Process theology or process thought is a school of thought which represents a development from a Hegelian view, together with new insights derived from mathematical physics. Its originator is Alfred North Whitehead (1861–1947) with his metaphysical process philosophy, further developed by Charles Hartshorne (1897–2000). While there are process theologies that are similar, but unrelated to the work of Whitehead (such as Pierre Teilhard de Chardin) the term is generally applied to the Whiteheadian/Hartshornean school. For both Whitehead and Hartshorne, it is an essential attribute of God to be fully involved in and affected by temporal processes, an idea that conflicts with traditional forms of theism that hold God to be in all respects non-temporal (eternal), unchanging (immutable), and unaffected by the world (impassible). Process theology does not deny that God is in some respects eternal, immutable, and impassible, but it contradicts the classical view by insisting that God is in some respects temporal, mutable, and passible. Process theology is unrelated to the Process Church.
Process theology is an internally diverse field and while there are general directions that they all take, there are many ongoing debates such as on the nature of God, the relationship of God and the world, immortality, and interreligious dialogue.
Process theology may refer to all forms of theology that emphasise event, occurrence, or becoming over substance. In this sense theology influenced by Hegel is process theology just as much as that influenced by Alfred North Whitehead. Various theological and philosophical aspects have been expanded and developed by Charles Hartshorne (1897–2000), John B. Cobb, Jr., and David Ray Griffin. A characteristic of process theology each of these thinkers shared was a rejection of metaphysics that privilege "being" over "becoming", particularly those of Aristotle and Thomas Aquinas. Hartshorne was deeply influenced by French philosopher Jules Lequier and by Swiss philosopher Charles Secrétan who were probably the first ones to claim that in God liberty of becoming is above his substantiality.
Process theology soon influenced a number of Jewish theologians including Rabbis Max Kadushin, Milton Steinberg and Levi A. Olan, Harry Slominsky and, to a lesser degree, Abraham Joshua Heschel. Today some rabbis who advocate some form of process theology include Bradley Shavit Artson, Lawrence A. Englander, William E. Kaufman, Harold Kushner, Anton Laytner, Michael Lerner, Gilbert S. Rosenthal, Lawrence Troster, Donald B. Rossoff, Burton Mindick, and Nahum Ward.
The work of Richard Stadelmann has been to preserve the uniqueness of Jesus in process theology.
God and the World Relationship 
Whitehead's classical statement is a set of antithetical statements that attempt to avoid self-contradiction by shifting them from a set of oppositions into a contrast:
- It is as true to say that God is permanent and the World fluent, as that the World is permanent and God is fluent.
- It is as true to say that God is one and the World many, as that the World is one and God many.
- It is as true to say that, in comparison with the World, God is actual eminently, as that, in comparison with God, the World is actual eminently.
- It is as true to say that the World is immanent in God, as that God is immanent in the World.
- It is as true to say that God transcends the World, as that the World transcends God.
- It is as true to say that God creates the World, as that the World creates God.
Process Theism's Themes 
- God is not omnipotent in the sense of being coercive. The divine has a power of persuasion rather than coercion. Process theologians interpret the classical doctrine of omnipotence as involving force, and suggest instead a forbearance in divine power. "Persuasion" in the causal sense means that God does not exert unilateral control.
- Reality is not made up of material substances that endure through time, but serially-ordered events, which are experiential in nature. These events have both a physical and mental aspect. All experience (male, female, atomic, and botanical) is important and contributes to the ongoing and interrelated process of reality.
- The universe is characterized by process and change carried out by the agents of free will. Self-determination characterizes everything in the universe, not just human beings. God cannot totally control any series of events or any individual, but God influences the creaturely exercise of this universal free will by offering possibilities. To say it another way, God has a will in everything, but not everything that occurs is God's will.
- God contains the universe but is not identical with it (panentheism, not pantheism or pandeism). Some also call this "theocosmocentrism" to emphasize that God has always been related to some world or another.
- Because God interacts with the changing universe, God is changeable (that is to say, God is affected by the actions that take place in the universe) over the course of time. However, the abstract elements of God (goodness, wisdom, etc.) remain eternally solid.
- Charles Hartshorne believes that people do not experience subjective (or personal) immortality, but they do have objective immortality because their experiences live on forever in God, who contains all that was. Other process theologians believe that people do have subjective experience after bodily death.
- Dipolar theism, is the idea that God has both a changing aspect (God's existence as a Living God) and an unchanging aspect (God's eternal essence).
Relationship to liberation theology 
Henry Young combines Black theology and Process theology in his book Hope in Process. Young seeks a model for American society that goes beyond the alternatives of integration of Blacks into white society and Black separateness. He finds useful the process model of the many becoming one. Here the one is a new reality that emerges out of the discrete contributions of the many, not the assimilation of the many to an already established one.
Monica Coleman has combined Womanist theology and Process theology in her book Making a Way Out of No Way. In it, she argues that 'making a way out of no way' and 'creative transformation' are complementary insights from the respective theological traditions. She is one of many theologians who identify both as a process theologian and feminist/womanist/ecofeminist theologian, which includes persons such as Sallie McFague, Rosemary Radford Ruether, and Marjorie Hewitt Suchocki.
- There is a relational character to the divine which allows God to experience both the joy and suffering of humanity. God suffers just as those who experience oppression and God seeks to actualize all positive and beautiful potentials. God must, therefore, be in solidarity with the oppressed and must also work for their liberation.
- God is not omnipotent in the classical sense and so God does not provide support for the status quo, but rather seeks the actualization of greater good.
- God exercises relational power and not unilateral control. In this way God cannot instantly end evil and oppression in the world. God works in relational ways to help guide persons to liberation.
Relationship to pluralism 
Process theology affirms that God is working in all persons to actualize potentialities. In that sense each religious manifestation is the Divine working in a unique way to bring out the beautiful and the good. Additionally, scripture and religion represent human interpretations of the divine. In this sense pluralism is the expression of the diversity of cultural backgrounds and assumptions that people use to approach the Divine.
Relationship to the doctrine of the incarnation 
The Christ of process theology does not represent a hypostasis of divine and human personae. Rather God is incarnate in the lives of all humans when they act according to a call from God. Jesus fully and in every way responded to the call of God and so the person of Jesus is theologically understood to be “the divine Word in human form.” Jesus was not God-man in essence, but fully identified with God at all moments of life.
