This text offers consistent and compatible definitions of omnipotence, omniscience and omnibenevolence. Variant greater-good defences are explored and derivations of a basic account of this defence are traced to theistic tenets. It also gives accounts of the origins of evil. The free-will defence, soul-making defence and an original redemption defence are viewed as specifications of the more general greater-good defence. It is argued that the defences can be assembled into a complementary apologetic complex that defeats the charge that God's existence is incompatible with evil's existence.
