Missa Gregoriana no Mundo . BEAT0 CARLO ACUTIS: Holy Sacrifice of The Mass > Through the Mass the most perfect sacrifice is offered to God : Sacrifice is simply the offering of a gift to God. It is the offering of a gift to God by a priest and the destruction of the gift; the purpose of sacrifice is to show our total dependence on God. Sacrifice then, is essentially the giving of a gift to God. Christ offered the perfect gift to God on the cross: He offered Himself. Because Christ is God, this was the most perfect sacrifice that could be offered. Christ did the same thing at the Last Supper too. He offered Himself, a perfect gift, a perfect sacrifice, to Almighty God. The gift He offered was His own Body and Blood. Jesus Christ Himself was the priest. The destruction of the gift was the separate consecration of the bread and wine into His Body and Blood. This was the first Mass ever offered. It was offered by the Son of God Himself. He offered the same gift (Himself) that He offered on the cross. The sacrifice at the Last Supper was the same as that of the cross except that there were no blood and tears. This was an unbloody sacrifice.
