The term Judeo-Christian is used to group Christianity and Judaism together, either in reference to Christianity's derivation from Judaism, Christianity's borrowing of Jewish Scripture to constitute the "Old Testament" of the Christian Bible, or due to the parallels or commonalities in Judaeo-Christian ethics shared by the two religions. The term "Judæo Christian" first appeared in the 19th century as a word for Jewish converts to Christianity.
In the United States, the term was widely used during the Cold War in an attempt to suggest that the United States had a unified American identity which was 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, instead, he suggested that it was essentially an invention of American politics.
The use of Abrahamic religions as a term for the common grouping of faiths which are attributed to Abraham, the Baháʼí Faith, Islam, Samaritanism, Druzism, and other faiths in addition to Judaism and Christianity, is also sometimes seen as problematic.
