 Dear Shirahadasha, Please AT LEAST consider looking up terms in Wiki itself before you make statements. Canon from Greek kanon ""rule"" (perhaps originally from kanna ""reed"", cognate to cane) is used in various meanings. There is no Jewish entry here http://en.wikipedia.org/wiki/Canon. There is however a ""Biblical canon"" which includes a Jewish canon section. However there are rules on why some books are included in TaNaKh, and some are not. There is NO evidence in JEWISH sources that there EVER was a 'canon' in the Christian sense of the word. Most deduction is based on non-Jewish sources and modern academic research. Therefore you can not call TaNaKh a canon just so it can fall into the same definition as Christian works. This is particularly true since the TaNaKh is not consistently used by Christianity to 'rule' on issues of dogma, and the Christian canon is not used at all in Jewish halacha."
