"It Is Finished": Do Purgatory and the Mass Deny Christ's Finished Work?

"It is finished." If Jesus paid it all, why do Catholics offer the Mass every day and pray for souls in purgatory? It is a serious objection, and it deserves a precise answer.

Short answer: No. The Catholic Church teaches that the work of redemption was finished on the cross, once for all, and can never be repeated or improved. The Mass does not repeat that sacrifice; it makes the one sacrifice of Calvary present. Purgatory does not add to Christ's payment; it is Christ's own blood finishing what it began in a soul. What was finished must still be applied, and Scripture shows Christ, our living High Priest, applying it.

What Protestants Believe

The Westminster Confession of Faith (1646) says of the Lord's Supper: "In this sacrament, Christ is not offered up to his Father; nor any real sacrifice made at all, for remission of sins of the quick or dead; but only a commemoration of that one offering up of himself, by himself, upon the cross, once for all." It concludes that "the popish sacrifice of the mass (as they call it) is most abominably injurious to Christ's one, only sacrifice, the alone propitiation for all the sins of his elect" (WCF 29.2). And: "Besides these two places, for souls separated from their bodies, the Scripture acknowledgeth none" (WCF 32.1).

The Heidelberg Catechism (1563), Q. 80: "The Lord's Supper declares to us that all our sins are completely forgiven through the one sacrifice of Jesus Christ, which he himself accomplished on the cross once for all." (crcna.org). Its original text calls the Mass "a denial of the one sacrifice and suffering of Jesus Christ," though the Christian Reformed Church now places that part in brackets, noting that it does not accurately reflect official Catholic teaching and practice today and is no longer confessionally binding on its members.

On purgatory, the evangelical site GotQuestions.org states the argument at its sharpest: "To say that we must also suffer for our sins is to say that Jesus' suffering was insufficient in some way," and "Jesus' once-for-all sacrifice was absolutely and perfectly sufficient (Hebrews 7:27)" (GotQuestions, "Purgatory"). It calls tetelestai "an accounting term that means 'paid in full'" (GotQuestions, "It is finished").

The case comes from real love for the cross: Hebrews says "once for all" again and again, so any further sacrifice or purification seems to insult the Savior.


What Catholics Actually Teach

The Catholic Church affirms the cross's sufficiency without reservation. Christ's death is "the Paschal sacrifice that accomplishes the definitive redemption of men" (CCC 613). "This sacrifice of Christ is unique; it completes and surpasses all other sacrifices" (CCC 614). "The redemptive sacrifice of Christ is unique, accomplished once for all" (CCC 1545).

The Mass. "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" (CCC 1366). Christ's "priesthood was not to end with his death" (CCC 1366, quoting Trent). And: "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.'" (CCC 1367).

Purgatory. "All who die in God's grace and friendship, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven" (CCC 1030). The Church calls it "this final purification of the elect, which is entirely different from the punishment of the damned" (CCC 1031). The "temporal punishment" of sin "must not be conceived of as a kind of vengeance inflicted by God from without," but as "following from the very nature of sin" (CCC 1472).

What Catholics do not teach:

  • That Christ is killed again or suffers again at Mass. He is offered "in an unbloody manner" (CCC 1367). Trent: the Mass is far "from derogating in any way from that (former oblation)" (Session 22, ch. 2).
  • That the priest is a second Savior. "Only Christ is the true priest" (CCC 1545).
  • That we pay part of the debt of eternal punishment. Forgiveness and restored communion with God "entail the remission of the eternal punishment of sin" (CCC 1473).

It all points to Christ. The Mass is Jesus Christ, the one High Priest, presenting His one sacrifice, so that "the sacrifice Christ offered once for all on the cross remains ever present" (CCC 1364). Purgatory is His blood completing its work in those who died in His friendship. Nothing is added to the cross; everything flows from it, and everything leads back to Him, the "one mediator between God and the human race, Christ Jesus" (1 Timothy 2:5).


The Biblical Case

1. "It is finished" and "being consecrated" stand side by side

Hebrews says both at once: "For by one offering he has made perfect forever those who are being consecrated" (Hebrews 10:14). One finished offering; people still "being consecrated." That is the heart of the Catholic position in one verse.

In St. John, Jesus was "aware that everything was now finished, in order that the scripture might be fulfilled" (John 19:28). Yet afterward He rose, ascended, and poured out the Spirit. None of that "added" to the cross. It applied it.

2. Christ's priesthood did not end at Calvary

Hebrews: "he, because he remains forever, has a priesthood that does not pass away. Therefore, he is always able to save those who approach God through him, since he lives forever to make intercession for them" (Hebrews 7:24–25). Finished as sacrifice, Christ's work continues as ministry.

Then: "Now every high priest is appointed to offer gifts and sacrifices; thus the necessity for this one also to have something to offer" (Hebrews 8:3). Enthroned in heaven, Christ is "a minister of the sanctuary and of the true tabernacle" (Hebrews 8:2). He offers no new victim, but Himself: He entered heaven itself "that he might now appear before God on our behalf" (Hebrews 9:24). St. John sees Him in heaven as "a Lamb that seemed to have been slain" (Revelation 5:6). The Mass is that same offering made present on earth.

3. Jesus commanded the Church to make His sacrifice present

At the Last Supper Jesus spoke in sacrificial terms: "This is my body, which will be given for you; do this in memory of me," and "This cup is the new covenant in my blood, which will be shed for you" (Luke 22:19–20). St. Paul: "For as often as you eat this bread and drink the cup, you proclaim the death of the Lord until he comes" (1 Corinthians 11:26). Not a new death: the one death, again and again. And Hebrews, the letter of "once for all," says: "We have an altar from which those who serve the tabernacle have no right to eat" (Hebrews 13:10). An altar is a place of sacrifice, and Christians eat from it.

4. Malachi foresaw one pure offering in every place

God rejected the corrupt priests' sacrifices: "I will not accept any offering from your hands!" (Malachi 1:10). Then: "Incense offerings are made to my name everywhere, and a pure offering; For my name is great among the nations, says the LORD of hosts" (Malachi 1:11). The NABRE note explains that this "pure offering" has been read as sacrifice in the Messianic Age, an interpretation the Council of Trent endorsed. A pure offering made "everywhere" among the nations, after the Temple's sacrifices are rejected, fits one thing: Christ's one sacrifice made present in the Eucharist. The first Christians read it exactly that way (below).

5. The apostles apply the finished work, and so do we

St. Paul writes: "Now I rejoice in my sufferings for your sake, and in my flesh I am filling up what is lacking in the afflictions of Christ on behalf of his body, which is the church" (Colossians 1:24). The NABRE note: this "does not imply that Christ's atoning death on the cross was defective." Yet St. Paul's sufferings, united to Christ, serve the Church. He tells believers, "work out your salvation with fear and trembling. For God is the one who, for his good purpose, works in you both to desire and to work" (Philippians 2:12–13). God even entrusts men with "the ministry of reconciliation" (2 Corinthians 5:18).

6. Saved, "but only as through fire"

On the foundation, "namely, Jesus Christ," each builds, and "the fire [itself] will test the quality of each one's work." "But if someone's work is burned up, that one will suffer loss; the person will be saved, but only as through fire" (1 Corinthians 3:11–15). A man saved, on Christ's foundation, still suffers loss and passes through fire. Not hell, not yet heaven's joy: purification, because "nothing unclean will enter" the heavenly city (Revelation 21:27).

7. Protestants already admit "finished" is not "applied"

Historic Protestantism does not teach that everyone is saved simply because the cross is finished. Westminster calls faith "the alone instrument of justification" (WCF 11.2): the finished work must still be received, and "how can they believe in him of whom they have not heard?" (Romans 10:14). Sanctification is "yet imperfect in this life" (WCF 13.2). Preaching, believing, and growing in holiness do not insult the cross; neither do the Mass and purgatory. The only question is how Christ applies His work: through faith, Baptism, the Eucharist, and, for those not yet purified at death, a final cleansing.


Objections Answered

(a) "Hebrews 10:18 says there is no longer any offering for sin."

At its strongest: "Where there is forgiveness of these, there is no longer offering for sin" (Hebrews 10:18). Christ "offered one sacrifice for sins, and took his seat forever" (Hebrews 10:12), unlike the priest who "stands daily at his ministry" (10:11). A priest at an altar every day looks like what Hebrews says has ended.

Answer: Hebrews 10:18 rules out another offering for sin alongside or after Christ's. The Mass is not another offering. "The victim is one and the same" (CCC 1367). And Hebrews itself says Christ must "have something to offer" in heaven (Hebrews 8:3), and that Christians have "an altar" (Hebrews 13:10). If 10:18 banned every continuing presentation of the one sacrifice, it would ban Christ's own heavenly ministry (7:25; 8:3).

(b) "The Mass re-sacrifices Christ, but Hebrews 9 says He will not suffer repeatedly."

At its strongest: Christ did not enter heaven "that he might offer himself repeatedly"; "if that were so, he would have had to suffer repeatedly from the foundation of the world. But now once for all he has appeared at the end of the ages to take away sin by his sacrifice" (Hebrews 9:25–26). He has "no need... to offer sacrifice day after day" (Hebrews 7:27). Yet Mass is daily.

Answer: Hebrews ties "repeatedly" to suffering. The Catholic Church teaches that Christ does not suffer or die at Mass. He is offered "in an unbloody manner" (CCC 1367), for "Christ, raised from the dead, dies no more; death no longer has power over him" (Romans 6:9). What is repeated is not the sacrifice but the Church's participation in it, as Israel kept the Passover yearly without a new Exodus. As often as we eat and drink, "you proclaim the death of the Lord" (1 Corinthians 11:26). See Is the Mass a Re-Sacrifice of Jesus?

(c) "Purgatory adds punishment Christ already bore."

At its strongest: "To say that we must also suffer for our sins is to say that Jesus' suffering was insufficient in some way" (GotQuestions). If the debt is paid in full, further suffering denies His payment.

Answer: Scripture separates forgiveness from sin's every consequence. When David repented, Nathan answered, "the LORD has removed your sin. You shall not die," yet added, "the child born to you will surely die" (2 Samuel 12:13–14). Purgatory is not a second payment of eternal debt; that is remitted by Christ alone (CCC 1473). It is the healing of a soul still attached to sin, the temporal punishment that follows "from the very nature of sin," not "vengeance inflicted by God from without" (CCC 1472). Purgatory is sanctification completed. What purifies is not our power, but "the blood of Christ," which will "cleanse our consciences from dead works to worship the living God" (Hebrews 9:14). See Where Is Purgatory in the Bible?

(d) "Catholics add their works to Christ's work."

At its strongest: Prayers and Masses for the dead look like human effort stacked on grace. If we contribute anything, Christ did not do it all.

Answer: Christ did it all, including making us His Body, so that we act with Him. "In the Eucharist the sacrifice of Christ becomes also the sacrifice of the members of his Body" (CCC 1368). Praying for the dead asks Christ to apply His blood; the Mass for the departed is offered for those "who 'have died in Christ but are not yet wholly purified'" (CCC 1371). The practice is older than the Church: Judas Maccabeus "made atonement for the dead that they might be absolved from their sin," and Scripture calls it "a holy and pious thought" (2 Maccabees 12:44–46). Even read only as history, it shows Jews praying for the dead before Christ. Christ "became the source of eternal salvation for all who obey him" (Hebrews 5:9): obedience does not compete with Him. He is its source.


The Early Church Agrees

  • The Didache (late 1st or early 2nd century), ch. 14: "But every Lord's day gather yourselves together, and break bread, and give thanksgiving after having confessed your transgressions, that your sacrifice may be pure... For this is that which was spoken by the Lord: In every place and time offer to me a pure sacrifice" (newadvent.org). The Eucharist is "your sacrifice," and Malachi 1:11 its prophecy.
  • St. Justin Martyr (Dialogue with Trypho 41, c. AD 155–160): the offering of fine flour "was a type of the bread of the Eucharist, the celebration of which our Lord Jesus Christ prescribed, in remembrance of the suffering which He endured." Of Malachi, he says God speaks of the Gentiles "who in every place offer sacrifices to Him, i.e., the bread of the Eucharist, and also the cup of the Eucharist" (newadvent.org). Remembrance and sacrifice together.
  • St. Irenaeus of Lyons (Against Heresies 4.17.5, c. AD 180): Christ "took that created thing, bread, and gave thanks, and said, 'This is My body,'" and so "taught the new oblation of the new covenant; which the Church receiving from the apostles, offers to God throughout all the world." He then quotes Malachi: "in every place incense is offered to My name, and a pure sacrifice" (newadvent.org).
  • The inscription of Abercius (Phrygia, late 2nd or early 3rd century; older than a related inscription dated AD 216): St. Abercius, Bishop of Hieropolis, wrote of the faith that "ever gives to its friends to eat, it having wine of great virtue, and giving it mingled with bread," and asked: "Let the brother who shall understand this [pray] for Abercius" (Catholic Encyclopedia, "Abercius"). In his own epitaph, a bishop asks the faithful to pray for him.
  • Tertullian (De Corona 3, c. AD 211): "As often as the anniversary comes round, we make offerings for the dead as birthday honours" (newadvent.org).
  • St. Cyprian of Carthage (Epistle 62 to Caecilius, numbered 63 in some editions, c. AD 253): "that priest truly discharges the office of Christ, who imitates that which Christ did; and he then offers a true and full sacrifice in the Church to God the Father" (ch. 14). And: "we make mention of His passion in all sacrifices (for the Lord's passion is the sacrifice which we offer)" (ch. 17; newadvent.org).

None of them thought this threatened the cross. It was the cross reaching them.


Conclusion

"It is finished" is a Catholic verse. The Mass is that finished sacrifice made present, so that "the work of our redemption is carried out" (CCC 1364). Purgatory is that same sacrifice completing its work in a soul Christ has already saved. Finished does not mean idle: Christ "lives forever to make intercession" (Hebrews 7:25).

If you are Protestant, you already believe the finished work must be preached, believed, and lived. Follow that to the end, and you will find the Mass and purgatory kneeling before the cross, not competing with it.

Come home. The one sacrifice of Calvary that you love is offered, made present, and applied every day at the altars of the Catholic Church. Christ did not found many churches. He founded one, on St. Peter and the apostles (Matthew 16:18), and that Church is the Catholic Church. "It is through Christ's Catholic Church alone, which is the universal help toward salvation, that the fullness of the means of salvation can be obtained" (CCC 816). If you are a baptized Christian, you already share "a certain, although imperfect, communion" with her (CCC 838). Every truth you already hold is a call to the rest of the way. Christ is calling you into the Catholic Church.

Your next step: Come to Mass this Sunday at your local Catholic church. You can find one near you at MassTimes.org. Everyone is welcome; if you're not yet Catholic, pray with us but don't receive Communion yet.

FAQ

Does the Catholic Church teach that Christ dies again at every Mass? No. "The sacrifice of Christ and the sacrifice of the Eucharist are one single sacrifice"; Christ is offered "in an unbloody manner" (CCC 1367). The Mass makes the one sacrifice present; it does not repeat it.

If Jesus paid it all, why do Catholics pray for the dead? Because those who die "in God's grace and friendship, but still imperfectly purified" still need the purification Christ's blood brings (CCC 1030), and the Church has prayed for them "from the beginning" (CCC 1032). See Did the Early Church Believe in Purgatory?

Can anyone in purgatory end up in hell? No. Everyone in purgatory is "assured of their eternal salvation" (CCC 1030). Purgatory is "this final purification of the elect, which is entirely different from the punishment of the damned" (CCC 1031).
