The church splitting into two sides arguing about whether on how to get into heaven. By doing good deeds or just giving the church money and saying you believe.
The side of the church that is stealing money from the people and lying to them about certain things in the church.
Martin Luther nailing his 95 theses to the door of the church telling why and how both sides of the church are doing wrong in some ways.
After what Martin Luther did it broke the church, even more, making about 2 thousand church jobs open, leaving priest uneducated and ill-equipped.
Today the church is still split into two sides with one being Protestant and the other side being Catholic. It still continues to split today and believing their own things. Catholics saying only doing good gets you into heaven and protestant believing only saying you only believe in god will help.
The protestant still doing what they believe s still right and being their own church while the Christian stay them.
