The Rationale of the Atonement

We have already established, on solid historical grounds, that Jesus of Nazareth taught that His death on the cross has a unique relation to human salvation. Through that death, God receives into His favor, in spite of their past sins, all who believe the good news Christ proclaimed. Christ chose to die for this purpose, and the need for so costly a means of salvation arose from human sin. Paul drew from Christ's teaching the further conclusion that this necessity rested in the justice of God, and we have found that this conclusion best explains the teaching reflected throughout the New Testament. In the future, we shall consider historical evidence that the Crucified One claimed to be, in a sense shared by no other, the Son of God, the eternal companion of the Father's glory, the possessor of divine attributes, and the Creator and Judge of the world. And further, we shall consider historical evidence that this Savior of the world rose from the dead. Teaching about His own death, coming from such a Teacher and supported by such credentials, carries an authority we cannot dismiss. When our argument is complete, it will yield a settled conclusion to our theological inquiry.

Other New Testament Teaching on the Death of Christ

Now that we’ve looked at what Paul and the Epistle to the Hebrews say about the death of Christ, it’s time to compare that with what Christ Himself says about His death in the four Gospels.

One of the most striking moments in the Synoptic Gospels appears in the account found in Matthew 16:13–28, Mark 8:27–9:1, and Luke 9:18–27. Jesus takes His disciples away from the busy centers of life — to the remote regions near Hermon — so He can share deeper truths with them. But before introducing anything new, He checks what they’ve already understood. He asks, “ Whom do men say that I am?” Peter speaks for the group: “Thou art the Christ, the Son of the living God.”

The Epistle to the Hebrews on the Death of Christ

Closely connected to Paul’s letters, yet almost certainly written by someone else, the Epistle to the Hebrews stands as one of the most striking and instructive writings in the New Testament. What makes it especially notable is how directly and powerfully it presents the death of Christ as the divinely intended means by which humanity is saved from sin — even more explicitly, in some ways, than Paul’s own writings.

Reconciliation to God

One of Paul’s most distinctive teachings about the death of Christ — something especially associated with him and logically flowing from what we have already seen — is the idea that Christ’s death brings about reconciliation to God. This theme shows up clearly in passages where Paul speaks of Christ’s death as restoring peace between God and humanity.

In Romans chapter 5, verse 1, Paul pulls together his earlier teaching — especially Romans chapter 3, verses 22–26 — and describes its outcome as “peace with God through Christ,” a peace that comes from “being justified by faith.” Later in that same chapter, verse 10 restates the argument of verse 9 by saying that believers have been “reconciled to God through the death of His Son,” treating this as another way of saying that they have been “justified in His blood.” Then, in verse 11, Paul adds, “through whom we have now received the reconciliation.”

The Teaching of Paul on the Death of Christ

Another major strand of New Testament teaching — one that Paul closely connects with his central doctrine of justification by faith — now calls for our attention. This teaching helps address a serious moral problem: how God can pardon guilty people while remaining righteous. Both Christ and His apostles proclaim forgiveness, but Paul presses us to see how this forgiveness is grounded in something much deeper.

After announcing in Romans 3:21–22 a “righteousness … through faith in Christ for all who believe,” Paul continues in verse 24 by saying that believers are “justified … through the redemption that is in Christ Jesus.” He immediately expands on this idea of redemption by adding that God put Christ forward “as a propitiation through faith, in His blood.” These words clearly highlight the violent death of Christ as a central element of the redemption accomplished in Him.
Paul explains the ultimate purpose of this act: it served as a demonstration of God’s righteousness, so that God might remain righteous while also justifying those who have faith in Jesus. In short, God gave Christ over to death in order to bring human justification into harmony with His own righteous character.
