Quick spread of Protestant beliefs:
Because of Luther's solid points about the Church's corruptness, many people converted to his new branch. This led the Chruch to try and gain back their followers by holding many dfferent events.

 
Counter-Reformation:
This action by the church is very important because if it wasn't for this, Catholicism would never recover from major rise of Protestantism.

 
Questioning of Church:
This is an important effect because if didn't start from the Luther's points, then the church would continue to be trick people.

 
Council of Trent:
This is quite important because of the Questioning of Church, then the church wouldn't have the chance to defend themselves and convince some people to convert back (or stay with them)

 
Re-emphaszing church's legitimacy:
Because of the Council of Trent, the church ws able to reform and convince people that Cahtolicism was still legit.

 
Calvinism:
John Calvin was able to create a whole new belief from Catholicism, which gave more people more options and have a new way to stay a good Christian.
