Marcus Grodi and Msgr. Jeffrey Steenson continue to make their way through Book 3 of Against Heresies by the 2nd century Christian writer St. Irenaeus of Lyons.

They look at any evidence for dispensational and covenantal theology in St. Irenaeus, the importance of Jerusalem and Rome as centers of Christian heritage, and more thoughts on why Christians should look to the apostles rather than the Gnostics when trying to understand the Gospels.
