CCC 638

"We bring you the good news that what God promised to the fathers, this day he has fulfilled to us their children by raising Jesus." Acts 13:32-33. The Resurrection of Jesus is the crowning truth of our faith in Christ, a faith believed and lived as the central truth by the first Christian community; handed on as fundamental by Tradition; established by the documents of the New Testament; and preached as an essential part of the Paschal mystery along with the cross:

Christ is risen from the dead! Dying, he conquered death; To the dead, he has given life. Byzantine Liturgy, Troparion of Easter.
