Life

A disciple of Polycarp, who was a disciple of John — Irenaeus carried the apostolic memory from Smyrna to Gaul, where he became bishop of Lyons after its martyrs’ deaths. His name means ‘peacemaker,’ and he lived it in the Church’s disputes.

His great work Against Heresies dismantled Gnosticism by appealing to the public, apostolic faith of the churches. He taught that the glory of God is a living man, and that the life of man is the vision of God.

In their own words

Each quotation names the work it comes from. Bless quotes these in the comments beside the verses listed under In Scripture.

The glory of God is a living man; and the life of man consists in beholding God.

Against Heresies, IV.20.7, c. 180

The Word of God became what we are, that He might make us what He Himself is.

Against Heresies, III.19.1, c. 180

Our bodies, receiving the Eucharist, are no longer corruptible, having the hope of the resurrection to eternity.

Against Heresies, V.2.3, c. 180
