Modal panentheism claims that God encompasses all possible worlds and that a substantial number of possible worlds exist. This article defends a version of modal panentheism that is grounded in perfect-being theology, which maintains that God holds all great-making properties to the highest possible degree. In addition to goodness, modal panentheists consider encompassment to be a great-making property, and therefore, God (a maximally encompassing being) is said to encompass all possible worlds.

Nagasawa argues that modal panentheism faces a significant problem: the modal problem of evil. The argument states that if modal realism is true, then there exists a substantial number of possible evils that contradict God’s perfect goodness. Nagasawa proceeds to claim that modal evil poses a greater threat to modal panentheism than actual evil does to traditional theism.

This article develops two responses to the modal problem of evil. The first response (maximal-panentheism) argues that God need not be all-good or all-encompassing. The second response (no evil worlds) argues that worlds contradicting God’s perfect goodness are not possible worlds. In the light of these responses, I claim the modal problem of evil for modal panentheism is no more intractable than the problem of evil for traditional theism.

The fluctuating maximal God thesis, developed by Jeffrey et al., offers a conception of God that removes the characteristic of divine immutability, allowing the degrees of God's great-making properties to change over time. This god-concept provides a substantial advantage over the ‘static’ maximal God thesis proposed by Yujin Nagasawa if it can adequately sidestep what I call ‘the problem of inconsistent evil’. This problem questions how a static god can be compatible with the inconsistent dispersion of evil in the world. It is founded on the observation that evil is distributed neither equally nor fairly across time, space, and individuals. I distinguish between temporally inconsistent, spatially inconsistent, and interpersonally inconsistent evil and argue that the fluctuating maximal God thesis can account for all types of inconsistent evil if God fluctuates not only through time but also through space.
