Yes but most priests will not allow non-catholic functions in their buildings.
In the Protestant church the system would be called doctrine or Theology. In the Catholic church it is catechism or dogma.
The Council of Trent was held to address the Protestant Reformation and to reform and clarify the teachings and practices of the Catholic Church. It aimed to define Catholic doctrine, address abuses within the Church, and assert the authority of the Pope.
There were many different cities where Church councils were held due to issues facing the Catholic Church. Some of the more famous ones are the Council of Trent (addressed the issue the Protestant Reformation and created the seven sacraments) and the two modern vatican councils 1 and 2 that were held in Rome at the Vatican.

Until 1517, there were only two branches of Christianity; the Roman Catholic Church, which had the Pope as its head, and the Eastern Catholic Church, also known as the Orthodox Catholic Church, which was led by the Patriarch of Constantinople (later called Istanbul). If you were Christian, you were Catholic. In 1517, a Catholic Monk named Martin Luther nailed a list of 95 things he found wrong with the Church on the door of his parish church in Wittenburg, Germany (although lately there has been some question whether or not he actually and literally Nailed them). These were the 95 Thesis that were the basis of the Protestant Reformation. The "Protestant Reformation" was so called because Martin Luther, and the people who followed him, Protested the injustice and downright Blasphemy that they saw in the Catholic Church. There were all sorts of practices of the Church with which they disagreed, but the two Basic ideas that inspired the Protestant Reformation were (1) the idea that Every person had personal access to God, and had no need of a Priest to mediate with God for him/her, and (2) the premise that Faith alone was sufficient for Salvation. The Catholic Church held, and still does, that a combination of Faith and Service (works) was necessary. The churches that carried on these beliefs are called Protestant, and the people who attend are known as Protestants.
The Council of Trent was the most significant event of the Counter-Reformation. It reaffirmed Catholic doctrines and practices, addressed corruption in the Church, and reformed the clergy. This council had a lasting impact on the Catholic Church and its response to the Protestant Reformation.
The difference between them is that the Catholic Reformation was the response to the Protestant Reformation. The Protestanst accused the Catholic Church of indulgences (paying for your sins to essentially be erased), being able to pay for your religious post, and to be able to have more than one post at a time, and many other scandals. Martin Luther nailed his 95 Thesis to the Church door in Wittenberg and from then, the Protestant Reformation started and eventually, the Church held the Council of Trent, whose goal was to purify the Church. The Jesuits were formed from the Catholic Reformation. The Jesuits were formed by St. Ignatius of Loyola and they converted people to Catholicism. They were considered one of the bright lights of the Catholic Reformation.
