Masquerouge said:What I also find really interesting in the Catholic Church history is the way it transformed from a completely rebellious faction of underground believers, rejecting all authorities and the Roman one in particular, into a very solid, very real temporal power that, in a way, became a supreme authority in the Middle-Ages, with its state, its leader, its army, its riches...
Interesting, but hardly unexpected, given that there was no temporal power to speak of in northern Itay in the Dark Ages. Little wonder that people like Gregory the Great found themselves having to act as, essentially, civil governors of the region, and generally doing as good a job as could be expected.
I don't know why you say that the early church was completely rebellious and rejected the Roman authorities, though. Have you read Romans 13?
