4 Some of these teachers brought forward large households of dubious deities, and under the persuasion that there is a sexual activity in divine beings narrated births and lineages from god to god. Others asserted that there were gods greater and less, of distinction proportionate to their power. Some denied the existence of any gods whatever, and confined their reverence to a nature which, in their opinion, owes its being to chance-led vibrations and collisions. On the other hand, many followed the common belief in asserting the existence of a God, but proclaimed Him heedless and indifferent to the affairs of men.
Again, some worshipped in the elements of earth and air the actual bodily and visible forms of created things; and, finally, some made their gods dwell within images of men or of beasts, tame or wild, of birds or of snakes, and confined the Lord of the universe and Father of infinity within these narrow prisons of metal or stone or wood. These, I was sure, could be no exponents of truth, for though they were at one in the absurdity, the foulness, the impiety of their observances, they were at variance concerning the essential articles of their senseless belief.
My soul was distracted amid all these claims, yet still it pressed along that profitable road which leads inevitably to the true knowledge of God. It could not hold that neglect of a world created by Himself was worthily to be attributed to God, or that deities endowed with sex, and lines of begetters and begotten, were compatible with the pure and mighty nature of the Godhead. Nay, rather, it was sure that that which is Divine and eternal must be one without distinction of sex, for that which is self-existent cannot have left outside itself anything superior to itself.
Hence omnipotence and eternity are the possession of One only, for omnipotence is incapable of degrees of strength or weakness, and eternity of priority or succession. In God we must worship absolute eternity and absolute power.
