There is a verse in Romans 5 where Paul names the situation the cross addresses with characteristic bluntness.
“For if while we were enemies we were reconciled to God through the death of his Son, how much more, since we have been reconciled, will we be saved by his life?” (Romans 5:10, NET)
Notice what Paul calls us in that verse. Enemies. Not the lapsed friends of God who needed restoring. Not the wandering children who needed coaxing back. Enemies — echthroi — the word for opponents at war, for the kind of opposition that produces casualties. That was what we were when Christ died for us.
And notice what God did with His enemies. He reconciled us. Not negotiated terms. Not waited for surrender. Not made peace through diplomacy. He reconciled us through the death of His Son. The Greek word for what He did is katallagē — reconciliation, exchange, the changing of one relational state for another. The relationship between God and His enemies was changed at the cross. The wrath was borne. The enmity was ended. The peace was made — by Him, for us, while we were still His enemies.
This is the entry on katallagē, and the central point is one English usage can obscure: in the New Testament’s reconciliation, the one who reconciles is God, and the one who is reconciled is us. Never the other way around.
The Word
καταλλαγή (katallagē), pronounced ka-tal-la-GAY. A feminine noun, first declension. The family includes the verb katallassō (καταλλάσσω, “to reconcile, to exchange”) and Paul’s intensive compound apokatallassō (ἀποκαταλλάσσω, “to reconcile thoroughly, to bring into full reconciliation”). The root is allassō (ἀλλάσσω), “to change, to alter, to exchange,” and the kata- prefix gives the action a thorough or completed character.
The etymology is worth knowing. In ordinary Greek usage, allassō and its derivatives could describe the exchange of one currency for another — what a money-changer did. By extension, the verbs came to describe the exchange of one state of affairs for another, especially in human relationships: enmity exchanged for friendship, hostility for peace, separation for restored communion. When Paul reaches for katallagē to describe what God has done in Christ, he is reaching for a word that meant something like “the transaction by which one state is thoroughly exchanged for another.”
The transaction is the cross. The estrangement that sin produced between God and sinners is exchanged for peace. The wrath of God against sin (Hilastērion) is exchanged for restored relationship. The separation between humans and God that runs from Genesis 3 forward is exchanged, in Christ’s death, for friendship. The exchange happens in one direction — God to us — but the result is mutual: God now has friends where He had enemies, and we now have a Father where we had a Judge.
Range of Meaning
In its New Testament usage, katallagē and its verbal forms cover:
- Reconciliation between estranged parties, in the general human sense. Used once by Paul in this sense (1 Cor 7:11, of estranged spouses).
- The reconciliation God has accomplished between Himself and sinners through Christ’s death. The dominant theological use, especially in Paul’s letters.
- The cosmic reconciliation that includes “things on earth or things in heaven” (Col 1:20, NET).
- The apostolic “ministry of reconciliation” — the proclamation by which God’s reconciling work in Christ is announced to those who do not yet know they have been reconciled.
The center of gravity is the second sense — God’s reconciliation of sinners to Himself through the cross. Every major use in Paul’s atonement passages runs on this track. The reconciliation is the work; the cross is the means; the recipients are sinners; the result is peace with God.
Where You’ll Meet It
“Not only this, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received this reconciliation.” (Romans 5:11, NET)
Paul’s compressed statement of the believer’s posture: we rejoice in God because we have received reconciliation. The verb is labontes — taking, receiving. Reconciliation is not something we accomplish. It is something we receive. The Lord Jesus Christ is the means; God is the source; we are the recipients; rejoicing is the response.
“And all these things are from God who reconciled us to himself through Christ and who has given us the ministry of reconciliation. In other words, in Christ God was reconciling the world to himself, not counting people’s trespasses against them, and he has given us the message of reconciliation. Therefore we are ambassadors for Christ, as though God were making his plea through us. We plead with you on Christ’s behalf, ‘Be reconciled to God!’” (2 Corinthians 5:18–20, NET)
The most concentrated passage on reconciliation in the New Testament. Worth slowing down through it. And all these things are from God: the initiative is divine. who reconciled us to himself through Christ: the means is Christ’s work; the direction is us-to-God. Not counting their trespasses against them: the legal-forensic dimension of reconciliation, which connects to dikaioō. The message of reconciliation: the apostolic proclamation. We are ambassadors: the messengers, but the message is God’s. Be reconciled to God: the appeal to those who do not yet know they have been reconciled, calling them to receive what God has already done.
“For God was pleased to have all his fullness dwell in the Son and through him to reconcile all things to himself by making peace through the blood of his cross—through him, whether things on earth or things in heaven.” (Colossians 1:19–20, NET)
The cosmic scope. The verb is the intensive apokatallassō. The reconciliation is universal in its accomplishment — “things on earth or things in heaven.” This does not mean universal salvation (we will treat this below) but does mean that the cross’s reach extends beyond the individual believer to the cosmic restoration of all things in Christ. Notice how the verse brings these Greek terms together: the plērōma dwells in Christ, the eikōn of the invisible God; through Him the reconciliation is accomplished; by the haima of the cross. One Christ, one work, named through multiple words.
“and to reconcile them both in one body to God through the cross, by which the hostility has been killed.” (Ephesians 2:16, NET)
Paul’s application of katallagē (here the verb apokatallassō) to the Jew-Gentile question. The cross does double work: it reconciles Jew and Gentile to God, and in doing so it also reconciles them to each other in one body. The horizontal reconciliation between humans is real and important, but it is downstream of the vertical reconciliation between humans and God. The cross accomplishes both.
“And you were at one time strangers and enemies in your minds as expressed through your evil deeds, but now he has reconciled you by his physical body through death to present you holy, without blemish, and blameless before him—” (Colossians 1:21–22, NET)
The personal application of what the previous verses established cosmically. You were alienated. You were hostile in mind. You were doing evil deeds. And you have been reconciled — by Christ’s body of flesh, by His death — and the result is that you will be presented holy and blameless before God. Paul connects the reconciliation (objective, accomplished) to the believer’s eschatological presentation (future, certain) in one breath.
What Confessional Lutherans Hear
Two things ring in Lutheran ears when we hear katallagē.
First, God is the reconciler, not the reconciled. The direction of reconciliation in the New Testament is consistent. God reconciles us to Himself; we do not reconcile God to ourselves. Every major passage carries this direction:
- 2 Cor 5:18 — God “reconciled us to himself.”
- 2 Cor 5:19 — God “was reconciling the world to himself.”
- Rom 5:10 — “we were reconciled” — the passive voice, with God as the agent.
- Col 1:20 — Christ reconciles “to himself” — that is, to God in His own person.
The grammar refuses to budge. God is the one acting; sinners are the ones being acted upon. The reconciliation is God’s verb. We are God’s object.
This is theologically consequential. In ordinary human reconciliation, both parties typically have to change. The husband and the wife both move toward each other. The estranged friends each apologize. The treaty between nations requires terms acceptable to both sides. Human reconciliation is, by its nature, mutual. Divine-human reconciliation, in the New Testament, is not. The change happens on the human side experientially — we who were enemies are now friends; we who were dead are now alive; we who were far off are now near (Eph 2:13). But the act of reconciling is entirely God’s. He did not need our permission. He did not wait for our willingness. He did not require our half of the work. He reconciled us to Himself through the cross, while we were enemies, before we knew what was happening.
There is, of course, a sense in which God’s wrath against sin had to be addressed — and the Hilastērion entry treated this. The propitiation accomplished at the cross deals with the divine side of the obstacle, in that the wrath that justice required has now been borne. But notice how the New Testament describes even this: it is God Himself who provides the propitiation, God Himself who sent His Son to be it (1 John 4:10), God Himself who is both just and the justifier (Rom 3:26). The whole movement is from God. The propitiation does not enable God to be willing to reconcile; the propitiation is the means by which the God who has always loved us removes the obstacle that His own holiness required to be removed. The wrath was real. The love was real. The cross resolved them — by God’s own act, in His own Son, on His own initiative.
Second, reconciliation is rooted in the cross, not in human moral progress. Romans 5:10 is the verse to memorize: “For if while we were enemies we were reconciled to God through the death of his Son, how much more, since we have been reconciled, will we be saved by his life?” Not “after we improved ourselves.” Not “when we showed willingness to be reconciled.” Not “when we met God halfway.” While we were enemies. The cross is the reconciling act, performed on enemies, before any change on the human side could have contributed to it.
This is the doctrine that grounds Lutheran assurance. If reconciliation depended on our moral progress, our cooperation, our willingness — we could never be sure where we stood. We might have done enough; we might not have. We might be reconciled today; we might not be tomorrow. Because reconciliation is the work of Christ on the cross, accomplished while we were still enemies, the believer’s standing is grounded outside himself. The peace has been made. The reconciliation is done. Faith does not produce the reconciliation; faith receives the reconciliation God has already made.
The pastoral payoff: when you wonder whether God is reconciled to you, the question is misframed. God reconciled you to Himself. He did not need to be reconciled to you. The cross was the act by which He addressed your enmity at His own cost, in His own Son, before you knew you were the kind of person who needed it. You receive the reconciliation in the gospel preached, the absolution declared, the water poured, the bread broken. The reconciliation is given. The peace was made.
Where People Get It Wrong
Three common ways.
The first is treating reconciliation as a mutual process. As discussed above, the New Testament refuses this picture. God reconciles; we are reconciled. The direction is fixed. Some modern theologies, perhaps influenced by relational therapy or by analogies from human conflict resolution, picture divine-human reconciliation as a bilateral negotiation in which God moves toward the sinner and the sinner moves toward God and the relationship is restored when they meet. This is not the New Testament’s picture. The New Testament’s picture is that God did the moving. The cross was the move. The sinner who receives the reconciliation is not contributing to it; the sinner is receiving what God accomplished while the sinner was unable to contribute anything.
The second is divorcing reconciliation from the cross. This is a more recent move, especially common in progressive Christian discourse. “Reconciliation” becomes a moral-political program — racial reconciliation, social reconciliation, interfaith reconciliation — without grounding in the atonement that the New Testament makes the source. The Lutheran response is not that interhuman reconciliation is unimportant; it is important, and Ephesians 2:16 makes clear that the cross has direct implications for it. The response is that katallagē in the New Testament’s primary use names the vertical reconciliation between God and sinners, and the horizontal reconciliation flows from that source. Cut off from the cross, “reconciliation” language can become a moral aspiration without theological substance. Connected to the cross, it has the resources actually to accomplish what it names.
The third is universalism — the inference from “in Christ God was reconciling the world to himself” (2 Cor 5:19, NET) that all individuals will ultimately be saved regardless of faith. Paul’s own grammar refuses the inference. The same passage that announces cosmic reconciliation also issues the apostolic appeal: “We plead with you on Christ’s behalf, ‘Be reconciled to God!’” (2 Cor 5:20, NET). The appeal would be unnecessary if the cosmic reconciliation automatically secured every individual’s salvation. The New Testament’s pattern is that the objective work of reconciliation has been accomplished for the world (universally, through the cross), and the subjective reception of that reconciliation comes through faith. The two are not the same. Confessional Lutheran theology has consistently held both: Christ died for all (objective universal accomplishment) and the saving benefit is received by faith (subjective particular reception). Universalism collapses the second into the first; particular redemption (some Reformed versions) limits the first to the second. Lutherans hold both as the New Testament gives them.
So What
The cross is where God reconciled the world to Himself. The reconciliation is accomplished. The peace is made. What remains is for the gospel to deliver this to each person, one by one, that they may receive what God has already done.
For Sunday school teachers and Bible study leaders: when you teach a passage on reconciliation, watch the direction. God reconciles us to Himself. We do not reconcile God to ourselves. We do not reconcile ourselves to God by our own moral effort. We receive the reconciliation God has already accomplished. The “be reconciled to God” of 2 Corinthians 5:20 is not a moral command to bridge the gap to God by our own effort; it is the apostolic appeal to receive what God has already done. Your students will often hear “reconciliation” through the lens of human conflict-resolution, where the moves are bilateral. Help them hear it the way Paul wrote it.
For yourself: when you wonder where you stand with God, remember the timing of His reconciling work. While you were His enemy. Before you knew you needed reconciliation. While you were doing nothing to deserve it. That is the kind of reconciliation the cross accomplished. Your continuing standing is on the same ground — not earned, received. The peace has been made. The God who made it does not unmake it. Your faith is the empty hand (Pistis) that takes what He has offered.
