With regard to the institution of this Sacrifice, the holy Council of Trent has left no with  room for doubt, by declaring that it was instituted by our Lord at His last Supper;  while it condemns under anathema all the those who assert that in it not offered to God  a true and proper Sacrifice; or that to offer means nothing less that that Christ is given as spiritual food. Nor did (the Council) omit carefully to explain that to God  alone is offered this Sacrifice. For although the Church sometimes offers Masses in honor and in memory of the Saints, yet she teaches that the Sacrifice is offered, not to them, but to God  alone, who has crowned the Saints with immortal glory. Hence the priest never says: I offer Sacrifice to Peter, or to Thee Paul;  but, while he offfers Sacrifice to God  alone, he renders Him thanks for the signal victory won the blessed martyrs, and thus implore their patronage, that they, whose memory we celebrate on earth, may vouchsafe to intercede for us in heaven.
