"command that these gifts be borne by the hands of your holy Angel to your altar on high" (the Supplices te rogamus)

"with the pronouncement of the words of institution, the Sacrifice of the Mass is established [(acquis)], holy, approved; but this acceptation is only manifest for us at the moment in which the offering of our oblation appears transfigured in the fires of the Holy Spirit, transferred by the ministry of the angel onto the altar in heaven, fully conformed to the vivifying Body and Blood of Christ.  It is only then that, perfectly consecrated—Saint Gelasius and Saint Gregory said even simply consecrated—it can be divided [(rompue)] among all of those invited to the royal banquet of the Lamb."
