Judeo-Christian

The term Judeo-Christian is used to group Christianity and Judaism together, either in reference to a shared history before Christianity split from Judaism, Christianity's recognition of Jewish scripture (constituting the Old Testament of the Christian Bible), or values supposed to be shared between them. 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 invoke a unified American identity that stood opposed to communism.

The term has received criticism, largely from Jewish thinkers, as relying on and perpetuating notions of supersessionism, as well as glossing over fundamental differences between Jewish and Christian thought, theology, culture and practice. Even using the more inclusive 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 sometimes seen as problematic.
