Genesis 5:1

1.This is the book of the generations of Adam. In this chapter Moses briefly recites the length of time which had intervened between the creation of the world and the deluge; and also slightly touches on some portion of the history of that period. And although we do not comprehend the design of the Spirit, in leaving unrecorded great and memorable events, it is, nevertheless, our business to reflect on many things which are passed over in silence. I entirely disapprove of those speculations which every one frames for himself from light conjectures; nor will I furnish readers with the occasion of indulging themselves in this respect; yet it may, in some degree, be gathered from a naked and apparently dry narration, what was the state of those times, as we shall see in the proper places. The book, according to the Hebrew phrase, is taken for a catalogue. The generations signify a continuous succession of a race, or a continuous progeny. Further, the design with which this catalogue was made, was, to inform us, that in the great, or rather, we might say, prodigious multitude of men, there was always a number, though small, who worshipped God; and that this number was wonderfully preserved by celestial guardianship, lest the name of God should be entirely obliterated, and the seed of the Church should fail.

In the day that God created. He does not restrict these “generations” to the day of the creation, but only points out their commencement; and, at the same time, he distinguishes between our first parents and the rest of mankind, because God had brought them into life by a singular method, whereas others had sprung from a previous stock, and had been born of parents. (253) Moreover, Moses again repeats what he had before stated that Adam was formed according to the image of God, because the excellency and dignity of this favor could not be sufficiently celebrated. It was already a great thing, that the principal place among the creatures was given to man; but it is a nobility far more exalted, that he should bear resemblance to his Creator, as a son does to his father. It was not indeed possible for God to act more liberally towards man, than by impressing his own glory upon him, thus making him, as it were, a living image of the Divine wisdom and justice. This also is of force in repelling the calumnies of the wicked who would gladly transfer the blame of their wickedness to their Maker, had it not been expressly declared, that man was formed by nature a different being from that which he has now become, through the fault of his own defection from God.
