We believe in the Resurrection of the Dead

Today we read of the hope of the Resurrection which sustained the 7 brothers who were matyred for their faith in and obedience to God (2 Macc 7). This reminded me of a passage from the Catechism of the Catholic Church (CCC):

654 The Paschal mystery has two aspects: by his death, Christ liberates us from sin; by his Resurrection, he opens for us the way to a new life. This new life is above all justification that reinstates us in God's grace, "so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life."⁵²⁶ Justification consists in both victory over the death caused by sin and a new participation in grace.⁵²⁷ It brings about filial adoption so that men become Christ's brethren, as Jesus himself called his disciples after his Resurrection: "Go and tell my brethren."⁵²⁸ We are brethren not by nature, but by the gift of grace, because that adoptive filiation gains us a real share in the life of the only Son, which was fully revealed in his Resurrection.
655 Finally, Christ's Resurrection - and the risen Christ himself is the principle and source of our future resurrection: "Christ has been raised from the dead, the first fruits of those who have fallen asleep. . . For as in Adam all die, so also in Christ shall all be made alive."⁵²⁹ The risen Christ lives in the hearts of his faithful while they await that fulfillment. In Christ, Christians "have tasted. . . the powers of the age to come"⁵³⁰ and their lives are swept up by Christ into the heart of divine life, so that they may "live no longer for themselves but for him who for their sake died and was raised."⁵³⁰
