>>2802050Roman imperial ideology had become universal by the time of Christianity's rise, Caracalla's edict is a good exemple of it, everyone in the empire (except women and slaves) became citizens. Afterwards what the roman didn't tolerate were christians, as their ideology contrasted directly with the imperial ideology (until it didn't anymore)
>>2802060You're right about mono/henotheism, but christianity is different in its desire to spread and expand, pagans didn't really try to force other people to their worship, and the romans tolerated and even integrated gods from other pantheons (Isis is a famous exemple) even neoplatonists tolerated other gods, viewing them as the inferior representation of Helios (Jupiter fell from favor during late antiquity) Paganism is less founded on a precise theology then the continuation of ancestral practices.
Christianity (exception gnosticism) is the exact opposite, the beliefs are what is important, not the practices in themselves. This means thats christianity's nature is to expand and spread the religion (same for Islam)
>>2802065The Transition from roman society to feudalism began with Augustus, with citizens losing many rights after his victory and the creation of a nobility.
While the church offered legitmaty for the late emperors and the early kings, they also became a counter power, something the emperors didn't really have (apart from the army couping from time to time).
The church encouraged obediance in power and revolt when their ennemies were.
