   replaced Christian with

It has often been noted that many political concepts in the western world emerged out of Christianity, notably by Nietzsche and Carl Schmitt. That's probably not really directly a unique feature of Christianity but because religions themselves tend to co-evolve with successful states as narratives that help stabilise said states.

That isn't strictly true. Christianity has a concept of what should be dealt by God and what should be dealt with by man. The very term "Religion" is a Christian one as before that generally the state, religion, your life etc were all bound up as one. It wasn't until the Roman Empire did anyone even consider that these were separate.
