6 Seeing then that many have gone astray in various ways from the One God, some having deified the sun, that when the sun sets they may abide in the night season without God; others the moon, to have no God by day; others the other parts of the world; others the arts; others their various kinds of food; others their pleasures; while some, mad after women, have set up on high an image of a naked woman, and called it Aphrodite, and worshipped their own lust in a visible form; and others dazzled by the brightness of gold have deified it and the other kinds of matter;— whereas if one lay as a first foundation in his heart the doctrine of the unity of God, and trust to Him, he roots out at once the whole crop of the evils of idolatry, and of the error of the heretics: lay thou, therefore, this first doctrine of religion as a foundation in your soul by faith.
Of Christ.
