Pelagianism is a theological doctrine associated with the teachings of Pelagius, a British monk who lived in the late 4th and early 5th centuries. While Pelagianism is not explicitly mentioned in the Bible, it relates closely to discussions about human nature, sin, and grace found in Scripture. The core tenet of Pelagianism is the belief that humans are capable of choosing good without the necessity of divine grace, implying that free will is sufficient for salvation. This view stands in contrast to traditional Christian teachings that emphasize the need for God's grace due to the fallen nature of humanity, a concept supported by texts such as Romans 3:23 ("For all have sinned and fall short of the glory of God") and Ephesians 2:8-9, which highlights salvation as a gift from God, not a result of human works.The early church, particularly through figures like Augustine of Hippo, opposed Pelagianism, arguing that it undermined the significance of original sin and the necessity of grace for salvation. Augustine's theology, reflected in passages like Romans 5:12-19, underscores that sin entered the world through one man (Adam) and that all humanity is affected by this original sin, thus requiring grace for redemption. Consequently, Pelagianism has been labeled a heresy in many Christian traditions, as it challenges the foundational beliefs about sin, grace, and the role of Christ in salvation as articulated throughout the New Testament.
