“67. Christ the Lord, ‘Eternal Priest according to the order of Melchisedech’ (Psalm109:4), ‘loving His own who were of the world’ (John 13:1), ‘at the Last Supper, on the night He was betrayed, wishing to leave His beloved Spouse, the Church, a visible sacrifice such as the nature of men requires, that would re-present the bloody sacrifice offered once on the cross, and perpetuate its memory to the end of time, and whose salutary virtue might be applied in remitting those sins which we daily commit, . . . offered His Body and Blood under the species of bread and wine to God the Father, and under the same species allowed the Apostles, whom He at that time constituted the priests of the New Testament, to partake thereof; commanding them and their successors in the priesthood to make the same offering’ (Council of Trent, Sess. 22, c. 1).

“70. Likewise the victim is the same, namely, our divine Redeemer in His human nature with His true body and blood. The manner, however, in which Christ is offered is different. On the cross He completely offered Himself and all His sufferings to God, and the immolation of the victim was brought about by the bloody death, which He underwent of His free will. But on the altar, by reason of the glorified state of His human nature, ‘death shall have no more dominion over Him’ (Romans 6:9), and so the shedding of His Blood is impossible; still, according to the plan of divine wisdom, the sacrifice of our Redeemer is shown forth in an admirable manner by external signs which are the symbols of His death. For by the ‘transubstantiation’ of bread into the Body of Christ and of wine into His Blood, His Body and Blood are both really present: now the Eucharistic Species under which He is present symbolize the actual separation of His Body and Blood. Thus the commemorative representation of His death, which actually took place on Calvary, is repeated in every Sacrifice of the Altar, seeing that Jesus Christ is symbolically shown by separate symbols to be in a state of victimhood.”
