Hello,
Yes I am not denying that, but again there is no need for it to be repeated again and again. It happened once and for all, not once and for all and then a thousand times a day the world over.
We don’t repeat it - we enter into it and make it present.
Here is from the
Catechism on the sacramental nature of the Eucharist:
The sacrificial memorial of Christ and of his Body, the Church
1362
The Eucharist is the memorial of Christ’s Passover, the making present and the sacramental offering of his unique sacrifice, in the liturgy of the Church which is his Body. In all the Eucharistic Prayers we find after the words of institution a prayer called the anamnesis or memorial.
1363
In the sense of Sacred Scripture the memorial is not merely the recollection of past events but the proclamation of the mighty works wrought by God for men.(Cf. ⇒ Ex 13:3.) In the liturgical celebration of these events, they become in a certain way present and real. This is how Israel understands its liberation from Egypt: every time Passover is celebrated, the Exodus events are made present to the memory of believers so that they may conform their lives to them.
1364 In the New Testament, the memorial takes on new meaning.
When the Church celebrates the Eucharist, she commemorates Christ’s Passover, and it is made present the sacrifice Christ offered once for all on the cross remains ever present.(Cf. ⇒ Heb 7:25-27.) “As often as the sacrifice of the Cross by which ‘Christ our Pasch has been sacrificed’ is celebrated on the altar, the work of our redemption is carried out.”(LG 3; cf. ⇒ 1 Cor 5:7.)
1365
Because it is the memorial of Christ’s Passover, the Eucharist is also a sacrifice. the sacrificial character of the Eucharist is manifested in the very words of institution: “This is my body which is given for you” and “This cup which is poured out for you is the New Covenant in my blood.”(⇒ Lk 22:19-20.) In the Eucharist Christ gives us the very body which he gave up for us on the cross, the very blood which he “poured out for many for the forgiveness of sins.”(⇒ Mt 26:28.)
1366
The Eucharist is thus a sacrifice because it re-presents (makes present) the sacrifice of the cross, because it is its memorial and because it applies its fruit:
[Christ], our Lord and God, was once and for all to offer himself to God the Father by his death on the altar of the cross, to accomplish there an everlasting redemption.
But because his priesthood was not to end with his death, at the Last Supper “on the night when he was betrayed,” [he wanted] to leave to his beloved spouse the Church a visible sacrifice (as the nature of man demands) by which the bloody sacrifice which he was to accomplish once for all on the cross would be re-presented, its memory perpetuated until the end of the world, and its salutary power be applied to the forgiveness of the sins we daily commit.(Council of Trent (1562): DS 1740; cf. ⇒ 1 Cor 11:23; ⇒ Heb 7:24, ⇒ 27.)
1367
The sacrifice of Christ and the sacrifice of the Eucharist are one single sacrifice: “The victim is one and the same: the same now offers through the ministry of priests, who then offered himself on the cross; only the manner of offering is different.” “In this divine sacrifice which is celebrated in the Mass, the same Christ who offered himself once in a bloody manner on the altar of the cross is contained and is offered in an unbloody manner.”(Council of Trent (1562): DS 1743; cf. ⇒ Heb 9:14, ⇒ 27.)
1368 The Eucharist is also the sacrifice of the Church. the Church which is the Body of Christ participates in the offering of her Head. With him, she herself is offered whole and entire. She unites herself to his intercession with the Father for all men. In the Eucharist the sacrifice of Christ becomes also the sacrifice of the members of his Body. the lives of the faithful, their praise, sufferings, prayer, and work, are united with those of Christ and with his total offering, and so acquire a new value. Christ’s sacrifice present on the altar makes it possible for all generations of Christians to be united with his offering.
In the catacombs the Church is often represented as a woman in prayer, arms outstretched in the praying position. Like Christ who stretched out his arms on the cross, through him, with him, and in him, she offers herself and intercedes for all men.
