However, the way to the interior life as well as to the choirs of blessed spirits who sing the eternal Sanctus is Christ.
His blood is the curtain through which we enter into the Holiest of Holies, the Divine Life. In baptism and in the sacrament of reconciliation, his blood cleanses us of our sins, opens our eyes to eternal light, our ears to hearing God’s word.
It opens our lips to sing his praise, to pray in expiation, in petition, in thanksgiving, all of which are but varying forms of adoration, i.e., of the creature’s homage to the Almighty and All-benevolent One.
In the sacrament of confirmation, Christ’s blood marks and strengthens the soldiers of Christ so that they candidly profess their allegiance.
However, above all, we are made members of the Body of Christ by virtue of the sacrament in which Christ himself is present.
When we partake of the sacrifice and receive Holy Communion and are nourished by the flesh and blood of Jesus, we ourselves become his flesh and his blood.
And only if and insofar as we are members of his Body, can his Spirit quicken and govern us. “It is the Spirit that quickens, for the Spirit gives life to the members. But it only quickens members of its own body…. The Christian must fear nothing as much as being separated from the Body of Christ. For when separated from Christ’s Body, the Christian is no longer his member, is no longer quickened by his Spirit….”
However, we become members of the Body of Christ “not only through love…, but in all reality, through becoming one with his flesh: for this is effected through the food that he has given us in order to show us his longing for us.
“This is why he has submerged himself in us and allowed his body to take form in us. We, then, are one, just as the body is joined to the head…..”
As members of his Body, animated by his Spirit, we bring ourselves “through him, with him, and in him” as a sacrifice and join in the eternal hymn of thanksgiving.
Therefore, after receiving the holy meal, the church permits us to say: “Satisfied by such great gifts, grant, we beseech you, Lord, that these gifts we have received be for our salvation and that we never cease praising you.”
