This was done to clean up the image of the church after Rodrigo Borgia.
Rodrigo Borgia (Pope Alexander VI) Had basically destroyed the Catholic Church.
It was ripe with corruption. At this time they also started holding
seminaries to teach the young priests they had the actual meaning of the
church. They started new orders or sects. These where brought on to
purify the church more from the worldly excesses of the secular
Renaissance church. It also involved spiritual movements whose ministry
focused on interior conversion to Christ, the deepening of prayer and
commitment to God's will.
