The term Judeo-Christian is used to group Christianity and Judaism together, either in reference to Christianity's derivation from Judaism, Christianity's recognition of Jewish scripture to constitute the Old Testament of the Christian Bible, or values supposed to be shared by the two religions. The term Judæo Christian first appeared in the 19th century as a word for Jewish converts to Christianity. The term has received much criticism, largely from Jewish thinkers, as relying on and perpetuating inherently antisemitic notions of supersessionism, as well as glossing over fundamental differences between Jewish and Christian thought, theology, culture and practice.
In the United States, the term was widely used during the Cold War in an attempt to suggest that the U.S. had a unified American identity which was opposed to communism.
The use of the term "Abrahamic religions" to refer to the common grouping of faiths which are attributed to Abraham (Islam, the Baháʼí Faith, Samaritanism, Druzism, and other faiths in addition to Judaism and Christianity) is also sometimes seen as problematic.[1]
