“We should understand, beloved, that the paschal mystery is one once old and new, transitory and eternal, corruptible and incorruptible, mortal and immortal. In terms of the Law is it old, in terms of the Word it is new. In its figure it is passing, in its grace it is eternal. It is corruptible in the sacrifice of the lamb, incorruptible in the eternal life of the Lord, It is mortal in his burial in the earth, immortal in his resurrection from the dead.

Easter Homily by St. Melito of Sardis
