The prevailing view of Christian philosophers today seems to be that Christianity requires a libertarian conception of free will. Focusing on Augustine’s mature anti-Pelagian works, I try to show that the prevailing view is in error. Specifically, I want to show that---on Augustine’s view of grace-a libertarian account of free will is irrelevant to salvation. On Augustine’s view, the grace of God through Christ is sufficient as weIl as necessary for salvation. Salvation is entirely in the hands of God, totally independent of anything that any human being might do. And faith, the human response to salvation, is best understood in terms of a compatibilist account of freedom.

In his reflections on his adolescent theft of a neighbor’s pears, Augustine first claims that he did it just because it was wicked. But he then worries that there is something unacceptable in that claim. Some readers have found in this account Augustine’s rejection of the principle that all voluntary action is done for the sake of some perceived good. I argue that Augustine intends his case to call the principle into question, but that he does not ultimately reject it. His careful and resourceful analysis of the motivations of his theft adds subtlety to his own understanding of voluntary action and allows hirn to introduce an important component of his general account of sin, namely, that it essentially involves prideful self-assertion in imitation of God.
