Thomas Aquinas essentially defines omnipotence as the power to do all that is logically possible. Other theologians have similarly defined omniscience as the ability to know all that it is possible to know. In his interesting study on evil and providence, Peter Geach suggests that God is not omnipotent but rather "almighty." Emil Brunner also develops this concept in The Christian Doctrine of God (volume I, page 248ff).
Brunner contends: "The Biblical conception [of God's almightiness] means God's power over the whole universe; but omnipotentia means the abstract idea that 'God can do everything.'" See Brunner, p. 248.
This distinction seems theologically meaningful or substantial. What are your thoughts on this matter?
