Holy Thursday is the commemoration of the Last Supper of Jesus Christ, when he established the sacrament of Holy Communion prior to his arrest and crucifixion. It also commemorates His institution of the priesthood. Join us at this start of the summit of the Liturgical Year, Easter Triduum—from the evening of Holy Thursday to the evening of Easter Sunday. Though chronologically three days, they are liturgically one day unfolding for us the unity of Christ's Paschal Mystery.
