Existence of God
PROOFS AND EVIDENCES OF THE EXISTENCE OF GOD
One of the proofs and demonstrations of the existence of God is the fact that man did not create himself: nay, his creator and designer is another than himself.
It is certain and indisputable that the creator of man is not like man because a powerless creature cannot create another being. The maker, the creator, has to possess all perfections in order that he may create.
Can the creation be perfect and the creator imperfect? Can a picture be a masterpiece and the painter imperfect in his art? For it is his art and his creation. Moreover, the picture cannot be like the painter; otherwise, the painting would have created itself. However perfect the picture may be, in comparison with the painter it is in the utmost degree of imperfection.
The contingent world is the source of imperfections: God is the origin of perfections. The imperfections of the contingent world are in themselves a proof of the perfections of God.
