 Panentheism continues to grow and change. Much of this growth has taken place as a result of advances in science and conversations with science. This growth has led to diverse forms of panentheism such as soteriological, revelational or expressivist, and dipolar (Gregersen 2004, 21). The variety of forms of panentheism has also resulted in different degrees of panentheism ranging from explicit fully developed panentheism to vague and underdeveloped forms of panentheism and to expressions of theism that share certain concepts with fully developed forms of panentheism. Michael Brierley lists three premises as distinctive to panentheism: God is not separate from the cosmos, God is affected by the cosmos, and God is more than the cosmos (2006, 639–640). Fully developed panentheism includes thinkers such as Charles Hartshorne, Phillip Clayton, Leonardo Boff, Peter Hodgson, John Macquarrie, Sallie McFague, Jürgen Moltmann, and Arthur Peacocke who have identified themselves as panentheists. Other thinkers such as Paul Tillich have rarely self-identified as panentheists but share concepts with panentheism (Burch 1998, 251). And finally, especially through world religions and early theologies various forms of theism offer diversity sharing certain concepts with panentheism.
