It seems I wrote a fairly long reply.

Religions have two aspects - the literary context, and the context of the religion as it is practiced. When we look at these combined, Christianity at the large is a religion that supports and co-exists with the existing power structure rather than is overtly "rebellious". In the historical, and the modern context both. With the exception of North America and various evangelical sects spread through the globe.

To my understanding, in Islam the literary and the practical context match pretty well, as Quran was written as a sort of mystical field manual of administration and religious practice, in a very specific political situation. While the ideas expressed in the text are partly ancient, the body of work itself is only as old as the religion [0]. I agree up to a point - Islam is more like an administrators device than Christianity.

Christianity, on the other hand, in its' holy book combines a selected collection of ancient Judaistic texts with the content of the new testament. The tradition of religious practice evolved only after the texts were compiled [1] - which was upheld to be critical part of the religion for a millenia. Protestants seemingly denied the importance of tradition but actually just replaced it with their own culture of practice [2].

As for the protestants' "rebellious nature" - that really wasn't. Unless protestantianism existed harmoniously with the existing power structrure it was crushed. One of the culminations of this tension was the 30 years war [3].

Yes, the ideas of protestantianism rose from deep conviction and the moral impetus to overthrow old concepts. But practically it could only succeed when it co-existed and co-operated with the earthly power structure. (Hence, we get the protestant state churches in various countries [4].)

Or it could escape the old society all together ... to the new world.

Christianity in the North-America is quite a different thing than as practiced in the old world. The various sects that were persecuted in europe found home there and could thrive in relative freedom.

The critical part about this is that there was no state church. You could choose your religious community based on your conscience. Hence, I presume the evangelical aspects of Christianity can be more highlighed there. A considerable portion of the progenitors of North American christianity were the rebels, with no deep ties to the political power structure.

In Europe, the Church and the State ruled hand in hand for over a millenia, and only now this co-operation is starting to fragment. First the Catholic church with it's blood ties to the aristocracy, and then the protestant state churches herded the masses.

Especially in the first millenia, to large extent the church and state officers came from the same families. First sons of noble houses inherited the land, while the some of the later sons became priests. The main reason for the vows of selibacy was to stop a secondary church-based hereditary power structure from rising next to the feudal aristocracy.

"Resemblance to Hellenistic cults are superficial."

I was mainly referring to the philosophical and literary content of the new testament as it matches fairly well with the ethics of the greek philosophers.

As for the mystical content - I would claim the resemblance to older non-judaistic tradition is far deeper than superficial. For example for the worship of Virgin Mary, the image of the mother goddess was already powerfull and ancient [4]. I know later theologians integrated Mary to the church canon but I presume this was only after she was popular with the masses.
