It's an interesting time line. You began believing in the assumption AFTER the empire had made Roman Catholicism the state religion and After the followers of the cults of Cybelle and Isis had become parts of your church. Isn't it about this time that the celibacy of priests started to become a big issue?
Gregory the Great was Pope from 590-604 and I remember from some reading I did in his stuff in 1977 that he was asked about celibacy for the clergy in England, I conclude that it was still up in the air, though he was emphatically in favor of it. So you think he'd been hanging with the Cybele worshippers?
Of course, in Kolokotronis's Church celibacy os not an issue for the priests, as it also is not an issue for many rites of the "Catholic" church. So the Isis/Cybele infection (if any) was limited in scope.
My understanding is that Protestantism really took off around the time tobacco was introduced to England and Europe from America? Mere Coincidence? [Cue ominous music.] I don't think so.
Can you please site what year Catholicism was made the state religion of Rome btw?
Back to history class, WF. The state religion of the Roman Empire was NEVER Roman Catholicism. As a matter of fact, the Empire tended towards accepting a "broad diversity" of beliefs which included heresies. It did this for pretty much the same reason which underlay the Elizabethan Compromise, to keep the peace. You should also know that The Church, in Alexandria, Antioch, Constantinople, Jerusalem and Rome often found themselves in opposition to heretical Emperors, to the point of anthemizing those Emperors and/or loosing their patriarchates or even their heads over those oppositions. Whole Councils of The Church came out in opposition to various Emperors and won.
