Theism
In the Philosophy of religion, Theism is the belief in God as unitary being. There are four major views of the role of God in the world in this context: proper Theism is the view that God is immanent in the world, yet transcends it; Deism is the view that God created the world but does not interact with it; Pantheism is the the view that the world is identical to God; and Panentheism is the view that the world entirely contained within God, while at the same time God is something greater than just the world.
The monotheistic religions, such as Judaism, Christianity, and Islam, are typically theistic.
More generically, theism can be described as the belief in one or more gods.
