God and his attributes:

God most normally refers to the holy being worshipped by followers of monotheistic and monolatrist religions, whom they accept as true to be the creator and ruler of the world.

Theologians have ascribed various attributes to a variety of conceptions of God. The most ordinary among these consist of omniscience, perfect goodness, omnipotence, omnipresence, divine simplicity, and everlasting and necessary existence. God has also been conceived as being incorporeal, a personal being, the source of the entire moral obligations, and the "greatest conceivable existent". These attributes were all supported to varying degrees by the early Christian, Jewish and Muslim theologian philosophers, including Augustine of Hippo, Al-Ghazali, and Maimonides. Many famous medieval philosophers developed arguments for the existence of God, attempting to fight with the obvious contradictions implied by many of these attributes.
