Abstract
This paper explores Augustine’s use of the twin images of Christ the physician and sin as sickness, especially in his sermons and Confessions. It shows how distinctive features of this image enable Augustine to illuminate a scriptural moral theology that is egalitarian and developmental. It is founded upon repentance, humility and a powerful awareness of dependence upon God’s grace, and demands communal responsibility for morality. Augustine’s moral theory fully integrates his personal and pastoral experience; the relevant similarities between his own society and ours suggest that his theory, in its broad outlines, has not lost its validity
