Marcus Grodi and Msgr. Jeffrey Steenson continue their study of Against Heresies, the important early Christian work by St. Irenaeus of Lyons.

Among other things, they look at how St. Irenaeus speculated about the identity and plan of the Antichrist. Just as in our present day, there were many differing opinions among the early Christians about how the end times might play out.

Marcus and Msgr. Steenson look not just at what St. Irenaeus has to say about the Antichrist, but at why it's important for us to always be ready for Christ's ultimate return, because we don't know if it will happen today, or a thousand years from now.
