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.

Marcus Grodi and Msgr. Jeffrey Steenson continue to work their way through Against Heresies by St. Irenaeus of Lyons, one of the most important witnesses from the earliest days of Christianity.

St. Irenaeus reminds us that theological opinions that appeal to our pride put us in the same camp as Lucifer himself, who fell from heaven because he thought he knew better than what he had been taught. It can be easy to fall into philosophies that stoke our egos, but St. Irenaeus emphasizes the need for humility, and to serve God rather than our own interests when seeking after the truth.

Marcus Grodi and Msgr. Jeffrey Steenson continue their journey through the 2nd century Christian work Against Heresies by St. Irenaeus of Lyons.

St. Irenaeus reflects on Original Sin, and its implications for salvation history, all the way up to the temptation of Christ himself. Satan has always sought to disrupt God's plan, and especially to ruin humanity, the crown of God's creation. But that old original enmity between God and Satan, even though it appears to be a conflict in progress to us who are alive, is a victory that no one but God can possibly win in the end.

God comes to save both our souls and our bodies together, and we must bring both into union with God now so as to enjoy communion with Him, body and soul, for all eternity.
