Marcus Grodi and Msgr. Jeffrey Steenson resume their discussion of “Against Heresies” by St. Irenaeus of Lyons by continuing through Book 12.

They look at what St. Irenaeus had to say about natural law, and the order with which God established His creation. The incarnation of Jesus does not contradict either the natural law that is common to all humanity, nor the revealed law given through Moses; rather, it fulfills both the natural and reveal law and shows God’s plan for His people.
