Sacramentum Caritatis §36

The eucharistic celebration, the work of "Christus Totus"

Christus totus in capite et in corpore

36. The "subject" of the liturgy's intrinsic beauty is Christ himself, risen and glorified in the Holy Spirit, who includes the Church in his work. (109) Here we can recall an evocative phrase of Saint Augustine which strikingly describes this dynamic of faith proper to the Eucharist. The great Bishop of Hippo, speaking specifically of the eucharistic mystery, stresses the fact that Christ assimilates us to himself: "The bread you see on the altar, sanctified by the word of God, is the body of Christ. The chalice, or rather, what the chalice contains, sanctified by the word of God, is the blood of Christ. In these signs, Christ the Lord willed to entrust to us his body and the blood which he shed for the forgiveness of our sins. If you have received them properly, you yourselves are what you have received." (110) Consequently, "not only have we become Christians, we have become Christ himself." (111) We can thus contemplate God's mysterious work, which brings about a profound unity between ourselves and the Lord Jesus: "one should not believe that Christ is in the head but not in the body; rather he is complete in the head and in the body." (112)
