From The Apology of Aristides:
I say, then, that God is not born, not made, an ever-abiding nature without beginning and without end, immortal, perfect, and incomprehensible. Now when I say that he is “perfect,” this means that there is not in him any defect, and he is not in need of anything but all things are in need of him. And when I say that he is “without beginning,” this means that everything which has beginning has also an end, and that which has an end may be brought to an end. He has no name, for everything which has a name is kindred to things created. Form he has none, nor yet any union of members; for whatsoever possesses these is kindred to things fashioned. He is neither male nor female. The heavens do not limit him, but the heavens and all things, visible and invisible, receive their bounds from him. Adversary he has none, for there exists not any stronger than he. Wrath and indignation he possesses not, for there is nothing which is able to stand against him. Ignorance and forgetfulness are not in his nature, for he is altogether wisdom and understanding; and in Him stands fast all that exists. He requires not sacrifice and libation, nor even one of things visible; He requires not aught from any, but all living creatures stand in need of him.
