I’ve found some corroboration on how to read Genesis 5:3, a verse that has been perplexing me for the last year and a half: “When Adam had lived 130 years, he fathered a son in his own likeness, after his image, and named him Seth.”

Stephen Dempster, Dominion and Dynasty, 58: “by juxtaposing the divine creation of Adam in the image of God and the subsequent human creation of Seth in the image of Adam, the transmission of the image of God through this genealogical line is implied, as well as the link between sonship and the image of God. As Seth is a son of Adam, so Adam is a son of God.”
