Hell is simply a form of extortion where the victim volunteers the funds. The only "products" churches have are "salvation" and "damnation". Neither of which can be proven to actually exist. But hope for one and fear of the other keeps the Vatican's seventeen art galleries stocked.
You forgot penance and Purgatory. That was true, in the Late Roman Empire under Emperor Theodosius ... there was only one allowed religion ... his. Slap me shocked! This was a couple generations after Emperor Constantine, who made Christianity licit (but only the version he approved of, at the bishops conclave he approved, with bishops he approved of). Initially other religions were still licit. Not every religion, the Romans being totalitarian, they always reserved the right to punish you for disobedience, and practicing atheism, or a non-approved religion, was punishable, eventually by death. When Constantine made Christianity licit, he basically nationalized them ... only priests that he approved of could practice, and all of them became civil servants. That is how we got Sunday as an official holy day ... because as a Solar pagan, that was his favorite day of the week. In this Orthodox Christianity (primarily created by Constantine) there was salvation only thru the Church, salvation wasn't optional, and if you sinned, you had to do penance, or be kicked out, eventually in a monoculture, to be shunned by one and all. Confession hadn't been invented yet, but that was a great addition ... confessing to an agent of the State, once a week. The Irish invented that. Gotta control the narrative, in dictatorship-ville. Now we have Facebook.
So no, not just an ideological lock on people, but the authority of the State to enforce conformity. Something all us non-conformists, loath.
