Catholic Position

¶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.”

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. “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.”

Scripture Says

Hebrews 9:26-27
26  For then must he often have suffered since the foundation of
the world: but now once in the end of the world hath he appeared to put
away sin by the sacrifice of himself.
27  And as it is appointed unto men once to die, but after this the judgment:

Hebrews 10:10-12
10  By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
11  And every priest standeth daily ministering and offering
oftentimes the same sacrifices, which can never take away sins:
12  But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;

Hebrews 9:12
12  Neither by the blood of goats and calves, but by his own blood
he entered in once into the holy place, having obtained eternal
redemption for us.

1 Peter 3:18
18 ¶  For Christ also hath once suffered for sins, the just for
the unjust, that he might bring us to God, being put to death in the
flesh, but quickened by the Spirit:
