17. Let us see then, if haply we cannot find something in the creature whereby we may prove that some three things are exhibited separately whose operation is yet inseparable. But whither shall we go? To the heaven, to dispute of the sun and moon and stars? To the earth, to dispute of shrubs, and trees, and animals which fill the earth? Or of the heaven and the earth itself, which contain all the things that are in heaven and earth? How long, O man, wilt thou roam over the creation? Return unto thyself, see, consider, examine thine own self. Thou art searching among the creatures for some three things which are separately exhibited, whose operation is yet inseparable; if then thou art searching for this among the creatures, search for it first in thine own self. For thou art not other than a creature. It is a resemblance thou art searching for. Wouldest thou search for it among the cattle? For of God it was thou wast speaking, when thou wast in search for this resemblance. Thou wast speaking of the Trinity of Majesty ineffable, and because thou didst fail in contemplating the Divine Nature, and with becoming humility didst confess thine infirmity, thou didst come down to human nature; there then pursue thine enquiry. Wilt thou make thy search among the cattle, in the sun, or the stars? What of these was made after the image and likeness of God? Thou mayest search in thine own self for something more familiar to thee, and more excellent than all these. For God made man after His own image and likeness. Search then in thine own self, if haply the image of the Trinity bear not some vestige of the Trinity. And what is this image? It is an image very different from its model; yet different as it is, it is an image and a likeness notwithstanding, not indeed in the same way as the Son is the Image, being the Same Which the Father is. For an image is in one sort in a son, and in another in a mirror. There is great difference between them. Thine image in thy son is thine own self, for the son is by nature what thou art. In substance the same as thou, in person other than thou. Man then is not an image as the Only-begotten Son is, but made after a sort of image and likeness. Let him then search for something in himself, if so be he may find it, even for some three things which are exhibited separately, whose operation is yet inseparable. I will search, and do ye search with me. I will not search in you, but do ye search in yourselves, and I in myself. Let us search in concert, and in concert discuss our common nature and substance.
