The greatest problem Rome had was unclear succession rights. Who should the next emperor be? Well, usually whoever could win the civil wars and avoid getting assassinated.
Oftentimes the emperor was a dictator who rose to power through dubious means, and so his greatest pressing cause was to justify why he was on the throne to begin with.
Emperors resorted to all kinds of crazy means to try to secure their often short-lived rule. Gladiator games, posting fliers, spreading rumors, buying people off. One popular meme was to attempt to claim divine status. Emperors like Eligabilus or Caligula attempted to create an imperial cult around themselves, with themselves as the directly appointed son of some diety they added to the panthon.
This came to a head in the Crisis of the Third Century. Rome had so many internal civil wars, assassinations, backstabs, that the entire empire almost collapsed. They went through several dozen emperors in as many years. It was finally stabilized in part by Aurelian's imperial cult around Sol Invictus. Using religion to quell dissent and unite everyone.
This was so effective that it became the standard. Soon Constantine decided to merge Sol Invictus with the religion of Christianity. That became the method of imperial rule.
Except the theocrats took it way too seriously and started unironically purging people according to the words of the ancient texts, rather than the plutocratic method of control that it was supposed to be. The empire collapsed.
That Catholic church emerged in the shambles of the empire to attempt to restart it, but this time, using religion instead of state power. There's a reason Vatican City is located in Rome, this is the new Roman Empire. They sought dominion over all the nations of Europe.
So you see, Christianity is really just macheavellian, globalist control mechanism. The entire history of it is about controlling people and securing empire.
