The Cluny reform movement was a religious reform movement. It began in Cluny, France in 910. There were a variety of reasons for the decline of Western monasticism. Poverty, invasions, and the dependence on nobles led to this decline. The reform movement tried to reverse this trend.
There were many reforms made at Cluny that restored the rule of St. Benedict. One reform was to have public worship be a critical part of Christian life. The Cluniac monks devoted themselves to religious practice. This included the celebration of Holy Mass and the singing of Psalms. Sacred music and religious celebrations were promoted. The use of silence was encouraged to allow for deep reflection. These practices allowed the Cluniac monastery to be known for its holiness. Other monasteries decided to follow the practices of the Cluniac monastery. The Cluniac monastery was able to fight the practice of acquiring pastoral offices for money. It also confronted the lack of morals of the secular clergy.
The Cluniac reform brought significant changes in religious practices and beliefs to the Catholic Church.
