10 God then being thus great, and yet greater, (for even were I to change my whole substance into tongue, I could not speak His excellence: nay more, not even if all Angels should assemble, could they ever speak His worth), God being therefore so great in goodness and majesty, man has yet dared to say to a stone that he has graven, You are my God! O monstrous blindness, that from majesty so great came down so low! The tree which was planted by God, and nourished by the rain, and afterwards burnt and turned into ashes by the fire—this is addressed as God, and the true God is despised.
But the wickedness of idolatry grew yet more prodigal, and cat, and dog, and wolf were worshipped instead of God: the man-eating lion also was worshipped instead of God, the most loving friend of man. The snake and the serpent, counterfeit of him who thrust us out of Paradise, were worshipped, and He who planted Paradise was despised. And I am ashamed to say, and yet do say it, even onions were worshipped among some. Wine was given to make glad the heart of man: and Dionysus (Bacchus) was worshipped instead of God.
God made grain by saying, Let the earth bring forth grass, yielding seed after his kind and after his likeness, that bread may strengthen man's heart: why then was Demeter (Ceres) worshipped? Fire comes forth from striking stones together even to this day: how then was Hephæstus (Vulcan) the creator of fire?
