"Now, Luther's theory was that if everyone just returned directly to the scriptures, they would see the one single truth, and the church would be restored to its original simplicity.
Yeah, no. I have a message to the restorers of history. There is no original simplicity!
The thing is, once you start making scripture accessible to everyone and tell them that their opinions are just as good as those of the clergy, what happens is that people start, you know, having different interpretations of what religious truth is.
So, Luther’s protests started creating spin-offs: the Zwinglians, and the Calvinists, and the Anabaptists. And then the spin-offs had their own spin-offs.
It’s like how first there was Iron Man, and then there was The Avengers, and then, you know, like an Avengers TV show, pretty soon we’re gonna have Ant Man get his own movie. The Protestant Reformation is pretty much just the exact same thing as the comic universe, but no Thor, because he’s pagan.
Anyway, many of these new denominations will be familiar to you: the Anglicans, the Puritans, the Quakers, the Presbyterians, the Methodists, the Baptists.
Each of these new Protestant churches thought that it new the one true way to worship God, and that, you know, everyone else was going to Hell, and this led to some fighting. And also some disemboweling."
John Green said it best.
