What the first Christians believed about the cross

For the first thousand years of Christianity, the church described the cross as a rescue: God entered death itself to destroy it from the inside. Penal substitutionary atonement, the version most Western Christians grew up with, where you sinned, God is just, and Jesus took the punishment you deserved, has ruled Protestant theology for centuries. But it was never the early church’s primary framework, and the older vision answers questions the guilt-and-payment model struggles with.

That difference matters because the hardest skeptical critiques of Christianity tend to target the narrow version. “He was only dead for a day and a half.” “Anyone would take that deal.” “The system runs on guilt.” Objections like these land against a cross framed as a transaction and measured by suffering, and the early fathers were measuring something else entirely. In this episode Nate traces their bigger vision through Irenaeus, Athanasius, and two Gregorys.

Irenaeus and the whole life of Christ

Irenaeus, born around 130 AD, was a student of Polycarp, who personally knew the apostles. The vision of redemption he laid out, which he called recapitulation, holds that Christ relived the human story and got right what Adam got wrong. Adam was created to grow into the image of God but grabbed at it too soon. Christ walked the same path patiently, through every stage of human life.

The striking part is that Irenaeus didn’t treat the death alone as the saving act. The entire life of Christ, from birth to grief to weariness to death, was God entering every dimension of human experience to heal it from within. Nate puts the contrast this way in the episode:

“The problem isn’t ‘you did bad things and you need to feel guilty.’ The problem is that humanity is stuck in a condition of death, and a good person dies just as surely as a bad one. The solution isn’t legal payment. It’s a rescue.”

That reframing changes how the hardest questions land. If the human problem is death and alienation from God rather than a courtroom debt, then the cross is measured by who walked into it, not by how much pain it involved.

Athanasius and the death of the deathless God

About 150 years after Irenaeus, Athanasius of Alexandria wrote On the Incarnation, one of the most important works in Christian history. Its most famous line captures the early church vision in a single sentence: “He was made man that we might be made God.” Not that humans become separate gods, but that humanity is brought back into communion with divine life, pulled out of death and into what it was always meant for.

Athanasius also supplies one of the strongest answers to the “he was only dead for a day and a half” critique. For him the scandal of the cross was never the duration or intensity of the suffering. The one who is life experienced death at all, and that is the event that should be impossible. The episode reaches for an analogy:

“If someone told you a fire was burning underwater, the first thing you would ask probably isn’t ‘how long has it been burning?’ The first thing you’d ask is ‘how is that even possible?’ That’s how Athanasius sees the cross.”

A deathless God tasting death shouldn’t happen. Duration is beside the point.

What has not been assumed has not been healed

Gregory of Nazianzus, Archbishop of Constantinople in the fourth century, gave the church one of its most enduring theological principles: “What has not been assumed has not been healed.” If human minds are fallen, Christ needs a human mind to heal them. If human emotions are broken, Christ needs human emotions. If death is the problem, Christ has to die.

Follow that logic and the incarnation itself, from birth to crucifixion, becomes where the saving happens. The cross is the climax, but the whole life matters. Every part of Christ’s human experience is God reaching into a broken place and remaking it.

Christus Victor, the framework of the first thousand years

Scholars call this broader vision Christus Victor, “Christ the victor.” The term comes from Gustaf Aulén’s landmark 1931 study Christus Victor, which traced how Christians have understood the cross across history. Aulén argued, and many scholars since have agreed, that the victory framework was the most consistent way the early church described what Christ accomplished, in both the Greek-speaking East and the Latin-speaking West.

In this picture the cross works less like a payment and more like a trap. Christ entered the territory of death and defeated it from within. Gregory of Nyssa described it with an image that sounds wild but shows how the early fathers thought: Christ’s humanity was like bait on a fish hook. Death swallowed a human being, the way it swallows everyone, but hidden inside that humanity was divinity. Death choked on it and was destroyed from the inside.

The ancient Christian hymn still sung in Orthodox churches today captures it: “Christ is risen from the dead, trampling down death by death, and upon those in the tombs bestowing life.”

Why the bigger picture matters

The critiques that feel devastating against a guilt-and-payment-only gospel lose their force inside the wider one. “Anyone would take that deal” misses the point when the cross reveals divine character rather than creating a debt. “The model works best for the worst people” falls apart when the human problem is a universal condition of death that claims good and bad people alike, rather than a ledger of personal guilt.

None of this makes penal substitution a lie. There is substitutionary language in the New Testament, and Paul writes about it. But what most Western Christians were taught as the gospel, the one framework and the whole point, is a piece of a much larger picture, and a piece that didn’t become dominant until well over a thousand years after Jesus.

The earliest Christians held something richer. The gospel they proclaimed wasn’t “you’re terrible, now feel grateful.” It was “you’re dying, you’re trapped in a decaying world, and God has broken into the prison. You’re invited into a whole new kind of life.” The response that message asks for is participation, not guilt.

If you’ve carried honest questions about the cross that nobody around you could answer well, it might not be your faith that’s too weak. It might be that the framework you were handed is too small. The first Christians had a much bigger one.

Common questions

What did the early church believe about the atonement?

For roughly the first thousand years, Christians most consistently described the cross as victory over death rather than a legal payment for guilt. Fathers like Irenaeus, Athanasius, and the two Gregorys taught that God entered human life, and death itself, to heal humanity from within and destroy death from the inside.

What is Christus Victor?

Christus Victor, “Christ the victor,” is the scholarly name for that victory framework, taken from Gustaf Aulén’s 1931 study of how Christians have understood the cross. Aulén argued it was the early church’s most consistent way of talking about the atonement, in both the Greek-speaking East and the Latin-speaking West.

Is penal substitution unbiblical?

No. The New Testament contains substitutionary language, and Paul writes about it. The early church’s witness suggests it is one piece of a much larger picture rather than the whole gospel, and it didn’t become the dominant framework until well over a thousand years after Jesus.

Does it matter that Jesus was only dead for a day and a half?

In the early church’s framework, no, because the point was never how long or how intensely Jesus suffered. Athanasius located the scandal in the fact that the one who is life experienced death at all, the way a fire burning underwater is shocking for existing rather than for how long it burns.
