The Judeo Christian religion? What is that?
There is a Jewish religion and there are Christian religions. Most religions are/were an outgrowth of some other religion. Our country was founded by Christians.There were very few Jews in our country then. Yes, there were some Sephardic Jews in New Amsterdam early on and later New York and a group in Rhode Island but our country was founded by Christians.
It’s a way of showing harmony and avoiding nasty divisions.
Said to be how the early US made it from squabbling colonies to an admirable and exceptional Republic.
