Panentheism articulates a metaphysical position wherein God includes and pervades the universe while simultaneously transcending it. This view posits that the cosmos exists within God as a proper part, yet God's being exceeds the totality of creation. Unlike pantheism which identifies God with the universe, panentheism maintains a real distinction between divine and created being while affirming their intimate ontological connection. The formulation typically employs the analogy of the world as God's body or the universe as existing "in" God, suggesting that finite entities participate in divine being without exhausting it.
The modern articulation of panentheism emerged through Karl Christian Friedrich Krause's "Vorlesungen über das System der Philosophie" (1828), though antecedents appear in Neoplatonic thought, particularly in Plotinus's concept of emanation and Ibn Arabi's wahdat al-wujud. Charles Hartshorne systematized process panentheism in "The Divine Relativity" (1948), arguing that God includes the world as a changing aspect of divine being. Philip Clayton's "God and Contemporary Science" (1997) developed emergentist panentheism, while Arthur Peacocke's "Theology for a Scientific Age" (1990) advanced a naturalistic version. Contemporary defenders include John Polkinghorne in "Science and the Trinity" (2004) and Paulos Gregorios in "The Human Presence" (1978), representing scientific and Eastern Orthodox perspectives respectively.
Classical theists object that panentheism compromises divine simplicity and aseity by making God dependent on creation for completeness. Brian Davies in "The Reality of God and the Problem of Evil" (2006) argues that if the world is part of God, then evil becomes a divine attribute. Panentheists respond that divine perfection need not entail static completeness but can include dynamic responsiveness to creation. Scientific naturalists critique panentheism as an unnecessary metaphysical addition to naturalistic explanations, while process panentheists counter that it better accounts for emergence, consciousness, and value than reductive materialism. The problem of divine action remains contentious: how can God act specially within a world that is already part of God's being?
Panentheism differs from classical theism by affirming real divine-world relations and rejecting strong divine simplicity. Unlike deism's absent God, the panentheistic God remains intimately involved with creation. Against open theism's temporal God with limited foreknowledge, most panentheists maintain divine eternality while affirming genuine divine responsiveness. Process theism represents one species of panentheism emphasizing divine becoming, while panentheism broadly includes positions maintaining divine immutability.
