De Principiis

³⁷ If any one, indeed, venture to ascribe essential corruption to Him who was made after the image and likeness of God, then, in my opinion, this impious charge extends even to the Son of God Himself, for He is called in Scripture the image of God. Or he who holds this opinion would certainly impugn the authority of Scripture, which says that man was made in the image of God; and in him are manifestly to be discovered traces of the divine image, not by any appearance of the bodily frame, which is corruptible, but by mental wisdom, by justice, moderation, virtue, wisdom, discipline; in fine, by the whole band of virtues, which are innate in the essence of God, and which may enter into man by diligence and imitation of God; as the Lord also intimates in the Gospel, when He says, “Be therefore merciful, as your Father also is merciful;” and, “Be perfect, even as your Father also is perfect.” From which it is clearly shown that all these virtues are perpetually in God, and that they can never approach to or depart from Him, whereas by men they are acquired only slowly, and one by one.

And hence also by these means they seem to have a kind of relationship with God; and since God knows all things, and none of things intellectual in themselves can elude His notice (for God the Father alone, and His only-begotten Son, and the Holy Spirit, not only possess a knowledge of those things which they have created, but also of themselves), a rational understanding also, advancing from small things to great, and from things visible to things invisible, may attain to a more perfect knowledge.

For it is placed in the body, and advances from sensible things themselves, which are corporeal, to things that are intellectual. But lest our statement that things intellectual are not cognisable by the senses should appear unbecoming, we shall employ the instance of Solomon, who says, “You will find also a divine sense;” by which he shows that those things which are intellectual are to be sought out not by means of a bodily sense, but by a certain other which he calls “divine.”

And with this sense must we look on each of those rational beings which we have enumerated above; and with this sense are to be understood those words which we speak, and those statements to be weighed which we commit to writing. For the divine nature knows even those thoughts which we revolve within us in silence. And on those matters of which we have spoken, or on the others which follow from them, according to the rule above laid down, are our opinions to be formed.
