My Theology:The world s leading Christian thinkers explain some of the principal tenets of their theological beliefs. In one lifetime, the world we expected to live in has all but disappeared. Belief is reasoned, not recited. The God that we were brought up on is not big enough to be God, writes Joan Chittister. To be both religious and spiritual, modernity must be able to absorb the notion of a cosmic and evolving God and society. Old ideas of who is in charge, who is superior and whose theology is paramount is in a state of flux.Despite this uncertain state of the world, Sr Joan finds that she believes more now than she ever really understood; a new idea of God is emerging which is greater than the sum of all we have been previously taught.
