Is there really such a thing as the "Judeo-Christian tradition"?

These days, the term "the Judeo-Christian tradition" is most often meant to evoke "those religious, ethical, or cultural values or beliefs regarded as being common to both Judaism and Christianity." So although Judaism and Christianity have a common ancestry, they both became "religions of the books" ― albeit quite different sets of books and, most importantly, interpreted in radically different ways. Leaving "Judeo-Christianity" behind The Jews, Israel and Jerusalem have thus become central to modern American and Australian conservative Protestant thinking about the end of the world and the return of Christ. The term "Judeo-Christian tradition" continues the suppression of Jewishness by hiding the essential differences between Judaism and Christianity, one of which is that each denies the validity of the other.
