Marcus Grodi and Msgr. Jeffrey Steenson continue their study of "Against Heresies" by early Church father St. Irenaeus of Lyons.

Christians are called to build a civilization of God's love on the earth. But it is impossible to live this love of God and love of neighbor on our own; we must live it in the unity of the Church that Christ established and continues to sustain.

St. Irenaeus of Lyons reminds us that God's vision for His people was given through families in the Old Covenant, and that God's family continues today in the Church.
