This thesis is an explorative study to compare Augustine and Wesley s concepts of prevenient grace, in order to find out their similarities and differences. The study reveals 16 similarities and 11 differences between Augustine and Wesley s concepts of prevenient grace. From these findings, this thesis further infers that some kinds of relationships exist between Augustine and Wesley s concepts of prevenient grace. Since the similarities outnumber the differences and relationships possibly exist between Augustine and Wesley s concepts of prevenient grace, this thesis further suggests that instead of labelling Wesley s concept of prevenient grace as semi-Pelagian, it is perhaps justifiable to call it semi-Augustinian. Finally, this study invites readers to further examine the suggested possible relationships between Augustine and Wesley s concepts of prevenient grace, to study relationships between their other theological concepts, and even to construct an Augustinian-Wesley legacy
