Fun fact about the early Catholic church is that, despite spending generations being persecuted by the Roman empire, it took less than 15 years under Theodosius I to go from “the empire is Catholic now” to “and also every other religion is banned.” You can literally read St. Augustine move from “state religious persecution is unacceptable” to “state religious persecution is cool actually” over his lifetime as Catholicism came to power. I’m sure there’s no broader lessons to be learned there
