Sacramentum Caritatis §8

A free gift of the Blessed Trinity

8. The Eucharist reveals the loving plan that guides all of salvation history (cf. Eph 1:10; 3:8- 11). There the Deus Trinitas, who is essentially love (cf. 1 Jn 4:7-8), becomes fully a part of our human condition. In the bread and wine under whose appearances Christ gives himself to us in the paschal meal (cf. Lk 22:14-20; 1 Cor 11:23-26), God's whole life encounters us and is sacramentally shared with us. God is a perfect communion of love between Father, Son and Holy Spirit. At creation itself, man was called to have some share in God's breath of life (cf. Gen 2:7). But it is in Christ, dead and risen, and in the outpouring of the Holy Spirit, given without measure (cf. Jn 3:34), that we have become sharers of God's inmost life. (16) Jesus Christ, who "through the eternal Spirit offered himself without blemish to God" (Heb 9:14), makes us, in the gift of the Eucharist, sharers in God's own life. This is an absolutely free gift, the superabundant fulfilment of God's promises. The Church receives, celebrates and adores this gift in faithful obedience. The "mystery of faith" is thus a mystery of trinitarian love, a mystery in which we are called by grace to participate. We too should therefore exclaim with Saint Augustine: "If you see love, you see the Trinity." (17)
