Composition Date Of Genesis
Traditional Christian scholarship has long attributed Genesis to Moses, with composition occurring during Israel's wilderness wanderings between approximately 1491 and 1451 BC [1]. This dating places the writing roughly a millennium and a half after the patriarchal narratives and more than two millennia after the creation account itself, positioning Genesis as a retrospective record of events preserved through oral tradition and divine revelation.
Smith's Bible Dictionary specifies that the book covers 2,369 years of history, from Adam's creation to Joseph's death around 1635 BC [1]. The forty-year wilderness period provided Moses with both the time and the theological context to compile Israel's foundational narrative. During this formative era, the nation needed an account explaining their origins, their covenant relationship with Yahweh, and their claim to Canaan—precisely what Genesis delivers through its carefully structured genealogies and covenant narratives.
The Mosaic Authorship Framework
The traditional view treats Genesis as the opening volume of the Pentateuch, which Jews called the Torah and Greeks termed the "five-fold book" [3]. The name "Genesis" itself derives from the Septuagint translation, meaning "origin" or "creation," while Hebrew manuscripts begin with Bereshith ("in the beginning"), the book's opening word [1, 3]. This dual naming convention reflects the text's transmission through both Jewish and Hellenistic channels.
Calvin's extensive commentary on Genesis, spanning both volumes of his exposition, demonstrates how Reformation scholars engaged the text as Mosaic without questioning its mid-second-millennium BC composition [4, 5, 6, 7]. The reformers treated the genealogical markers in Genesis 5:1 and throughout the text as authentic historical records [2], connecting the patriarchs to Moses's own era through unbroken lineage.
The wilderness setting explains Genesis's theological emphases: the establishment of monotheism against Egyptian polytheism, the covenant promises justifying Israel's territorial claims, and the patriarchal narratives establishing tribal identities. These concerns align precisely with a community poised to enter Canaan after Egyptian bondage, making the traditional dating internally coherent with the text's apparent purposes.

- Easton's Bible Dictionary “Easton's Bible Dictionary: Genesis — The five books of Moses were collectively called the Pentateuch, a word of Greek origin meaning "the five-fold book." The Jews called them the Torah, i.e., "the law." It is probable that the division of the Torah into five books proceeded from the Greek translators of the Old Testament. The names by which these several books are generally known are Greek. The first book of the Pentateuch (q.v.) is called by the Jews Bereshith, i.e., "in the beginning", because this is the first word of the book. It is generally known among Christians by the name of Genesis,”
