In this episode, I sit down with Garrett Berk to explore a paper that he wrote on Augustine and the Pelagian controversy. Together, we delve into the historical backdrop of this pivotal conflict in the early church, examining how Augustine responded to the challenges posed by Pelagius and his followers. Our conversation traces the development of doctrine in the Western church, unpacking key theological shifts that still shape Christian thought today. We also consider the lasting influence of semi-Pelagianism in modern contexts and why these ancient debates continue to matter.
