The Atonement: How Does Christ’s Death Save?
For the Son of Man also came not to be served, but to serve, and to give his life as a ransom for many.Mark 10:45 · World English Bible
Original Language & Text
The Greek word for “ransom” in Mark 10:45 is a word used for the price paid to free a slave or captive — the verse never says who the ransom is paid to, which is exactly the detail later theologians argued about. The Greek word in Romans 3:25, translated “propitiation” in some Bibles and “expiation” in others, is the same word used elsewhere for the “mercy seat,” the cover of the ark of the covenant where blood was sprinkled once a year on the Day of Atonement. A scholar named C. H. Dodd argued in 1935 that the word really just means “removing or cleansing sin,” while Leon Morris argued that Romans talks so much about God’s anger at sin that the word has to include the idea of turning that anger aside. Both are serious, respected positions — it’s a genuine, unresolved disagreement, not a case of one side being wrong. A third Greek word, used in 2 Corinthians, gives us the “reconciliation” picture — two parties, God and humanity, being brought back into relationship, more like a broken friendship being restored than a legal case being settled.
Key Terms in the Original Language
“ransom” (Mark 10:45)
A commercial/liberation term for the price paid to free a slave or captive; the text never specifies to whom the ransom is paid, a gap later theologians (Origen, Anselm) resolved very differently.
“propitiation” / “mercy seat” (Rom. 3:25)
The same word renders the Hebrew kapporet, the ark's mercy seat (Heb. 9:5); translated “propitiation” (appeasing wrath) or “expiation” (removing sin) depending on the translation, an unresolved scholarly debate rather than a translation error.
“reconciliation” (2 Cor. 5:18-19)
A relational rather than legal or commercial image, picturing two estranged parties (God and humanity) restored to relationship.
“mercy seat” (Exod. 25:17)
The gold cover of the ark of the covenant where the high priest sprinkled blood on the Day of Atonement; the Septuagint's use of hilasterion to translate this term is the direct link between Romans 3:25 and the Old Testament sacrificial system.
History & Authorship
The New Testament describes what Jesus's death accomplishes using several different pictures without ever picking just one, and the early church did the same thing. The earliest Christian writers mostly talked about Jesus's death as a ransom that freed humanity from slavery to sin, death, and the devil, and as a victory over those hostile powers. Some early writers even wondered, somewhat oddly to modern ears, whether the ransom was paid to the devil himself. A theologian named Anselm, writing in 1098, thought that idea made God look weak, so he came up with a different picture: sin offends God's honor, and Jesus's death pays the debt that honor requires. Not long after, another theologian named Peter Abelard pushed back, arguing instead that Jesus's death is really about showing us how much God loves us, moving us to love God back, rather than paying off any kind of debt. Later, during the Protestant Reformation, teachers like John Calvin took Anselm's idea and made it more specifically legal: Jesus takes the punishment sinners deserve, satisfying God's justice. In 1617, a thinker named Hugo Grotius proposed a middle position: God needs to publicly uphold how serious sin is, and Jesus's suffering does that, without it being an exact one-for-one punishment swap. Finally, in 1930, a scholar named Gustaf Aulén wrote an influential book arguing that the earliest “ransom and victory” picture was actually its own solid, coherent view all along, not just a primitive idea people grew out of — and that argument renewed a lot of interest in that older picture.
How This Debate Developed
-
2nd–4th century CE
Ransom / Christus Victor motif dominant
Patristic preaching favors ransom and victory language; Irenaeus's recapitulation and speculation (linked to Origen) that Christ's death ransomed humanity from the devil's hold.
-
1098
Anselm's Cur Deus Homo
Rejects ransom paid to the devil as beneath God's dignity; reframes the atonement as satisfaction for the offense sin gives to God's honor.
-
early 1100s
Abelard's moral-influence critique
Argues against Anselm that Christ's death is primarily a demonstration of divine love meant to evoke a loving response, not a legal transaction.
-
16th century
Penal substitution formalized
Calvin and other Reformers recast Anselm's satisfaction framework in explicitly penal/legal terms; codified in the Heidelberg Catechism (1563) and later the Westminster Confession (1646).
-
1617
Grotius's governmental theory
De Satisfactione Christi, written against the Socinians, proposes God as moral governor upholding the law through Christ's suffering without a strict one-to-one penalty transfer.
-
1930–1931
Aulén's Christus Victor
Revives and systematizes the patristic ransom/victory motif as a coherent view in its own right, renewing 20th-century interest in it.
The Popular / Mainstream View
Since the Protestant Reformation, most Western Protestant and evangelical churches have taught that Jesus took the punishment that sinners deserved, satisfying God's justice so that people who trust in Jesus are treated as legally forgiven. This is the version most commonly preached and taught today, especially in Reformed, Baptist, and other evangelical churches, usually pointing to Isaiah 53, Romans 3:25, and 2 Corinthians 5:21. Even people who hold this view often caution against treating it as the only correct explanation, since the Bible itself uses several different pictures for what the cross accomplishes, not just this one legal picture.
Minority & Alternative Views
Christus Victor / Ransom
The oldest explanation, brought back into wider attention by a scholar named Gustaf Aulén: Jesus's death and resurrection defeat the powers — sin, death, and the devil — that hold humanity captive. This is still the main view in Eastern Orthodox Christianity, and more Western Christians have become interested in it again as a way to balance out an overly legal-sounding explanation of the cross. Critics say it doesn't fully explain the personal guilt side of things that shows up so much in Paul's letters.
Moral influence (Abelard)
Jesus's death is mainly meant to show us how much God loves us, so that we're moved to love God back, rather than to pay off some kind of legal or cosmic debt. This idea is linked to Peter Abelard and became more popular later on in some more liberal branches of Protestant theology. Critics ask why Jesus's suffering specifically would be necessary if the point is just to show love — and worry this view can make the cross feel like just an inspiring example rather than something that actually changes a person's standing with God.
Governmental theory (Grotius)
Connected to Hugo Grotius and historically popular among Methodists and other Wesleyan-influenced churches: God can't just forgive sin without some public act showing how seriously he takes his own laws. Jesus's suffering is that public demonstration, without it being an exact, one-for-one punishment swap for each individual sinner. This difference matters for whether Jesus's death applies to absolutely everyone or only to a specific group chosen ahead of time.
What Scholars Say
Many scholars today think it's a mistake to pick just one of these explanations as “the correct one.” Instead, they see the ransom, satisfaction, punishment, love, and government pictures as different images the New Testament itself uses side by side, without ever settling on one official explanation. A separate but related question is whether the “suffering servant” passage in Isaiah 52-53 was originally understood as being about a future Messiah, or whether it was first about the nation of Israel or some historical figure, and only later read as being about Jesus (see the Messianic Prophecy topic for more on that). Worth saying plainly: when different Bible translations use “propitiation” in one place and “expiation” in another for the exact same Greek word, that's not a mistake by either translation team — it reflects a real, still-unresolved disagreement among scholars about exactly what that word means in context.
What the Confessions Say
Lutheran — Augsburg Confession (1530), Article III
“truly suffered, was crucified, dead, and buried, that He might reconcile the Father unto us, and be a sacrifice, not only for original guilt, but also for all actual sins of men”

Reformed — Heidelberg Catechism (1563), Q&A 12
“God requires that his justice be satisfied. Therefore the claims of this justice must be paid in full, either by ourselves or by another.”
Heidelberg Catechism, Question & Answer 12
Presbyterian — Westminster Confession of Faith (1646), Chapter VIII
“The Lord Jesus, by his perfect obedience, and sacrifice of himself, which he, through the eternal Spirit, once offered up unto God, hath fully satisfied the justice of his Father”
Westminster Confession of Faith, Chapter VIII, Section 5

Study & Discussion Questions
- Ransom, satisfaction, penal substitution, moral influence, and governmental theory each emphasize a different biblical image (liberation, honor, punishment, love, government) for what the cross accomplishes. Which image do you find most compelling for making sense of Mark 10:45, and which feels most in tension with it?
- Romans 3:25's hilasterion has been translated both “propitiation” (appeasing wrath) and “expiation” (removing sin) by respected translations. How much does this single word choice change how you would explain what the cross accomplishes?
- Anselm rejected the ransom-to-the-devil imagery of the early church as beneath God's dignity, yet Colossians 2:15 and Hebrews 2:14-15 do describe Christ triumphing over hostile powers. How might a defender of Christus Victor respond to Anselm's objection?
- The governmental theory explicitly denies the strict one-to-one penalty transfer that penal substitution affirms, while still holding that Christ's suffering was necessary. What theological or pastoral difference might this distinction make in practice?
- Scholars like N. T. Wright argue the New Testament deploys multiple atonement images without resolving them into one systematic mechanism. Does treating these as complementary metaphors lower the stakes of deciding among them, or does the choice still matter?
