And God said,
Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creeps upon the earth.
All Commentaries on Genesis 1:26 Go To Genesis 1
Augustine of Hippo
AD 430
For why the “our,” if the Son is the image of the Father alone? But it is on account of the imperfect likeness, as we have said, that man is spoken of as “after our image,” and so “our,” that man might be an image of the Trinity. This image is not equal to the Trinity, as the Son is to the Father, but approaching it, as is said, by a certain likeness; as in things distinct there can be closeness, not however in this case as if a spatial closeness but by imitation. .
