What is the myth of pelagianism?

Pelagianism is a theological heresy that originated in the fifth century and was associated with the teachings of Pelagius, a British monk. Pelagianism claimed that human beings have the ability to choose good and avoid evil, without the need for God's grace. Pelagius believed that Adam's sin did not taint human nature and that humans retain the ability to choose sin or obedience.

However, Augustine of Hippo, one of the most influential Christian theologians of all time, vehemently opposed Pelagianism. Augustine taught that all human beings are born sinful and are incapable of choosing good without God's grace. He argued that Adam's sin had corrupted human nature and that salvation was only possible through faith in Jesus Christ.

The debate between Pelagianism and Augustinianism became a major issue in the early Christian Church, ultimately leading to the condemnation of Pelagianism as a heresy. Despite this, Pelagianism has continued to influence some theological thought throughout history, including in some aspects of modern liberal theology.
