Name three church practices that led to calls of reform within the Roman Catholic Church by the A.D. 900s?

according to quizlet.com some of the reasons that they had to reform was because:
- some church leaders became worldly and corrupt
-many people found the sale of indulgences unacceptable
-the selling of indulgences
i still believe that today churches are corrupt they still need to be changed, to me (personally) some of the things they teach are wrong. my brother is very much a church person and he will call me a demon because of my religion and say that i am not his sister because i am gay. i also went to a summer camp and kids tried burning me because i was a "witch" and when i was in the woods with some suppose friends they hurt me and left me there. God would want them to be accepting and understanding
i also have good experience too tho i have met christian people who dont judge be because of the way i live my life, and they are proud of me.
sorry for my ranting
