What happened on the cross? (Theories of atonement)
Question 7100
What exactly happened when Jesus died on the cross? Christians have always agreed that the cross is central to salvation, but they have understood its meaning in different ways throughout history. Various “theories of the atonement” have been proposed, each highlighting a different aspect of what Jesus accomplished. Some of these theories are faithful to Scripture; others fall short. Understanding them helps us appreciate the full richness of what Jesus did for us.
Penal Substitutionary Atonement
This view holds that Jesus bore the penalty that our sins deserved. He took our place under God’s wrath. He was punished so that we might go free. This is the understanding most clearly taught in Scripture and most central to evangelical faith.
Isaiah 53 lays the foundation: “Surely he has borne our griefs and carried our sorrows… he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed… the LORD has laid on him the iniquity of us all… it was the will of the LORD to crush him; he has put him to grief” (Isaiah 53:4-6, 10). The language is unmistakable. Our sins were placed on Jesus. He was crushed for our iniquities. The punishment came upon Him.
The New Testament confirms this repeatedly. “Christ redeemed us from the curse of the law by becoming a curse for us” (Galatians 3:13). “For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God” (2 Corinthians 5:21). “He himself bore our sins in his body on the tree” (1 Peter 2:24). Jesus was not simply a martyr or an example. He was bearing something, carrying something, becoming something on our behalf. He took the curse. He became sin. He bore our sins.
Your Soteriology notes capture this vividly. Jesus died twice: “physically and spiritually. The sin of the world upon Jesus. When God sees sin and has to move away. Bearing the sins of the whole world on the tree. Why have you forsaken me?” Those three hours of darkness were the hours when Jesus endured the Father’s wrath against sin. He was cut off from fellowship with the Father so that we would never be cut off.
This is the heart of the Gospel. As John Walvoord wrote, “The substitutionary death of Christ is the central fact of Christianity. All other aspects of His work depend upon it.”
Ransom Theory
This view emphasises that Jesus paid a ransom price to set us free from bondage. Jesus Himself said, “The Son of Man came not to be served but to serve, and to give his life as a ransom for many” (Mark 10:45). Paul wrote that “there is one God, and there is one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all” (1 Timothy 2:5-6).
The Greek word for ransom (λύτρον, lytron) refers to the price paid to release a slave or prisoner. We were slaves to sin, bound in chains we could not break. Jesus paid the price to set us free. Your notes explain: “Lutroo – Ransom. Held by a force you cannot get free from. I’ll pay the ransom. Exagorazo – Out from, market place or forum. Slaves were sold there. To buy out from the slave market.”
The early church sometimes speculated about to whom the ransom was paid. Some suggested it was paid to Satan, who held humanity captive. But this is mistaken. Satan has no rightful claim on us that God must honour. The ransom was not paid to Satan but to God’s justice. The demands of God’s holy law had to be satisfied, and Jesus satisfied them.
Christus Victor
This view sees the cross as Jesus’ victory over Satan, sin, death and all the powers of evil. Through His death and resurrection, Jesus defeated the enemies that held humanity captive. Colossians 2:15 declares that on the cross, Jesus “disarmed the rulers and authorities and put them to open shame, by triumphing over them in him.”
Hebrews 2:14-15 states that Jesus shared in flesh and blood “that through death he might destroy the one who has the power of death, that is, the devil, and deliver all those who through fear of death were subject to lifelong slavery.” The cross looked like defeat, but it was actually victory. Satan thought he had won when Jesus died, but in dying, Jesus was crushing the serpent’s head (Genesis 3:15).
Your notes capture this beautifully: “Crush his head – it is finished. The venom was put on Jesus… All the venom was taken out.” On the cross, Satan’s power was broken. Death was defeated. Sin’s dominion was ended. The resurrection proved the victory. Jesus is the conquering King.
Christus Victor is not an alternative to penal substitution; it is its result. Because Jesus bore our sins and satisfied God’s justice, the enemy’s accusations against us are silenced. Satan can no longer condemn us because the penalty has been paid. Victory flows from substitution.
Satisfaction Theory
Developed by Anselm of Canterbury in the eleventh century, this view emphasises that sin dishonours God and demands satisfaction. Human beings owe God a debt of honour they can never pay. Jesus, as the God-man, paid that debt on our behalf, satisfying God’s honour and restoring the moral order.
Anselm’s insights contain much truth. Sin does dishonour God. Jesus did satisfy what was owed. However, the biblical emphasis is not primarily on honour but on justice and wrath. God’s wrath against sin is not wounded pride but righteous judgment. Penal substitution better captures the biblical picture than satisfaction theory alone, though the two are related.
Moral Influence Theory
Proposed by Peter Abelard in the twelfth century and popular among theological liberals today, this view holds that the cross primarily functions as a demonstration of God’s love designed to inspire us to repent and live better lives. Jesus did not pay any penalty or bear any wrath. He simply showed us how much God loves us, and this example transforms us.
This theory contains a grain of truth. The cross certainly demonstrates God’s love (Romans 5:8). But it is utterly inadequate as an explanation of what happened. If Jesus was merely an example, why did He have to die? Why the agony of Gethsemane? Why the cry of dereliction? Why the emphasis throughout Scripture on blood, sacrifice and substitution? The moral influence theory strips the cross of its power and leaves us without an actual remedy for sin.
Charles Ryrie observes: “If Christ did not actually bear the penalty for sin, then the sinner is left to bear it himself. A demonstration of love, however moving, does not pay the sinner’s debt or satisfy God’s justice.”
Governmental Theory
This view, associated with Hugo Grotius (seventeenth century), holds that Jesus’ death was not a direct payment for sin but a demonstration that God takes sin seriously. God, as the moral governor of the universe, could not simply overlook sin. Jesus’ death shows that sin has consequences and upholds the moral order, thereby making forgiveness possible.
Again, there is partial truth here. God does govern the universe morally. Jesus’ death does display God’s righteousness. But the governmental theory falls short because it denies actual substitution. Jesus was not merely demonstrating something; He was accomplishing something. He was actually bearing sins, not just displaying their seriousness.
The Biblical Picture
Scripture gives us multiple images of the atonement because its riches are too great to be captured by any single image. Jesus is the sacrificial Lamb whose blood covers sin (John 1:29). He is the scapegoat who carries sins away (Leviticus 16). He is the kinsman-redeemer who pays the price to restore His people (Ruth). He is the ransom that frees slaves. He is the propitiation that turns away wrath. He is the victor who defeats the enemy. He is the suffering servant who bears iniquities.
All these images come together at the cross. They are not competing theories but complementary truths. At the centre of them all stands penal substitution: Jesus took our place and bore our punishment so that we might receive His righteousness and live forever. This is the Gospel. This is what happened on the cross.
Conclusion
The cross is an inexhaustible mystery. Theories of atonement help us understand different facets of what Jesus accomplished. Penal substitution stands at the heart: Jesus died in our place, bearing God’s wrath against our sin. From this flows ransom (we are bought out of slavery), victory (the enemy is defeated), and satisfaction (God’s justice is fulfilled). Theories that deny substitution, like the moral influence and governmental theories, ultimately empty the cross of its saving power. But when we understand what Jesus actually did, we can only fall on our faces in gratitude and worship the Lamb who was slain for us.
