Abstract
Can God be entirely and supremely just and also entirely merciful, without these two characteristics ending up in contradiction with each other? Anselm of Canterbury considers this question in several places in his works and provides rational resolutions demonstrating the compatibility of divine justice and mercy. This paper considers Anselm's treatment of the problem in the Cur Deus Homo, noting distinctive features of his account, highlighting the seeming incompatibilities between mercy and justice, and setting out his resolution of the problem.
