Potamius of Lisbon

In order that the unity itself of the threefold majesty and imprint should encounter our understanding, the invisible majesty itself states so: “Let us make man in our image and according to our likeness.” Look! He has demonstrated what we believe. God has engraved his image on the face of the human and has said “in our image.” The knowledge of Father and Son is impressed upon the face of man; and the very features of his face, by means of the clay by which we are formed, revealed in the human original model how the Father and the Son were, so that man could admire God in man.
