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 God said, “Let us make man in our image and likeness”: a little later, however, it is said “And God made man in the image of God.” It would certainly not be correct to say “our,” because the number is plural, if man were made in the image of one person, whether Father, Son or Holy Spirit. But because he is made in the image of the Trinity, consequently it was said “in our image.” Again, lest we choose to believe in three gods in the Trinity, since the same Trinity is one God, he said, “And God made man in his image,” as if he were to say “in his [own triune] image.” .
