It should be emphasized, however, that for Whitehead God is not necessarily tied to religion. Rather than springing primarily from religious faith, Whitehead saw God as necessary for his metaphysical system. His system required that an order exist among possibilities, an order that allowed for novelty in the world and provided an aim to all entities. Whitehead posited that these ordered potentials exist in what he called the primordial nature of God. However, Whitehead was also interested in religious experience. This led him to reflect more intensively on what he saw as the second nature of God, the consequent nature. Whitehead's conception of God as a "dipolar" entity has called for fresh theological thinking.

Why did Whitehead view the existence of God as a necessity for his mathematical system?
