Is Christianity the Official Religion of Rome?

Constantine the Great in ancient Rome presided over this vast empire and he decided, all right, there's no way we can control all these people. And therefore, Christianity is going to be the official religion of Rome. So it was very much a political calculated political move by him. But when you have a situation, United States is very much like Rome in that sense. It's a big country. There's lots of different people here. We're not going to unite under religion. We have to unite under something and thinking that you died under is our democracy and the American dream quote unquote doesn't make any sense for me.
