What are Pelagianism and Semi-Pelagianism?

from the old testament

• When Adam disobeyed God, judgment followed immediately, bringing both physical death and spiritual separation from God (Genesis 2:17; 3:17–19). Adam’s sin did not remain isolated to him alone. Instead, it introduced corruption into the human condition, so that death became the universal destiny of mankind. The spread of death testifies that sin now marks every human life, showing that humanity stands under judgment because of Adam’s transgression.
• Corruption has been passed on to all as it is present from the very beginning of life. David confessed this, saying, “Behold, I was brought forth in iniquity, and in sin did my mother conceive me” (Psalm 51:5). David was not referring to his conception being the result of sin, but acknowledging that sinfulness is part of human nature from conception. This verse directly contradicts the Pelagian idea that people are born morally neutral and capable of choosing what is good on their own.
• This is why Scripture describes sin as universal. For example, in Psalm 14, God is pictured as looking over the entire earth “to see if there are any who understand, who seek after God,” declaring that He finds none because “there is none who does good, not even one” (Psalm 14:1–3).

from the new testament

• Unlike what Pelagianism and Semi-Palagianism claim, Scripture teaches that humans are unable to choose God. For example, Paul described all people as “dead” in trespasses and sins (Ephesians 2:1–3). Spiritual death is not moral neutrality or simple sinful weakness. Just as the physically dead can do nothing, the spiritually dead cannot respond to God.
• Elsewhere, in Romans 3, Paul gathered Old Testament passages to show that no one is righteous, no one understands, and no one seeks God (Romans 3:10–18). All men and women, universally “have sinned and fall short of the glory of God” (Romans 3:23).
• Paul explained the origin of this condition. In Romans 5, he argued that through one man, Adam, sin entered the world, and death spread to all because all sinned in him (Romans 5:12–19). Paul’s argument is essential to understanding the Gospel. As Adam’s sin corrupted all, Jesus’ sacrifice saved all.Without corruption, there would be no need for salvation. Pelagianism and Semi-Palagianism, at their root, base salvation on human effort rather than Christ’s work.
• Because humanity is completely corrupted and born spiritually dead, salvation is impossible unless God intervenes. Arguing against the false spiritual leaders of His time, Jesus taught, “No one can come to me unless the Father who sent me draws him. And I will raise him up on the last day” (John 6:44). No one has the ability, outside of God’s work, to be saved.
• We are saved because God takes the initiative and makes us alive: “But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved” (Ephesians 2:4–5). Later in Ephesians 2, Paul writes, “For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast” (Ephesians 2:8–9).
• Pelagianism and, to a lesser degree, Semi-Pelagianism give human ability more credit for salvation than Scripture allows. By claiming that men and women can choose God by their own ability, these views ultimately ground salvation in human moral capacity rather than God’s grace. Pelagianism was formally condemned as heretical at the Council of Carthage (AD 418) for denying original sin and the necessity of grace. Semi-Pelagianism was later rejected at the Second Council of Orange (AD 529), which affirmed that even the beginning of faith is the result of God’s gracious work rather than human initiative.

implications for today

Pelagianism teaches that human beings are born morally neutral and possess the natural ability to obey God and live righteously apart from divine grace. It arose in the late fourth and early fifth centuries through the teaching of Pelagius, a British monk who objected to what he saw as moral laxity among Christians. Pelagius denied that Adam’s sin resulted in moral corruption passed down to later generations, arguing instead that each person is created in the same moral state as Adam before the fall. In this view, grace may assist obedience, but it is not necessary for choosing good or attaining righteousness.

Semi-Pelagianism developed in the fifth century as an attempted compromise between Pelagianism and the church’s growing emphasis on divine grace. It acknowledged that Adam’s sin had a real adverse effect on humanity but maintained that fallen humans still retain the ability to take the first step toward God. According to this view, a person can initiate faith or respond positively to God without prior inward transformation, after which divine grace cooperates with human effort. This position became influential in parts of the Western church and was later rejected for continuing to ground salvation partly in human ability.

Scripture teaches that everyone is born dead in their sins. Dead people do not reach out on their own, and the spiritually dead are incapable of making themselves right with God. Indeed, the Bible teaches that, outside of God’s help, no one even wants to find Him. Instead, they suppress every bit of knowledge they have so that they can keep sinning. If it were not for God drawing some to Himself, no one would be saved. The reason that Pelagianism was condemned as heresy was that it contradicted Scripture, teaching that men and women could save themselves.

However, the fact that God must save people does not mean that His calls to repent and believe are less real. What it means is that God’s grace makes repentance possible. If you have never believed, know if you feel sorrow for your sin and desire forgiveness, that may be a sign that God is working to open your eyes and soften your heart. He may be drawing you to understand the gospel.

The gospel is simple. God sent His Son, Jesus Christ, into the world to live the life we could not live and to die the death our sins deserved. Jesus obeyed God perfectly, never sinning, and then willingly gave Himself on the cross, bearing God’s judgment in place of guilty people. He rose from the dead, proving that sin and death had been defeated.

Salvation does not come from trying harder or becoming better. It comes through repentance and faith. Repentance means turning from sin and admitting you need mercy. Faith means trusting that Jesus’ death and resurrection are enough to save you. God calls you to come to Christ as you are. Everyone who turns to Jesus in faith will be forgiven, made alive, and eternally saved.
