ABSTRACT
This chapter proposes a compatibility of commonsense morality with Christian morality and to remove worries that might hold back one's support for commonsense morality. It then shows how the proposed compatibility can be conceptually articulated, overcoming potential philosophical and theological issues. The chapter introduces three models in order to make a conceptual distinction among some competing models of compatibility. The three models are: the identity model, the two-tier model, and the integration model. Preferring the integration model over the others, is best to understand commonsense morality as an integral part of Christian morality, the former, though not identical with the latter, remains a necessary and central part of the latter. The chapter then addresses remaining philosophical and theological issues concerning the proposed compatibility between the two moralities. Using the philosophical problem of supererogation, it highlights strengths of the integration model, while answering possible philosophical and theological objections to the model.
