Christ lives in him when he is “crucified with Christ.” John Paul II notes that “Christ also becomes in a particular way united to the man, Paul, through the cross” (SD, 20).

In the Eucharist Christ gives us the very body which he gave up for us on the cross, the very blood which he 'poured out for many for the forgiveness of sins.' [Mt 26:28 .]" 1367.
