YOUCAT Question n. 221 - Part II. How does Holy Communion change me?

(Youcat answer – repeated) Every Holy Communion unites me more deeply with Christ, makes me a living member of the Body of Christ, renews the graces that I received in Baptism and Confirmation, and fortifies me for the battle against sin.   

A deepening through CCC

(CCC 1392) What material food produces in our bodily life, Holy Communion wonderfully achieves in our spiritual life. Communion with the flesh of the risen Christ, a flesh "given life and giving life through the Holy Spirit" (PO 5), preserves, increases, and renews the life of grace received at Baptism. This growth in Christian life needs the nourishment of Eucharistic Communion, the bread for our pilgrimage until the moment of death, when it will be given to us as viaticum.

(CCC Comment)

(CCC 1393) Holy Communion separates us from sin. The body of Christ we receive in Holy Communion is "given up for us," and the blood we drink "shed for the many for the forgiveness of sins." For this reason the Eucharist cannot unite us to Christ without at the same time cleansing us from past sins and preserving us from future sins: For as often as we eat this bread and drink the cup, we proclaim the death of the Lord. If we proclaim the Lord's death, we proclaim the forgiveness of sins. If, as often as his blood is poured out, it is poured for the forgiveness of sins, I should always receive it, so that it may always forgive my sins. Because I always sin, I should always have a remedy (St. Ambrose, De Sacr. 4, 6, 28: PL 16, 446; cf. 1 Cor 11:26).
