The Mass as Sacrifice

The big question

The Letter to the Hebrews says Christ offered himself “once for all” (Hebrews 10:10). So how can Catholics call the Mass a sacrifice? Does the priest crucify Christ again at every Mass? Wasn’t the Cross enough?

What the Church teaches

The Mass is a true and proper sacrifice (Trent, Session XXII, canon 1; DH 1751; CCC 1365–1367).

It is the same sacrifice as the Cross, made present, not repeated. The victim is the same, Christ; the one offering is the same, Christ, now through the ministry of the priest; only the manner of offering is different, bloody on the Cross and unbloody in the Mass (Trent, Session XXII, ch. 2; DH 1743; CCC 1367).

It is offered for the sins of the living and the dead (Trent, Session XXII, canon 3; DH 1753; CCC 1371).

How sure is this? De fide. See CCC 1362–1372.

Where it comes from

Scripture. The prophet Malachi foretold a new, universal offering: “from the rising of the sun to its setting my name is great among the nations, and in every place incense is offered to my name, and a pure offering” (Malachi 1:11). At the Last Supper Jesus used the language of sacrifice: “This is my body which is given for you… This chalice which is poured out for you is the new covenant in my blood” (Luke 22:19–20). He commanded, “Do this in remembrance of me.” St Paul contrasts “the table of the Lord” with pagan altars of sacrifice (1 Corinthians 10:21), and Hebrews says, “We have an altar” (Hebrews 13:10).

Hebrews also teaches that Christ’s sacrifice is unique: “we have been sanctified through the offering of the body of Jesus Christ once for all” (Hebrews 10:10).

The early Church. The Didache, a church manual from the late first century, calls the Sunday Eucharist a “sacrifice” and applies Malachi’s prophecy to it (Didache 14). St Augustine explained that the Church, being Christ’s body, learns to offer herself through him in the daily sacrifice (City of God 10.20).

How theologians explain it

One sacrifice, made present. The key is that the Mass does not add another sacrifice to the Cross. It makes the one sacrifice of the Cross present, here and now, so that we can take part in it. The Catechism says the Eucharist “re-presents” (makes present again) the sacrifice of the Cross (CCC 1366).

	The Cross	The Mass
The victim	Christ	The same Christ
The one who offers	Christ	The same Christ, through the priest
The manner	Bloody: Christ really died	Unbloody: under the signs of bread and wine
When	Once, on Good Friday	At every Mass, until he comes again
What it achieves	Won our redemption	Applies that redemption to us

What “memorial” means. “Do this in remembrance of me” does not mean simply “think about me”. In the Bible, a memorial (anamnesis) is a celebration that makes a past saving event present to those who keep it. At Passover, Jews do not just recall the Exodus; each generation takes part in it. The Eucharist is the memorial of Christ’s Passover in this full sense (CCC 1363–1364).

The separate consecration. Many theologians see the sacrifice expressed in the separate consecration of bread and wine. Christ’s body and blood are made present under separate signs, which represents his death, when his blood was separated from his body, even though the whole living Christ is present under each.

The whole Church offers. The priest acts in the person of Christ. But the whole Church, priest and people together, offers Christ to the Father and offers itself with him: its prayers, work, joys and sufferings (CCC 1368). This is the meaning of the people’s “active participation” that Vatican II encouraged (Sacrosanctum Concilium 48).

Both sacrifice and meal. The Mass is at once the sacrifice in which the Cross is made present, the memorial of Christ’s Passover, and the sacred banquet of communion (CCC 1382). These are not rival descriptions; they are three aspects of one reality.

Philosophy bridge

The philosophy course’s treatment of signs explains how a sign can make something present without being that thing in its ordinary form. A sacramental sign goes further: it makes present what it signifies. In the Mass, the signs of bread and wine, consecrated separately, make the one sacrifice of the Cross present.

What the Church does not claim

• Not that Christ is re-crucified or dies again. He “dies no more” (Romans 6:9). The Mass is unbloody.
• Not that the Mass adds anything to the Cross. It makes the one sacrifice present and applies its fruits.
• Not that the priest is a separate mediator. He acts in the person of Christ, the one mediator.
• Not that the Mass is only a meal, or only a sacrifice. It is both, and a memorial.

Check your understanding

1. According to Trent, what is the same and what is different between the Cross and the Mass?

Show answer

The same: the victim (Christ) and the one who offers (Christ, through the priest). Different: the manner of offering, bloody on the Cross and unbloody in the Mass.

2. If Christ’s sacrifice was “once for all” (Hebrews 10:10), how can the Mass be a sacrifice?

Show answer

Because the Mass is not a new or additional sacrifice. It makes the one sacrifice of the Cross present, so that we can share in it.

3. Explain what “memorial” means in the biblical sense, using Passover.

Show answer

A biblical memorial makes a past saving event present to those who celebrate it. At Passover each generation takes part in the Exodus. In the Eucharist, Christ’s Passover from death to life is made present.

4. What early evidence is there that Christians saw the Eucharist as a sacrifice?

Show answer

The Didache (late first century) calls the Eucharist a sacrifice and applies Malachi 1:11 to it. Augustine later described the Church offering herself through Christ in the daily sacrifice.

5. What does it mean that the whole Church offers the Mass?

Show answer

The priest acts in the person of Christ, but all the faithful offer Christ to the Father and offer themselves with him, uniting their lives to his sacrifice.
