Then the church solved that issue by telling people that they could actually get into heaven by paying. People got so pissed off that a sect splintered off, and I think that how we got Protestants.

OP here is referring to the fact that the Catholic church was selling indulgences (basically get out of purgatory free cards), and that is what led Martin Luther to publish the Ninety-five Theses, calling them out on it. This is generally considered to be the starting point for the Protestant Reformation.

They were pissed off with the hedonism and made catholicism but with fun being illegal and salvation through wageslavery

Paying for sin was called indulgences. At first, it was to quell other issues and make money. But then it just turned into a way to make money. Vast piles of money. Personal money, as you alluded.
