The operative word in Augustine’s view is that regenerating grace is monergistic. It is the work of God alone. Pelagius rejected the doctrine of monergistic grace and replaces it with a view of synergism, which involves a work of cooperation between God and man.

The early part of the fifth century witnessed a serious controversy in the church that is known as the Pelagian controversy. This debate took place principally between the British monk Pelagius and the great theologian of the first millennium, Augustine of Hippo. In the controversy, Pelagius objected strenuously to Augustine’s understanding of the fall, of grace, and of predestination. Pelagius maintained that the fall affected Adam alone and that there was no imputation of guilt or “original sin” to Adam’s progeny. Pelagius insisted that people born after the fall of Adam and Eve retained the capacity to live lives of perfect righteousness unaided by the grace of God. He argued that grace “facilitates” righteousness but is not necessary for it. He categorically rejected Augustine’s understanding that the fall was so severe that it left the descendents of Adam in such a state of moral corruption that they were morally unable to incline themselves to God. The doctrines of Pelagius were condemned by the church in 418 at a synod in Carthage.

Though Pelagianism was rejected by the church, efforts soon emerged to soften the doctrines of Augustine. In the fifth century the leading exponent of such a softening was John Cassian. Cassian, who was the abbot of a monastery in Gaul, together with his fellow monks, completely agreed with the condemnation of Pelagius by the synod in 418, but they objected equally to the strong view of predestination set forth by Augustine. Cassian believed that Augustine had gone too far in his reaction against the heresy of Pelagius and had departed from the teachings of some of the church fathers, especially Tertullian, Ambrose, and Jerome. Cassian said that Augustine’s teaching on predestination “cripples the force of preaching, reproof, and moral energy…plunges men into despair and introduces a certain fatal necessity.” This reaction against the implied fatalism of predestination led Cassian to articulate a position that has since become known popularly as “semi-Pelagianism.” Semi-Pelagianism, as the name implies, suggests a middle ground between Pelagius and Augustine. Though grace facilitates a life of righteousness, Pelagius thought it was not necessary. Cassian argues that grace not only facilitates righteousness, but it is an essential necessity for one to achieve righteousness. The grace that God makes available to people, however, can and is often rejected by them.
