We need to model the US more closely on Ancient Rome in the Imperial period back when it was working well!

Well, you have your Emperor, all you need now is something that looks like the things that were taught by Jesus Christ and then you have the other bit you want. Your history is somewhat awry. Augustus decreed a personality cult based on himself. He was no promoter of Christianity in any form.

My own view is that the worst thing that ever happened to the Church was for it to be taken over as a state religion by Emperor Constantine. Keep the Church out of politics.
