Is the Mass a Re-Sacrifice of Christ? — What Calvin Argued, and What the Sources Say

Calvin called the Mass "a sacrifice and oblation for obtaining the remission of sins" — and declared that belief "the head of this horrid abomination" Calvin Institutes IV.18.1. The charge is precise: if Christ was offered "once for all" in Hebrews' Greek, then any liturgical re-offering either contradicts Hebrews or is redundant. This article works through the primary sources in order — the Greek of Hebrews, the dominical command at the Last Supper, patristic witnesses from the first four centuries, and Trent's formal response — to show exactly where the Catholic and Reformed positions diverge, and on what the sources actually settle.

§1. What Hebrews Says About the Once-for-All Sacrifice

The Epistle to the Hebrews declares that Christ was offered "once for all" (ἅπαξ), in a single historical immolation that is not repeated Heb 7:27 Heb 9:12 Heb 9:28 Heb 10:10-14. The text states that Christ "needeth not daily (as the other priests) to offer sacrifices, first for his own sins, and then for the people's: for this he did once, in offering himself" Heb 7:27. The Greek text of this passage employs the term ἐφάπαξ, emphasizing the singularity of the oblation: "τοῦτο γὰρ ἐποίησεν ἐφάπαξ ἑαυτὸν ἀνενέγκας" Heb 7:27.

The letter continues: "Neither by the blood of goats or of calves, but by his own blood, entered once into the Holies, having obtained eternal redemption" Heb 9:12. The Greek reads "εἰσῆλθεν ἐφάπαξ εἰς τὰ ἅγια" Heb 9:12. This same chapter concludes with the assertion that "Christ was offered once to exhaust the sins of many" Heb 9:28, where the Greek text states "οὕτως καὶ ὁ Χριστός ἅπαξ προσενεχθεὶς" Heb 9:28.

The tenth chapter reinforces this unrepeatable character: "In the which will, we are sanctified by the oblation of the body of Jesus Christ once" Heb 10:10-14, and "by one oblation he hath perfected for ever them that are sanctified" Heb 10:10-14. The Greek of verse 10 employs ἐφάπαξ again: "διὰ τῆς προσφορᾶς τοῦ σώματος Ἰησοῦ Χριστοῦ ἐφάπαξ" Heb 10:10. This repeated emphasis on the singularity of Christ's self-offering — ἅπαξ and ἐφάπαξ — constitutes the scriptural foundation upon which Calvin built his objection to the Mass as sacrifice.

§2. What Christ Said at the Last Supper

Christ's command at the Last Supper is recorded as "Do this in remembrance of me" — εἰς τὴν ἐμὴν ἀνάμνησιν Lk 22:19 1Cor 11:24-25. The Douay-Rheims translation renders Luke 22:19: "This is my body, which is given for you. Do this for a commemoration of me" Lk 22:19. The parallel account in First Corinthians states: "This do for the commemoration of me... This do ye, as often as you shall drink, for the commemoration of me" 1Cor 11:24-25.

The Greek text of Luke preserves the exact phrase: "τοῦτό ἐστιν τὸ σῶμά μου τὸ ὑπὲρ ὑμῶν διδόμενον τοῦτο ποιεῖτε εἰς τὴν ἐμὴν ἀνάμνησιν" Lk 22:19. Similarly, Paul records the dominical command as "Τοῦτό μού ἐστιν τὸ σῶμα τὸ ὑπὲρ ὑμῶν τοῦτο ποιεῖτε εἰς τὴν ἐμὴν ἀνάμνησιν" 1Cor 11:24. The substantive ἀνάμνησις (anamnēsis), appearing in the accusative singular ἀνάμνησιν, translates the Hebrew zikkaron or azkarah — terms with cultic, sacrificial resonance in the Septuagint.

§3. The Greek and the Vulgate

The word ἅπαξ in Hebrews refers to the unrepeatable historical sufficiency of Christ's self-offering Heb 9:28. The Greek text of Hebrews 9:28 employs ἅπαξ to modify the participle προσενεχθείς: "οὕτως καὶ ὁ Χριστός ἅπαξ προσενεχθεὶς" Heb 9:28. The Vulgate renders this with the Latin adverb semel: "sic et Christus, semel oblatus ad multorum auferenda peccata" Heb 9:28.

The Vulgate renders Luke 22:19 with the phrase in meam commemorationem: "Hoc facite in meam commemorationem" Lk 22:19. This Latin diction — commemoratio — carries forward into the Roman Canon's memores… offerimus, preserving the sacrificial-memorial sense from the fourth century forward.

The Greek ἀνάμνησις in LXX cultic contexts (Lev 24:7; Num 10:10) denotes the memorial portion of a sacrifice, not merely mental recollection.

§4. What Calvin Actually Argued

Calvin's argument in Institutes IV.18 operates on two levels: that the Mass claims to be a propitiatory sacrifice, and that this claim directly contradicts the sufficiency of Calvary. He opens Chapter 18 by identifying the Mass with what he calls "the head of this horrid abomination" — the belief "that the Mass was a sacrifice and oblation for obtaining the remission of sins" Calvin Institutes IV.18.1.

In §3 of that chapter, Calvin presses the Hebrews argument directly: "if, on the cross, he offered himself in sacrifice that he might sanctify us for ever, and purchase eternal redemption for us, undoubtedly the power and efficacy of his sacrifice continues without end" Calvin Institutes IV.18.3. He concludes from this that any Mass-sacrifice either concedes that the cross was insufficient or invents a new oblation — and either option, in his reading, overturns the finality of Christ's death Calvin Institutes IV.18.3.

Calvin extends this in §5, arguing that each Mass in effect promises "a new forgiveness of sins, a new purchase of righteousness, so that now there are as many testaments as there are masses" Calvin Institutes IV.18.5. His §8 turns to the specific practice of private masses as a violation of the communal institution Calvin Institutes IV.18.8.

The Thirty-Nine Articles of the Church of England codified this criticism: Article 31 declares that "the sacrifices of Masses, in the which it was commonly said, that the Priest did offer Christ for the quick and the dead, to have remission of pain or guilt, were blasphemous fables, and dangerous deceits" 39Art 31.

§5. What the Fathers Taught

The patristic witness predates the Reformation controversy and is therefore not shaped by it. Three witnesses from the first five centuries are directly relevant.

Ignatius of Antioch (d. c. 107) identifies the Eucharist as "the flesh of our Saviour Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again" Ignatius:Smyrnaeans 7.1. Ignatius treats those who "abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Saviour" as having incurred death "in the midst of their disputes" Ignatius:Smyrnaeans 7.1. The sacrificial language is implicit in the identification of the Eucharist with the flesh that "suffered."

Cyril of Jerusalem (d. 386), in his Mystagogical Catecheses, explicitly calls the Eucharistic celebration "the spiritual sacrifice, the bloodless service" and "that sacrifice of propitiation" CyrilJerusalem:Catechetical 23.8-10. He describes the assembled faithful as those who "offer to Him our supplications for those who have fallen asleep" and states that they "offer up Christ sacrificed for our sins, propitiating our merciful God for them as well as for ourselves" CyrilJerusalem:Catechetical 23.8-10. This is a fourth-century bishop using propitiatory sacrificial language for the Eucharistic celebration — the same language Calvin's canon condemns.

John Chrysostom (d. 407) addresses the Hebrews text directly in his Homilies on Hebrews. He poses his own objection: "What then? do not we offer every day?" and answers: "We offer indeed, but making a remembrance of His death, and this remembrance is one and not many. How is it one, and not many? Inasmuch as that Sacrifice was once for all offered, and carried into the Holy of Holies. This is a figure of that sacrifice and this remembrance of that. For we always offer the same, not one sheep now and to-morrow another, but always the same thing: so that the sacrifice is one" Chrysostom:Hom-heb 17.6. Chrysostom's formulation — same sacrifice, one and not many, a figure and remembrance — anticipates the precise distinction Trent would later define.

§6. What Trent Defined

The Council of Trent addressed Calvin's objection in Session 22 (1562). The council's Chapter I acknowledges the Hebrews text directly: Christ "was about to offer Himself once on the altar of the cross unto God the Father, by means of his death, there to operate an eternal redemption; nevertheless, because that His priesthood was not to be extinguished by His death," he established at the Last Supper "a visible sacrifice, such as the nature of man requires, whereby that bloody sacrifice, once to be accomplished on the cross, might be represented, and the memory thereof remain" Trent Sess22 Ch1.

Chapter II states the identity of victim: "that same Christ is contained and immolated in an unbloody manner, who once offered Himself in a bloody manner on the altar of the cross" and "the victim is one and the same, the same now offering by the ministry of priests, who then offered Himself on the cross, the manner alone of offering being different" Trent Sess22 Ch2. Trent thus concedes the Hebrews data: one victim, one sacrifice — but insists the Mass is not a second sacrifice; it is the same sacrifice made present under a different mode.

Canon 1 anathematizes those who say "that in the mass a true and proper sacrifice is not offered to God" Trent Sess22 Can1. Canon 3 anathematizes those who say "the sacrifice of the mass is only a sacrifice of praise and of thanksgiving; or, that it is a bare commemoration of the sacrifice consummated on the cross, but not a propitiatory sacrifice" Trent Sess22 Can3.

§7. Aquinas and the Scholastic Synthesis

Thomas Aquinas had already worked through the same distinction in the Summa Theologiae. He cites Augustine: "Christ was sacrificed once in Himself, and yet He is sacrificed daily in the Sacrament" III q.83 a.1. Aquinas's explanation is that "the celebration of this sacrament is an image representing Christ's Passion, which is His true sacrifice" and that it is also called a sacrifice "in respect of the effect of His Passion: because, to wit, by this sacrament, we are made partakers of the fruit of our Lord's Passion" III q.83 a.1. The Scholastic framework Aquinas provides — sacramental re-presentation of the one sacrifice, application of its fruits — is the framework Trent formalized.

§8. The Catholic Position Stated Formally

The Catechism of the Catholic Church brings together the Tridentine definition and the patristic witness. §1366 states that 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." The quoted Tridentine text follows: Christ "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... [he wanted] to leave to his beloved spouse the Church a visible sacrifice... by which the bloody sacrifice which he was to accomplish once for all on the cross would be re-presented" §1366.

§1367 restates the identity of victim: "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.'"

§1382 summarizes the dual character: "The Mass is at the same time, and inseparably, the sacrificial memorial in which the sacrifice of the cross is perpetuated and the sacred banquet of communion with the Lord's body and blood."

The Old Testament prophecy of Malachi is also cited in this connection: "For from the rising of the sun even to the going down, my name is great among the Gentiles, and in every place there is sacrifice, and there is offered to my name a clean oblation" Mal 1:11. The Douay-Rheims note glosses "a clean oblation" as "viz., the precious body and blood of Christ in the eucharistic sacrifice" Mal 1:11.

§9. Where the Sources Settle the Question — and Where They Do Not

The sources settle several things. First, the Greek of Hebrews is unambiguous: ἐφάπαξ and ἅπαξ denote a single, unrepeatable, historically sufficient sacrifice. Calvin, Trent, Chrysostom, and the Catechism all read Hebrews that way. There is no dispute on the exegetical datum.

Second, the dispute is entirely about what the Mass is in relation to that datum. Calvin reads the Mass as a claim to perform a new and additional sacrifice — and on that reading, Hebrews refutes it. Trent reads the Mass as a sacramental making-present of the one sacrifice, distinguished from it only by mode (unbloody rather than bloody), not by number. On Trent's reading, Hebrews does not refute the Mass because the Mass does not add a second sacrifice.

Third, Chrysostom's Homilies on Hebrews show that the distinction between "one sacrifice" and "daily offering" was operative in the Greek patristic tradition before either the medieval Scholastics or the Reformation. Chrysostom's answer to his own objection — "we offer the same, not one sheep now and tomorrow another, but always the same thing: so that the sacrifice is one" — is structurally identical to Trent's answer to Calvin Chrysostom:Hom-heb 17.6.

What the sources do not settle is whether Trent's ontological account of re-presentation — sacramental identity of the offered victim across historical time — is exegetically required by Hebrews or is a theological interpretation added to it. That is a live question between Catholic and Reformed exegetes. Readers who wish to pursue it further are directed to the primary texts of Session 22 and to Calvin's Institutes IV.18 in full, both of which are cited below.
