Mosaic authorship

Moses by José de Ribera (1638)

Mosaic authorship is the traditional Judeo-Christian belief that the Torah, the first five books of the Hebrew Bible/Old Testament, were dictated to Moses by the Abrahamic God.[1] The books do not name any author, as authorship was not considered important by the society that produced them,[2][3] and it was only after Jews came into intense contact with author-centric Hellenistic culture in the late Second Temple period that the rabbis began to find authors for their scriptures.[2] The tradition that Moses was this author probably began with the legalistic code of the Book of Deuteronomy and was then gradually extended until Moses, as the central character, came to be regarded not just as the mediator of law but as author of both laws and narrative.[4][5]

By the 1st century CE it was already common practice to refer to the five books as the "Law of Moses", but the first unequivocal expression of the idea that this meant authorship appears in the Babylonian Talmud, an encyclopedia of Jewish tradition and scholarship composed between 200 and 500 CE.[6][7] There the rabbis noticed and addressed such issues as how Moses had received the divine revelation,[8] how it was curated and transmitted to later generations, and how difficult passages such as the last verses of Deuteronomy, which describe his death, were to be explained.[9] This culminated in the 8th of Maimonides' 13 Principles of Faith, establishing belief in Mosaic authorship as an article of Jewish belief.[10]

Mosaic authorship of the Torah was unquestioned by both Jews and Christians until the European Enlightenment, when the systematic study of the five books led the majority of scholars to conclude that they are the product of multiple authors throughout many centuries.[11][12] Despite this, the role of Moses is an article of faith in Orthodox Jewish circles and for some Christian Evangelical scholars, for whom it remains crucial to their understanding of the unity and authority of the Bible.[13]


Many scholars see the biblical Moses as a mythical figure, while retaining the possibility that a Moses-like figure existed.[14][15][16][17] Whomever Moses was, scholars today agree almost unanimously that the Torah is the work of many authors over many centuries.[12] Even among evangelical scholars, the Mosaic authorship is endorsed only by the most conservative.[18] Jewish scholars such as Shaye J. D. Cohen and Richard Elliott Friedman also reject the Mosaic authorship.[19][20] Friedman declared "At present, however, there is hardly a biblical scholar in the world actively working on the problem who would claim that the Five Books of Moses were written by Moses — or by any one person."[20][21] Cohen stated about the battle of modern Bible scholars against traditional views of authorship of the Torah: "The great battleground is the Torah (the Pentateuch, the five books of Moses): is the Torah the earliest biblical book, revealed by God to Moses shortly after the Exodus, around 1300-1200 BCE, or one of the latest, not completed until the exilic period – or later? (see Kugel)".[19]

Development of the tradition

The Torah (or Pentateuch, as biblical scholars sometimes call it) is the collective name for the first five books of the Bible: Genesis, Exodus, Leviticus, Numbers, and Deuteronomy.[22][Notes 1] It forms the charter myth of Israel, the story of the people's origins and the foundations of their culture and institutions,[23] and it is a fundamental principle of Judaism that the relationship between God and his chosen people was set out on Mount Sinai through the Torah.[24]

The development of the Torah began by around 600 BCE, when previously unconnected material began to be drawn together; this happened while Judah was under the control of the Achaemenid Empire. By around 400 BCE these books, the forerunners of the Torah, had reached their modern form and began to be recognised as complete, unchangeable, and sacred. By around 200 BCE, while Israel and Judah part of the Seleucid Empire, the five books were accepted as the first section of the Jewish canon.[25][Notes 2] It seems that the tradition of Mosaic authorship was first applied to Deuteronomy,[5] which scholars generally agree was composed in Jerusalem during the reform program of King Josiah in the late 7th century BCE;[26] it is this law-code that books such as Joshua and Kings (completed in the mid-6th century BCE[27]) mean when they speak of the "torah of Moses."[5] In later books such as Chronicles and Ezra–Nehemiah the meaning had expanded to include the other laws such as Leviticus, and by the Hellenistic period, Jewish writers referred to the entirety of the five books, narrative and laws, as the Book (or books) of Moses.[5]

Authorship was not considered important by the society that produced the Hebrew Bible (the Christian Old Testament), and the Torah never names an author.[2][3] It was only after c. 300 BCE, when Jews came into intense contact with author-centric Greek culture, that the rabbis began to feel compelled to find authors for their books,[2][Notes 3] and the process which led to Moses becoming identified as the author of the Torah may have been influenced by three factors: first, by a number of passages in which he is said to write something, frequently at the command of God, although these passages never appear to apply to the entire five books; second, by his key role in four of the five books (Genesis is the exception); and finally, by the way in which his authority as lawgiver and liberator of Israel united the story and laws of the Pentateuch.[28][Notes 4]

Rabbinic tradition to the modern period

The Babylonian Talmud, an encyclopedia of Jewish scholarship composed between 200 and 500 CE, states that "Moses wrote his own book and the section concerning Balaam."[9][Notes 5] The medieval sage Maimonides (c.1135–1204) enshrined this in his Thirteen Principles of Faith (a summary of the required beliefs of Judaism), the 8th of which states: "I believe with perfect faith that the entire Torah presently in our possession is the one given to Moses."[10] The rabbis explained that God wrote the Torah in heaven before the world was created, in letters of black fire on parchment of white fire, and that Moses received it by divine dictation, writing the exact words spoken to him by God.[29] The rabbis also explained how the Torah was handed down to later generations: "Moses received the Torah from Sinai and transmitted it to Joshua, Joshua to the Elders, the Elders to the Prophets, and the Prophets transmitted it to the men of the Great Assembly," who in turn transmitted it to the rabbis.[1] (The Great Assembly, according to Jewish tradition, was called by Ezra to ensure the accurate transmission of the Torah of Moses, when the Jews returned from exile).[30] Orthodox rabbis therefore say that thanks to this chain of custodians the Torah of today is identical with that received by Moses, not varying by a single letter.[1]

The rabbis were aware that some phrases in the Torah do not seem to fit with divine dictation of a pre-existent text, and this awareness accounts for a second tradition of how the divine word was transmitted: God spoke and Moses remembered the divine words and wrote them down afterwards, together with some explanatory phrases of his own.[8] This explanation is a minority one, but it explains, for example, why every step in the description of the construction of the Tabernacle is followed by the phrase, "As the Lord commanded Moses."[31] There were also passages which seemed impossible for Moses to have written, notably the account of his own death and burial in last verses of Deuteronomy: the Talmud's answer is that "Joshua wrote ... [the last] eight verses of the Torah,"[6] yet this implied that the Torah was incomplete when Moses handed it to Israel; the explanation of rabbi Shimon bar Yochai was that the verses were indeed by Moses, but written "with tears in his eyes" as God dictated to him this description of his end.[6] More serious were a few passages which implied an author long after the time of Moses, such as Genesis 12:6, "The Canaanite was then in the land," implying a time when the Canaanites were no longer in the land.[32] Abraham ibn Ezra (c.1092–1167) made a celebrated comment on this phrase, writing that it contains "a great secret, and the person who understands it will keep quiet;"[32] the 14th century rabbi Joseph ben Samuel Bonfils responded that Moses had written this and similar passages, as he was a prophet, but that it made no difference whether they were by him or some later prophet, "since the words of all of them are true and inspired."[33] Finally, there were a few passages which implied that Moses had used pre-existing sources: a section of the Book of Numbers (Numbers 10:35–36) is surrounded in the Hebrew by inverted nuns (the equivalent of brackets) which the rabbis said indicated that these verses were from a separate book, the Book of Eldad and Medad.[34][Notes 6]

Biblical scholars today agree almost unanimously that the Torah is the work of many authors over many centuries.[12] A major factor in this rejection of the tradition of Mosaic authorship was the development of the documentary hypothesis by Julius Wellhausen in the 19th century, which understood the Pentateuch as a composite work made up of four "sources," or documents, compiled over centuries in a process that was not concluded until long after Moses' death.[35] The documentary hypothesis aroused understandable opposition from traditional scholars. One of the most significant was David Zvi Hoffmann (1843–1921), who attempted to defend Mosaic authorship by demonstrating that the sources identified by the documentary hypothesis were, in fact, pre-exilic; if this were proven, he believed, then the hypothesis itself was dis-proven.[36] The most he would concede to the proponents of the hypothesis was that Moses may have written various scrolls over his career and that these may have been collated and united before his death.[37]

Another important Jewish scholar, and one still active, is David Weiss Halivni (b.1927): he has developed a theory of Chate'u Yisrael, literally, "Israel has sinned", which states that the originally monotheistic Israelites adopted pagan practices from their neighbours and neglected the Torah of Moses, with the result that it became "blemished and maculated;" only on the return from Babylon did the people once again accept the Torah, which was then recompiled and edited by Ezra as evidenced in Ezra–Nehemiah and Talmudic and Midrashic sources, which indicate that Ezra played a role in editing the Torah.[38] He further states that while the text of the Torah was corrupted, oral tradition was preserved intact, which is why the Oral Law appears to contradict the Biblical text in certain details.[38]

Menachem Mendel Kasher (1895–1983), taking a different approach, accepted the documentary hypothesis but adapted it to the Mosaic tradition, pointing to certain traditions of the Oral Torah which show Moses quoting Genesis prior to the epiphany at Sinai; based on a number of Bible verses and rabbinic statements, he therefore suggested that Moses made use of documents authored by the Patriarchs when redacting that book.[39] This view is supported by some rabbinical sources and medieval commentaries which recognize that the Torah incorporates written texts and divine messages from before and after the time of Moses.[40]

Christian tradition

The Christian scriptures depict Jesus himself to have recognised Moses as the author of at least some portions of the Pentateuch (e.g., the Gospel of John, verses John 5:46-47) and the early Christians therefore followed the rabbis.[41][42] Like them, they addressed those passages which seemed to cast doubt on the Mosaic tradition: Jerome, for example, felt that "unto this day" implied an editor long after the time of Moses, presumably the 5th century BCE sage Ezra.[43] Martin Luther similarly concluded that the description of Moses' death was written by Joshua – but believed that the question itself was of no great importance.[44]

Jerome, Luther and others still believed that the bulk of the Pentateuch was written by Moses, even if a few phrases were not, but in the 17th century scholars began to seriously question its origins, leading Baruch Spinoza to declare that "the Pentateuch was not written by Moses but by someone else."[45] This conclusion had major implications, for as the 18th century Jewish scholar David Levi pointed out to his Christian colleagues, "if any part [of the Torah] is once proved spurious, a door will be opened for another and another without end."[42] As Levi had feared, the questioning of Mosaic authorship led to a profound skepticism towards the very idea of revealed religion,[46] and by the late 19th century scholars almost universally accepted that the Book of Deuteronomy dated not from the time of Moses but from the 7th century BCE, with the Pentateuch as a whole being compiled by unknown editors from various originally distinct source-documents.[47] Mainline Protestant Churches were the first to accept this and started using biblical criticism already from the 18th century.

The Catholic Church initially rejected such position: a decree of the Pontifical Biblical Commission of 1906, entitled De mosaica authentia Pentateuchi ("On the authenticity of the Mosaic authorship of the Pentateuch") stated that mosaic authorship of the Pentateuch was not a subject of discussion.[48]

Things gradually started to change in the '40s. In 1943, Pope Pius XII issued the encyclical Divino afflante Spiritu which encouraged scholars to investigate the sacred texts utilizing such resources as recent discoveries in archaeology, ancient history, linguistics, and other technical methods. On January 16, 1948, cardinal Emmanuel Célestin Suhard, secretary of the Pontifical Biblical Commission, responded to a question about the origin of the Pentateuch:

There is no one today who doubts the existence of these sources or refuses to admit a progressive development of the Mosaic Laws due to social and religious conditions of later time…. Therefore, we invite Catholic scholars to study these problems, without prepossession, in the light of sound criticism and of the findings of other sciences connected with the subject matter.

Christian support for Mosaic authorship is now limited largely to conservative Evangelical circles.[49] This is tied to the way Evangelicals view the unity and authority of scripture: in the words of the Zondervan Encyclopedia of the Bible, "Faith in Christ and faith in the books of the OT canon stand or fall together [because] Christ and the apostles ... took the Pentateuch as Mosaic [and] put their seal on it as Holy Scripture."[13] Nevertheless, the majority of contemporary Evangelicals, while accepting that some or much of the Pentateuch can be traced to Moses or traditions about him, pay little attention to the question of authorship.[50]

    • Deuteronomy 31:9: "Moses wrote this law and gave it to the priests, the sons of Levi, the ones carrying the Ark of the Covenant of the Lord" and Deuteronomy 31:24: "Moses ... finished writing the words of this law on a scroll." It is not clear just what Moses wrote, but it is usually taken to be the collection of laws that make up Deuteronomy 5–30.
    • Deuteronomy 31:22: "Moses wrote down this song on that day." The "song" is presumably Deuteronomy 32, the Song of Moses.
