From publisher blurb:
Divine Power at Your Command
Mastery of divine power is no longer reserved for the cleric or paladin. With devotion and dedication, any hero can become a divine champion and a force to shake the heavens. Your strength comes from the universe itself, and you can use your divine gifts to create, heal, or destroy. Your choices shape the world.
This book gives players and Dungeon Masters an unprecedented resource for using divine power and religion in their game. In addition to new feats, spells, items, and prestige classes, the Complete Champion game supplement presents exciting adventure locations, afilliation mechanics for different deities and organizations, and a system for designing your own religions based on the cleric domain system. Alternative class features for every standard class and more reserve feats provide extended options for players interested in creating or advancing characters along the road to divine power.
