From the Greek pan - 'all' en - 'in' theos - 'god', literally "all is in God."

In the Philosophy of Religion, this definition of God asserts that all the universe is an expression or extension of the divine nature, but that God is not simply equal to the sum of the parts of the Universe as is maintained in Pantheism. God is the "ground of all being" which both superceeds and exceeds the universe. Everything is in God, but God is greater than the sum of the parts.

This view was popularized by the German theologian Paul Tillich.
