I too will proclaim the greatness of this day: the Immaterial become incarnate, the Word is made flesh, the invisible makes itself seen, the intangible can be touched, the timeless has a beginning, the Son of God becomes the Son of Man, Jesus Christ, always the same, yesterday, today and forever. . This is the solemnity we are celebrating today: the arrival of God among us, so that we might go to God, or more precisely, return to Him. . Revere the nativity which releases you from the chains of evil. Honor this tiny Bethlehem which restores Paradise to you. Venerate this crib; because of it you who were deprived of meaning (logos) are fed by the divine Meaning, the divine Logos Himself.
