Why can't Christians have their own state like Israel?

Answer 1

After the conversion of the Roman Empire to Christianity, the Roman Empire was the Christian state. when it divided into the Eastern (Byzantine) and Western empires, both of them were Christian states. After the fall of the western empire, King Charlimagne established his Holy Roman Empire as a Christian State. This empire eventually shrank, evolving into the Austrian Empire, but all of the Royal Families of Europe are descended from Charlimagne and all of their countries were, at least nominally, Christian countries with state churches. The United States was founded, in significant part, to get away from the tyranny of state churches. Ask the average Israeli how they feel about the official state-affiliated rabbinate in Israel before you put too much time into wishing for the return of any kind of state church in the Western world. But note, of course, that there are still state churches in most of Europe. In England, for example, the Church of England, the Catholic Church, the United Synagogue, and an equivalent Islamic group are "state churches" that get tax money. Baptists, Methodists, Reform Jews and others with no official status may form churches, but they don't get a state subsidy.
