“We celebrate the memorial of the saving Passion of Your Son, his wondrous Resurrection and Ascension into heaven…”
When do we say this? After the consecration at every Mass. The Holy Eucharist recalls to our minds not just the Passion and death of our Redeemer, not just His conquest of death, but also His Ascension into heaven.
Now, the Mass Christ instituted recalls His Passion and death very vividly and clearly. His words declare His saving death: “My body will be given up for you.” “My blood will be shed for you.”
That said, the very same words of consecration declare His Resurrection as well. Because: He lives to give us His flesh and blood. If He were still dead, we could hardly receive Him bodily into our midst, in the Blessed Sacrament. We can have Mass because He is alive. Pretty clear.
Now, what about His Ascension? For our Ascension-tide theological question, let’s try to figure this one: How does the Holy Mass commemorate Christ’s Ascension?
Well, we could say this: The whole business of the Mass involves the celebration of Christ’s Passover. He passed over from life as a pilgrim to life in glory. Passed through death to eternal life. We cannot see the life that Christ the man shares with God. Our eyes do not now have the capacity to see that.
Which means that the Lord’s very in-visibility in the Mass commemorates His Ascension. He passed beyond our sight when He ascended, and He appears in a way that we cannot see at the consecration at Mass.
That said, Christ’s invisibility in the Mass is by no means absolute. If it were, we would celebrate Mass just by closing our eyes and looking at the inside of our eyelids. But we don’t do that.
At Mass, we see a sacrifice, carried out by a priest, with a priestly people united around the altar. All that is perfectly visible—and it is a visible manifestation of Christ, ascended into heaven. Because He ministers in heaven as our eternal High Priest, forever offering Himself, in perfect love, for us.
So: Holy Mass recalls Christ’s Ascension to our minds, both by what we don’t see, and by what we do.
