Pelagius: Know the Heretics
In the early 5th century a debate arose between Pelagius, a British monk, and Augustine, the Bishop of Hippo in North Africa. They disagreed over the relationship between human nature after the Fall and saving, divine grace in Jesus Christ. When Pelagius arrived in Rome and saw the city’s dim view of morality, he developed a reputation for being a spiritual director who urged people to reform their behavior and live lives as upstanding, moral citizens.
Pelagius’ View of Sin
Pelagius rejected the doctrines of original sin, substitutionary atonement, and justification by faith. Pelagius emphasized unconditional free will and the ability to better oneself spiritually without grace. This was in direct contrast to Augustine, who believed that humanity was completely helpless in Adam’s sin and in desperate need of grace. Specifically, Pelagius took issue with Augustine’s prayer in his Confessions, which asked God to grant humans grace to act in accordance with his divine commands: “Grant what you command and command what you will.” (Confessions, X. 40).
Pelagius rejected the teaching of “original sin,” the results of the Fall upon humanity. According to him, Adam’s sin in no way made humans corrupt, but instead “over the years our sin gradually corrupts us, building an addiction and then holding us bound with what seems like the force of nature itself.” (Letter to Demetrias, VIII). Humans by nature have a clean slate, and it is only through voluntary sin that humans are made wicked. Potentially, then, one could live a sinless life and merit heaven. Pelagius thought that God commanding a person to do something that he lacked the ability to do would be useless: “To call a person to something he considers impossible does him no good.” (Letter to Demetrias, I). If God called humans to live moral lives, Pelagius thought, it should be within their power to carry out such commands.
Pelagius’ error was deemed heretical in 416 by the Council of Carthage. Originally Adam, Augustine said, possessed freedom—the ability not to sin. After the Fall, all human beings participate in Adam’s sin, which renders them not able not to sin. After the mediation of divine grace in Jesus Christ humans are once again given the ability not to sin. Augustine replied to Pelagius’ views in two treatises: On the Grace of Christ and On Original Sin. Augustine writes: “We must realize that Pelagius believes that neither our will nor our action is helped by divine aid…he believes that God does not help us to will, that he does not help us to act, that he helps us only to be able to will and to act.”(On the Grace of Christ, V.6). Augustine saw Pelagius’ teaching to be a clear denial of Philippians 2:12-13, because Pelagius located the capacity “to will and to do” what pleases God in human nature rather than in God’s grace.”(On the Grace of Christ, V.6 and VI.7).
Why Does All This Matter?
Ignoring the consequences the Fall has on everyone leads to a diminishment of the multifaceted work of Christ. In his ministry Jesus not only bore our sins on the cross, but lived a perfect life in obedience to the Father through the power of the Holy Spirit—the life that Adam failed to live—in order to restore fallen humans to their original state of grace. It is not only through the grace of God that humans are initially saved but also through this grace that they are sustained. As Augustine put it, God “guards the weak so that by his gift the saints unfailingly choose the good and unfailingly refuse to abandon it.”(On Rebuke and Grace, 38). Without understanding the magnitude of sin and the plight of humanity, the gracious work of Jesus for us and our salvation seems superfluous. 1 Peter 1:18-19 says: “You were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, but with the precious blood of Christ.” Because of sin, humans are not naturally good—that’s why we need Jesus.
