What Exactly Happened on the Cross?

One of the questions that has occupied my mind lately is this: what exactly do people think happened on the cross?

Not simply that Christ died for our sins. Every Christian confesses that.

I mean, what are you actually picturing? What transaction do you believe took place?

That question has become increasingly important to me because our understanding of salvation is inseparable from our understanding of Christ Himself.

If we begin with ourselves, the answer is obvious enough. We cannot make ourselves innocent. We cannot erase our guilt through good works, moral improvement, or religious devotion. None of these things remove our condemnation before God. Salvation belongs entirely to Christ.

But once we affirm that, another question immediately follows.

How does Christ save us?

The Penal Substitution Model

For many in the Reformed tradition, the answer is framed in terms of penal substitution. Christ receives the punishment that was due to us. He pays our debt. He satisfies divine justice.

That language raises a number of questions that I don’t think are often asked carefully enough.

What exactly was man’s punishment?

Was it merely bodily death?

Or was it death together with damnation? Was spiritual death itself part of what Christ endured?

If the punishment due to sinful man includes separation from God in the fullest sense, what does it mean to say Christ endured that punishment?

What Exactly Is Being Punished?

This is where I begin to struggle with the model.

Christ is one divine Person with two natures. He is not two subjects acting independently. Nor can the Trinity be divided against itself.

So what exactly is being punished?

If the divine Person is somehow abandoned or condemned by the Father, then we seem to introduce division into the Trinity itself. The eternal communion of Father, Son, and Holy Spirit becomes fractured precisely at the moment the Scriptures reveal God’s greatest work.

But if we instead say only Christ’s humanity experienced this punishment, then we begin dividing the one Christ into separate acting subjects, one capable of receiving divine wrath while the other remains untouched. The danger here is separating what Chalcedon insists must never be separated.

The more I think about it, the more I find myself asking whether this framework forces impossible choices. Either the unity of the Trinity is threatened, or the unity of Christ’s person is.

Neither option seems compatible with the faith confessed by the Ecumenical Councils.

St. John of Damascus on the Death of Christ

St. John of Damascus presents Christ’s death quite differently.

Christ truly dies.

His human soul is separated from His human body, just as occurs in every genuine human death. Yet the divinity remains united to both. The divine nature is not torn apart. The Person of Christ is not divided.

Then Christ descends into Hades.

Not as one condemned.

Not as one abandoned by the Father.

He descends as Life entering death itself.

He enters Hades in order to destroy it from within.

Death swallows Life and cannot contain Him.

Christ breaks its gates, frees its captives, and rises victorious.

The Descent into Hades

That picture has become increasingly compelling to me because it preserves everything the Church confesses about Christ while also taking seriously the ancient proclamation that “He descended into Hades.”

Interestingly, this descent often receives very little attention in many Protestant presentations of the gospel. The cross is emphasized, the resurrection is emphasized, but Christ’s victory over Hades itself is often left almost unexplored.

Yet the Fathers consistently saw it as essential.

Death is not merely forgiven.

Death is conquered.

Salvation as Healing, Not Acquittal

This also shapes how I think about salvation itself.

The goal of the Christian life is not simply having a legal sentence removed from a heavenly ledger. It is union with Christ.

Because Christ assumed our human nature, He heals it.

Because He entered death, He destroys its tyranny.

Because He rose, humanity itself is raised.

As St. Paul says, “As in Adam all die, so also in Christ shall all be made alive.”

The resurrection of Christ is not merely proof that His sacrifice was accepted. It is the beginning of the resurrection of humanity itself.

Every human being will rise because Christ has united Himself to our nature.

That does not mean every person enjoys eternal communion with God. The Church has never taught that. But it does mean the resurrection itself is universal because the God-man has conquered death for mankind.

A Difficulty for Limited Atonement

For me, that creates another difficulty for limited atonement.

If Christ’s assumption of human nature brings about the resurrection of all mankind, then His work already extends universally in a very real sense. The question is no longer whether Christ’s work reaches all humanity, but whether each person remains united to Him in faith, repentance, and participation in His life.

The more I study the Fathers, the less salvation looks like a courtroom where God changes His legal verdict while everything else remains the same.

Instead, salvation looks like a physician healing what was broken.

It looks like the Creator entering His own creation.

It looks like Life entering death.

It looks like Christ trampling down death by death.

That is a far richer picture than one of mere acquittal.

It is not simply that God declares us righteous.

It is that God, in Christ, enters death itself, destroys its power, restores our humanity, and invites us into communion with Him.

That is not merely a different explanation of the atonement.

It is an entirely different vision of what salvation is.
