Happy Ascension Thursday!

...and a cloud took him out of their sight. (Acts 1:9)

The Catechism of the Catholic Church, paragraphs 670-671:

Since the Ascension God's plan has entered into its fulfillment. We are already at "the last hour". Already the final age of the world is with us, and the renewal of the world is irrevocably under way; it is even now anticipated in a certain real way, for the Church on earth is endowed already with a sanctity that is real but imperfect. Christ's kingdom already manifests its presence through the miraculous signs that attend its proclamation by the Church.

Though already present in his Church, Christ's reign is nevertheless yet to be fulfilled "with power and great glory" by the King's return to earth. This reign is still under attack by the evil powers, even though they have been defeated definitively by Christ's Passover. Until everything is subject to him, "until there be realized new heavens and a new earth in which justice dwells, the pilgrim Church, in her sacraments and institutions, which belong to this present age, carries the mark of this world which will pass, and she herself takes her place among the creatures which groan and travail yet and await the revelation of the sons of God." That is why Christians pray, above all in the Eucharist, to hasten Christ's return by saying to him: Marana tha! "Our Lord, come!"
