Genesis

Genesis is the book of beginnings — of the cosmos, of humanity, of sin, and of the long covenantal arc that culminates in Christ. The Hebrew title, Bereshit (“In the beginning”), is taken from its first word; the Greek Septuagint and the Latin Vulgate render it Genesis (“origin”). It opens the Pentateuch, the five books of Moses, and supplies the foundation upon which the rest of Scripture stands.

Catholic tradition has long ascribed Genesis to Moses, an ascription affirmed by the Pontifical Biblical Commission in its 1906 decree on Mosaic authorship. Modern Catholic exegesis recognizes that Moses likely drew on earlier oral and written traditions, and that subsequent inspired editors completed and arranged the text — yet the substantial Mosaic origin of the Pentateuch remains the Church's traditional teaching. The events of the patriarchs are typically dated to the early second millennium BC, with the book reaching its final form during the period of the wilderness wanderings or shortly thereafter.

The major themes of Genesis are creation, covenant, and promise. The opening chapters present a God who speaks the universe into being, who makes humanity in his own image, and who responds to disobedience not with annihilation but with the protoevangelium — the first promise of a Redeemer who will crush the serpent's head (Gen. 3:15). The remainder of the book traces the unfolding of that promise through Noah, Abraham, Isaac, Jacob, and Joseph — chosen instruments through whom God preserves a people for himself.

Literarily, Genesis falls into two great movements. Chapters 1–11 are the primeval history: creation, the Fall, Cain and Abel, the Flood, the Tower of Babel — universal in scope, addressing the human condition as such. Chapters 12–50 are the patriarchal history: Abraham's call, the binding of Isaac, Jacob's wrestling with God, Joseph's exile and exaltation in Egypt — particular and familial, narrowing the focus to the chosen line.

In Catholic liturgy, Genesis is the heart of the Easter Vigil's Old Testament readings: creation, the binding of Isaac, the crossing of the Red Sea (read with Exodus). The Catechism draws on Genesis to teach about the dignity of the human person (CCC 355), original sin (CCC 396–409), and the meaning of marriage (CCC 1602–1605). Genesis is, in a real sense, the seedbed of the entire economy of salvation — every later book of Scripture grows from soil it first turned.
