伯拉纠主义（Pelagianism）是由英国人伯拉纠提出的一种理论，这种理论认为人的本性是恶的。

伯拉纠(Pelagius, 390-418)提出的言论与斯多亚学派类似，承认人类本性是恶的，但可以借着受洗，因着信而得以称义，强调保罗因信称义的观念。在伯拉纠的门人中，以色勒斯丢最为显著拥护他的主张，他是一位执业律师，因此善于争辩，所以拥护伯拉纠的信徒也不少。此事经奥古斯丁了解后，开始一连串的争辩，因为此派的思想不承认人有原罪，又认为可以靠人自己的力量生活到无罪之境，此思想在东方广受欢迎，并且经耶路撒冷主教的承认，在丢司坡理开会宣布伯拉纠此派的思想合乎正道。

Pelagianism is the belief that original sin did not taint human nature and that mortal will is still capable of choosing good or evil without special Divine aid. This theological theory is named after the British monk Pelagius (354–420 or 440), although he denied, at least at some point in his life, many of the doctrines associated with his name. Pelagius taught that the human will, as created with its abilities by God, was sufficient to live a sinless life, although he believed that God's grace assisted every good work. Pelagianism has come to be identified with the view, (whether Pelagius agreed or not), that human beings can earn salvation by their own efforts.
