Deuteronomy 13:4

Now Plato the philosopher, defining the end of happiness, says that it is likeness to God as far as possible; whether concurring with the precept of the law (for great natures that are free of passions somehow hit the mark respecting the truth, as the Pythagorean Philo says in relating the history of Moses), or whether instructed by certain oracles of the time, thirsting as he always was for instruction. For the law says, “Walk after the Lord your God, and keep my commandments.” For the law calls assimilation following; and such a following to the utmost of its power assimilates. “Be,” says the Lord, “merciful and pitiful, as your heavenly Father is pitiful.” Thence also the Stoics have laid down the doctrine, that living agreeably to nature is the end, fitly altering the name of God into nature; since also nature extends to plants, to seeds, to trees, and to stones. …

Wherefore also man is said “to have been made in [God’s] image and likeness.” For the image of God is the divine and royal Word, the impassible man; and the image of the image is the human mind. And if you wish to apprehend the likeness by another name, you will find it named in Moses, a divine correspondence. For he says, “Walk after the Lord your God, and keep His commandments.” And I reckon all the virtuous, servants and followers of God. Hence the Stoics say that the end of philosophy is to live agreeable to nature; and Plato, likeness to God, as we have shown in the second Miscellany. And Zeno the Stoic, borrowing from Plato, and he from the Barbarian philosophy, says that all the good are friends of one another. …

And we do not ask the question, “How shall we go to God?” as though we thought that God existed in some place. God is of too excellent a nature for any place: He holds all things in His power, and is Himself not confined by anything whatever. The precept, therefore, “Thou shalt walk after the Lord thy God,” does not command a bodily approach to God; neither does the prophet refer to physical nearness to God, when he says in his prayer, “My soul followeth hard after Thee.” Celsus therefore misrepresents us, when he says that we expect to see God with our bodily eyes, to hear Him with our ears, and to touch Him sensibly with our hands. …

5. From Deuteronomy; ‘But ye that did attach yourselves unto the Lord your God are alive every one of you this day.’ From this we may see the difference, and know that the Son of God is not a creature. For the Son says, ‘I and the Father are One,’ and, ‘I in the Father, and the Father in Me;’ but things originate, when they make advance, are attached unto the Lord. The Word then is in the Father as being His own; but things originate, being external, are attached, as being by nature foreign, and attached by free choice. For a son which is by nature, is one with him who begat him; but he who is from without, and is made a son, will be attached to the family. …
