Catechism of the Catholic Church

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." 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" 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." (989, 1002)
