Bread of Life
As the bread, which is produced from the earth, when it receives the invocation of God, is no longer common bread, but Eucharist, consisting of two realities, earthly and heavenly; so also our bodies, when they receive the Eucharist, are no longer corruptible, having hope of the resurrection to eternity.
–St. Irenaeus of Lyons
(AD 120-202)
