Jewish responses
Response of Jews towards the “Judeo-Christian” concept has been mixed. In the 1930s, “In the face of worldwide antisemitic efforts to stigmatize and destroy Judaism, influential Christians and Jews in America labored to uphold it, pushing Judaism from the margins of American religious life towards its very center.”[13] During World War II, Jewish chaplains worked with Catholic priests and Protestant ministers to promote goodwill, addressing servicemen who, “in many cases had never seen, much less heard a Rabbi speak before.” At funerals for the unknown soldier, rabbis stood alongside the other chaplains and recited prayers in Hebrew. In a much publicized wartime tragedy, the sinking of the Dorchester, the ship’s multi-faith chaplains gave up their lifebelts to evacuating seamen and stood together “arm in arm in prayer” as the ship went down. A 1948 postage stamp commemorated their heroism with the words: “interfaith in action.”[8]
In the 1950s, “a spiritual and cultural revival washed over American Jewry” in response to the trauma of the Holocaust.[8] American Jews became more confident to be identified as different.
Two notable books addressed the relations between contemporary Judaism and Christianity, Abba Hillel Silver’s Where Judaism Differs and Leo Baeck’s Judaism and Christianity, both motivated by an impulse to clarify Judaism’s distinctiveness “in a world where the term Judeo-Christian had obscured critical differences between the two faiths.”[14] Reacting against the blurring of theological distinctions, Rabbi Eliezer Berkovits wrote that “Judaism is Judaism because it rejects Christianity, and Christianity is Christianity because it rejects Judaism.”[15] Theologian and author Arthur A. Cohen, in The Myth of the Judeo-Christian Tradition, questioned the theological validity of the Judeo-Christian concept and suggested that it was essentially an invention of American politics, while Jacob Neusner, in Jews and Christians: The Myth of a Common Tradition, writes, “The two faiths stand for different people talking about different things to different people.”[16]
Law professor Stephen M. Feldman looking at the period before 1950, chiefly in Europe, sees religious conflict as supersessionism:
Once one recognizes that Christianity has historically engendered antisemitism, then this so-called tradition appears as dangerous Christian dogma (at least from a Jewish perspective). For Christians, the concept of a Judeo-Christian tradition comfortably suggests that Judaism progresses into Christianity—that Judaism is somehow completed in Christianity. The concept of a Judeo-Christian tradition flows from the Christian theology of supersession, whereby the Christian covenant (or Testament) with God supersedes the Jewish one. Christianity, according to this myth, reforms and replaces Judaism. The myth therefore implies, first, that Judaism needs reformation and replacement, and second, that modern Judaism remains merely as a "relic". Most importantly the myth of the Judeo-Christian tradition insidiously obscures the real and significant differences between Judaism and Christianity.[17]
Role of Islam
Further information: Abrahamic religions
Advocates of the term “Abrahamic religion” since the second half of the 20th century have proposed a hyper-ecumenicism that emphasizes not only Judeo-Christian commonalities but that would include Islam as well (the rationale for the term “Abrahamic” being that while only Christianity and Judaism give the Hebrew Bible (Old Testament) the status of scripture, Islam does also trace its origins to the figure of Abraham as the “first Muslim”).
Advocates of this umbrella term consider it the “exploration of something positive” in the sense of a “spiritual bond” between Jews, Christians, and Muslims.[18]
