Ross Cameron has argued that the modal realism of David Lewis furnishes the theist with the resources to explain divine necessity. Cameron is successful in identifying two theistic strategies, but neither is attractive in light of a commitment to modal realism. The first theistic strategy is to treat God as an abstract entity in the same way that the modal realist treats pure sets. This is undermotivated in light of the nominalistic spirit of modal realism. The second strategy is to regard God as enjoying trans-world identity because the divine nature can possess no accidental intrinsic properties. This approach raises a problem of how one is to understand the notion of actuality.
