Holy Thursday

The liturgical celebration of the Lord’s Supper on Holy Thursday is not merely the annual remembrance of the institution of the sacrament of Holy Communion. Indeed the very event of the Passover Meal itself was not merely the last-minute action by the Lord to “institute” the central sacrament of the Christian Faith before His passion and death. On the contrary, the entire mission of Christ, and indeed the very purpose for the creation of the world in the first place, is so that God’s beloved creature, made in His own divine image and likeness, could be in the most intimate communion with Him for eternity, sitting at table with Him, eating and drinking in His unending kingdom. Thus, Christ the Son of God speaks to His apostles at the supper, and to all men who hear His words and believe in Him and the Father who sent Him.
