Christ Our Pascha: Catechism of the Ukrainian Catholic Church

215 The word Pascha, derived from the Hebrew, Pesach, means to pass by, to pass through. The Pascha of Jesus Christ is his
passing through suffering and death to his glorification in the Resurrection and Ascension. In the deepest sense, Christ himself is the Pascha (Passover) (see 1Cor 5:6-8), for the passage from death to life takes place in him: “Pascha, Pascha of the Lord, for from death to life, and from earth to heaven Christ God has led us.” 174 Without him, all the efforts of the human race to free itself from slavery to sin and death would be in vain.
