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. Otherwise, we make the same mistake as the devil himself.
