June 28 is the traditional date (in the west) to commemorate the death of Irenaeus of Lyons, who died sometime around AD 202. One of the most important early theologians of the Christian church, Irenaeus is best known for his Against Heresies, a lengthy refutation of gnosticism, which was one of the major challenges to orthodox Christianity at the time.
In memory of Irenaeus, here are two prayers that are commonly attributed to him. I have not been able to track down the original location of either prayer, or even verify that they are in fact his. So, if anyone has any information about these prayers, please let me know.
O Lamb of God, who takest away the sin of the world,
look upon us and have mercy upon us;
thou who art thyself both victim and Priest,
thyself both Reward and Redeemer,
keep safe from all evil those whom thou hast redeemed,
O Savior of the world.
It is not you that shapes God
it is God that shapes you.
If you are the work of God
await the hand of the artist
who does all things in due season.
Offer Him your heart,
soft and tractable,
and keep the form
in which the artist has fashioned you.
Let your clay be moist,
lest you grow hard
and lose the imprint of his fingers.
