey from conversion to The Confessions.
