What was important about the Oratorian Movement?

The Oratorian Movement began around the late fifteenth or early sixteenth century, as part of the Catholic Reformation. Generally, the movement is dated in the early sixteenth century because St. Philip Neri, a Florentine who organized the movement in Rome, is credited as its founder. However, some believe that St. Philip was influenced by the ideas of St. Catherine of Genoa, a member of the powerful Guelph family who turned her life over to charitable service after a mystical experience.
For those who believe that Catherine's ideas were instrumental in St. Philip's organization of the oratory, it is significant that this order of the Catholic Church was founded on the ideas of a woman.
Catherine had been a devout follower of St. Augustine's writings since girlhood. Her ideas were rooted not only in spiritual development, but also in more secular values, such as education and charity for the poor and sick.
St. Philip's ideas of how to reform the Church were more specific to the institution and to religious doctrine. Like Martin Luther, he wanted the Scriptures to be more accessible to the laity. As a result, in his prayer group, he read Scripture in the vernacular, or common language, instead of Latin. Unlike Martin Luther, he was less concerned with structural and political reform and was more concerned with the inner transformation of Catholics. Conversion was dependent, in his view, on returning to the simplicity of the Gospels and a communal approach to worship.
Given the standing of the Catholic Church at the time, the Oratorian Movement was very important. It sought to reorient people to true Christian values of charity, asceticism, and community.
It is possible, too, that the Oratorian Movement, along with other reformist orders, was instrumental in ending corrupt church practices, such as simony. Simony was the practice of buying church offices. The Catholic Church had allowed this since the ninth century, but the practice dwindled after the sixteenth century due to the secularization of church property. The purchase of indulgences was another common practice that disappeared with reform. In exchange for money, people were partially or fully forgiven for their sins. The sale of indulgences, which had been particularly offensive to Martin Luther, was abolished by Pope Pius V in 1567.
The Oratorian Movement, like the Jesuit Movement, restored interest in classical education. However, the Oratorians wanted to establish educational institutions based on the classical curriculum throughout Europe and wished to make the institutions accessible to all who wanted to learn.
The Oratorians sought to use the resources of the Catholic Church to create a more egalitarian society in which everyone would receive the care they needed. They also encouraged the personal relationship with God that Martin Luther had advocated for.
