Ali Bonner in The Myth of Pelagianism argues that Augustine misrepresented Pelagius as a perfectionist who taught that good and evil were equally within human power. She claims Pelagius only taught that “human nature was inclined to goodness, and that man had free will.” She disputes Augustine’s teachings of “original sin,” what she calls “an absolutist account of prevenient grace,” and “predestination interpreted as preordainment” as the only orthodox positions in the church. This paper will explore the development of Augustine’s doctrine of grace and predestination, its biblical merit, and respond to Bonner’s contention that Augustine caricatured Pelagius in order to refute him more easily.
