Friendly reminder that “Judeo-Christian” is Not A Thing, as a term it is misleading and offensive to Jews, and should never be used except in the sentence I am currently saying.
You may refer to “Abrahamic religions,” which means Judaism, Christianity, and Islam. If you’re not talking about all three of them, odds are excellent you’re really just talking about Christianity, and should just say so instead of dragging us Jews into it.
