“The Reconciler, Not the Reconciled”
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 by the death of his Son, much more, now that we are reconciled, shall we be saved by his life.” (Romans 5:10, ESV)
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 chapter 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 (Chapter 20 on 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 “all things, whether on earth or in heaven” (Col 1:20).
- 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
“More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.” (Romans 5:11, ESV)
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.
“All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation; that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God.” (2 Corinthians 5:18–20, ESV)
The most concentrated passage on reconciliation in the New Testament. Worth slowing down through it. All this is from God: the initiative is divine. Through Christ reconciled us to himself: 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 (Chapter 19). 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 in him all the fullness of God was pleased to dwell, and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross.” (Colossians 1:19–20, ESV)
The cosmic scope. The verb is the intensive apokatallassō. The reconciliation is universal in its accomplishment — “all things, whether on earth or 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. Worth noting how the verse layers chapters of this book together: the plērōma (Ch 6) dwells in Christ, the eikōn (Ch 5) of the invisible God; through Him the reconciliation is accomplished; by the haima (Ch 33) of the cross. One Christ, one work, named through multiple words.
“And might reconcile us both [Jew and Gentile] to God in one body through the cross, thereby killing the hostility.” (Ephesians 2:16, ESV)
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, who once were alienated and hostile in mind, doing evil deeds, he has now reconciled in his body of flesh by his death, in order to present you holy and blameless and above reproach before him…” (Colossians 1:21–22, ESV)
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
Katallagē — reconciliation
We hear katallagē with two emphases the broader Christian conversation often softens.
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 previous chapter on hilastērion 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: “while we were enemies we were reconciled to God by the death of his Son.” 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.
