In what way are we saved? In what way are we reconciled to God? How is man redeemed? Irenaeus, a significant apologetic church father, attempted to answer these critical theological questions during his life and ministry. He was tutored by Polycarp of Smyrna, who taught him the traditions of the apostle John. Like many church fathers before him, Irenaeus spent the majority of his ministry opposing Gnosticism. This focus prompted many writings about salvation and redemption. In his Against Heresies, Irenaeus concludes that the Gnostic’s redemptive theology is nothing short of ridiculous, and he alternatively suggests his expression of redemption. Although Irenaeus’s critiques against the Gnostic belief played a significant role in the overall story of Christian theology by exposing it as heretical through biblical and apostolic standards, his real contribution lies in this alternative redemptive vision to Gnosticism: “The Theory of Recapitulation.”
The Term’s Origin
The word “Recapitulation” comes from the Latin term capitus, which means “head.” Irenaeus himself likely used the Greek term anakephalaiosis, which means “reheading” or “to provide a new head.” Of course, Irenaeus was not using this term in the literal sense but instead as the origin or root of something. To “provide a new head” wasn’t giving someone a new head on the body; it was giving someone a new identity. In Against Heresies, he presents what he believed to be the apostolic, and therefore authoritative, Christian teaching about Christ’s work of redemption as the new “head” of humanity–recapitulation.
Irenaeus created this theory in response to the Gnostic theology of redemption. The Gnostics disregarded and denied the incarnation as a means of theological significance. Instead, they thought of Christ’s work as entirely and purely spiritual; Christ redeems those who have the capacity for greater spiritual knowledge or gnosis. In either sect of Gnostic theology, Christology or soteriology, Christ’s work did not require an incarnation. When Jesus was crucified, the pure spirit of Christ was not in or near him. The human aspect of Jesus Christ was merely the “host” of Christ’s spirit and played no role in the redemption of humanity.
Theological Importance of the Incarnation
For Irenaeus, the incarnation was entirely necessary for redemption and salvation. Incarnation, the eternal Son of God becoming human–the Logos experiencing human existence–was what redeems and restores fallen humanity. If Jesus Christ was not both truly Jesus and truly Christ, salvation is therefore incomplete and impossible. If the incarnation of Christ did not happen, the saving gospel is lost. The incarnation itself, expounded upon by Irenaeus’s theory, is transformative. Anakephalaiosis, recapitulation, was his theological understanding of how the physical incarnation of the Logos, the “Word” or Son of God, in Jesus works to transform humanity. Literally, the human race is “born again” through the incarnation. In the background of Irenaeus’s thinking was Paul’s reflections on Adam and Christ in Romans 5. Christ is the “second Adam” of the human race, and in him “God recapitulated in Himself the ancient formation of man [Adam], that he might kill sin, deprive death of its power, and vivify man and therefore His works are true” (Against Heresies). For Irenaeus,
If man is to be saved, it is necessary that the first man, Adam, be brought back to life, and not simply that a new and perfect man who bears no relation to Adam should appear on the earth. God, who has life, must permit His life to enter into “Adam” the man who truly hungers and thirsts, eats and drinks, is wearied and needs rest, who knows anxiety, sorrow and joy, and who suffers pain when confronted with the fact of death.Gustaf Wingren, Man and the Incarnation: A Study of Biblical Theology of Irenaeus, pp. 95-96
In the incarnation, the Word, Christ Jesus the Logos, took on the physical source of humanity–the body of Adam–and lived the reverse of Adam’s life. The first Adam, as Romans 5 states, lived in disobedience to God in the Garden of Eden. Humanity, as a result, is descended from the sinfulness of the first Adam. According to Irenaeus, to reverse the consequences of the Fall and renew humanity that fell because of Adam, the Word had to live in Adam’s flesh and live the reverse of Adam’s life in perfect obedience to God. Where Adam failed, the incarnate Word as the second Adam succeeded and reconciled the world back to the Father.
The crux of Christ’s accomplishment of redeeming humanity came when he was tempted in the wilderness by Satan. When Satan came into the Garden of Eden, man was conquered and fell into depravity before God. When Satan came again to Adam, which was in Christ, Satan was conquered, and humanity achieved victory and regained life through the working redemption set forward by Christ. Furthermore, if the temptation was the crux, then the cross and resurrection were the culmination of Christ’s recapitulating work. Adam’s death was a result of his disobedience to God, whereas Christ’s death was in obedience to God, therefore providing the new head.
In direct opposition to the Gnostic belief, Irenaeus strived to expound the work the Apostle Paul introduced in the book of Romans. Rather than dismissing the idea of the incarnation, Irenaeus noted that the Logos becoming human is what redeems us. He, and many church fathers after him, perceived the threat against the incarnation as a threat to our very mechanism of salvation. Those who participate in Christ’s new humanity must put off the sin of the first Adam. By receiving the “new head” through the work of Christ, they also receive the transformative power made possible by the incarnation of the Son of God, which is our initial means of becoming redeemed.
