What events in ancient Judeo-Christian history laid the foundation for the principle of the separation of church and state in the United States of America?

Judeo-Christian is a term that groups Judaism and Christianity, either in reference to Christianity's derivation from Judaism or due to perceived parallels or commonalities shared between those two religions. [citation needed]. The term became prevalent towards the middle of the 20th century in the United States to link broader principles of Judeo-Christian ethics such as dignity of human life, adherence to the Abrahamic Covenant, common decency, and support of traditional family values.[1]

The concept of "Judeo-Christian values" in an ethical (rather than theological or liturgical) sense was used by George Orwell in 1939, with the phrase "the Judaeo-Christian scheme of morals."[2] It has become part of the "American civil religion" since the 1940s.

The term "Abrahamic religions" is used to include Bahá'ísm, Islam, Druze etc. as well as Judaism and Christianity. [3]
