When it comes to the study of theology, it can be tempting to reduce the things of God to mere intellectual exercises, arguing fine points of doctrine and speaking about faith in the abstract. But St. Irenaeus of Lyons reminds us that we are ultimately not judged simply on what we know, but on how we love God and love our neighbor. In this episode, Marcus Grodi and Msgr. Jeffrey Steenson explore how these themes play out in St. Irenaeus’ work Against Heresies.
