The term Judeo-Christian is used to group Christianity and Judaism together, either in reference to Christianity's derivation from Judaism, both religions' common use of the Bible, or due to perceived parallels or commonalities and shared values between the two religions.

The term Judæo Christian first appeared in the 19th century as a word for Jewish converts to Christianity. The German term Judenchristlich ("Jewish-Christian") was used by Friedrich Nietzsche to describe continuity between the Jewish and Christian world views.

The term became widely used in the United States during the Cold War to suggest a unified American identity opposed to communism. 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.

The related term "Abrahamic religions" includes the Baháʼí Faith, Islam, Druze etc. in addition to Judaism and Christianity.[1]
