Charles Ellicott Commentary Luke 3:38

"the [son] of Enos, the [son] of Seth, the [son] of Adam, the [son] of God." — Luke 3:38 (ASV)

Which was the son of God.—The whole form of the genealogy leads us to apply these words to Adam.

Humanity as such, as the result of an immediate creative act, was the offspring of God (Acts 17:28). And the words of the angel (Luke 1:35) imply that because the human nature of our Lord originated in a similar creative act, it was entitled—no less than by its union with the Sonship of the Eternal Word—to be called the Son of God. What was true of the second Adam was also true partly, though in a different measure, of the first.
