The
Mishnah, compiled at the end of the 2nd century CE, describes a debate over the status of some books of Ketuvim, and in particular over whether or not they render the hands
ritually impure.
Yadaim 3:5 calls attention to a debate over
Song of Songs and Ecclesiastes. The ''Megillat Ta'anit
, in a discussion of days when fasting is prohibited but that are not noted in the Bible, mentions the holiday of Purim. Based on these, and a few similar references, Heinrich Graetz concluded in 1871 that there had been a Council of Jamnia (or Yavne in Hebrew) which had decided Jewish canon sometime in the late 1st century (c.'' 70–90). This became the prevailing scholarly consensus for much of the 20th century. W. M. Christie was the first to dispute this popular theory in 1925.
Jack P. Lewis wrote a critique of the popular consensus in 1964.
Raymond E. Brown largely supported Lewis in his review, as did Lewis' discussion of the topic in 1992's
Anchor Bible Dictionary. Sid Z. Leiman made an independent challenge for his University of Pennsylvania thesis published later as a book in 1976, in which he wrote that none of the sources used to support the theory actually mentioned books that had been withdrawn from a canon, and questioned the whole premise that the discussions were about canonicity at all, stating that they were actually dealing with other concerns entirely. Other scholars have since joined in and today the theory is largely discredited. Some scholars argue that the Jewish canon was fixed earlier by the
Hasmonean dynasty. Thus, there is no scholarly consensus as to when the Jewish canon was set. ==References==
