The closing run of Luke's genealogy — Seth, Enosh, Cainan, Mahalalel, Jared, Enoch, Methuselah, Lamech, Noah, Shem, Arphaxad, and back to "the son of Seth, the son of Adam, the son of God" — is drawn directly from the antediluvian register of Genesis 5:1-3 (with Genesis 11:10-26 supplying the later names). Genesis 5 opens, "This is the book of the generations of Adam. In the day that God created man, He made him in His own likeness… When Adam was 130 years old, he had a son in his own likeness, after his own image; and he named him Seth" (5:1-3). Luke reproduces that line — following the Septuagint register, which is why the second Cainan appears at 3:36 — and runs it back not merely to Abraham but to Adam himself. The terminus is doing deliberate theological work: Luke has just recorded the Father's voice at the Jordan, "You are My beloved Son" (3:22), and immediately follows the genealogy with the wilderness temptation, where the devil twice presses, "If You are the Son of God" (4:3, 9). By tracing the line past Abraham to "the son of Adam, the son of God," Luke sets Jesus in solidarity with the whole human race and stations Him as the second Adam precisely where the first Adam, made in God's image and passing that marred image to Seth, had failed. The image lost in Adam is restored and surpassed in Christ, the true Son of God, in whom the human family finds its head.
