The Council of Trent, which lasted from December 13, 1545 to December 4, 1563 and covered topics such as the Canon of Scripture, how to deal with the emerging heresy of Protestantism, and Justification.
The Council that initiated the Catholic Reformation, also known as the Counter-Reformation, was the Council of Trent. It was convened by the Catholic Church in response to the Protestant Reformation and took place from 1545 to 1563. This Council addressed doctrinal and disciplinary reforms within the Church.
If you mean: "......in reaction to ther Reformation movement started by Luther and Calvin", the answer is that the name is the Counter-Reformation, started by the Roman Catholic Council of Trent, held between 1545 and 1563.
The meeting of church leaders in the 1500s that aimed to clearly define Catholic doctrines for the Catholic Reformation is known as the Council of Trent.
The Counter Reformation
There technically is no "Roman" Catholic Church, the Catholic Church has been around for twenty centuries and has had dozens of ecumenical councils in that time. You would have to narrow it down to a specific time period.
Catholic AnswerPrimarily, it evolved as a response to the Catholic revolt, and the main thrust of it began with the Council of Trent, with the Church restoring order in its teaching and organization in response to the chaos caused by the protestants and their wholesale revolt from Christ's teaching in His Church. from A Catholic Dictionary, edited by Donald Attwater, Second edition, revised 1957The Counter-Reformation is the name given to the Catholic movement of reform and activity which lasted for about one hundred years from the beginning of the Council of Trent (q.v., 1545), and was the belated answer to the threatening confusion and increasing attacks of the previous years.
The counter reformation
It was not Henry 5, but the 8th. He began the Reformation by closing the Catholic Church and taking their assets. The church he created was the Church of England.
The Council of Trent was an ecumenical council convened by the Roman Catholic Church in Trento, the principle city of the Bishopric of Trent, now a part of modern Italy, thus its name. The council had 25 sessions from Dec. 13, 1545 to Dec. 4, 1563. The first 8 session were held in Trent, the next three in Bologna, and the last 14 back in Trent.
The protestant reformation is the name of the religious reform movement that divided the Roman Catholic Church.
Reginald Pole was the last Catholic Archbishop of Canterbury during the Counter-Reformation period, serving from 1556 until his death in 1558. Pole played a significant role in attempting to reconcile England with the Catholic Church during the tumultuous times of the Reformation.
Catholic AnswerThe main effect of the "reformation" or protestant revolt was the loss of thousands of souls who, because of their princes, were denied the sacraments that Jesus Christ had established for their salvation. This resulted, over the centuries that followed in the loss of millions of souls. The counter-reformation or Catholic reform was reform in the Catholic Church both in its head and members, resulting in great growth, numerous saints, new religious orders, new colleges, seminaries, better educated clergy, and a vibrant lay faithful. from the Catholic EncyclopediaThe term Counter-Reformation denotes the period of Catholic revival from the pontificate of Pope Pius IV in 1560 to the close of the Thirty Years' War, 1648. The name, though long in use among Protestant historians, has only recently been introduced into Catholic handbooks. The consequence is that it already has a meaning and an application, for which a word with a different nuance should perhaps have been chosen. For in the first place the name suggests that the Catholic movement came after the Protestant; whereas in truth the reform originally began in the Catholic Church, and Luther was a Catholic Reformer before he became a Protestant. By becoming a Protestant Reformer, he did indeed hinder the progress of the Catholic reformation, but he did not stop it.from A Catholic Dictionary, edited by Donald Attwater, Second edition, revised 1957The Counter-Reformation is the name given to the Catholic movement of reform and activity which lasted for about one hundred years from the beginning of the Council of Trent (q.v., 1545), and was the belated answer to the threatening confusion and increasing attacks of the previous years. It was the work principally of the Popes St. Pius V and Gregory XIII and the Council itself in the sphere of authority, of SS. Philip Neri and Charles Borromeo in the reform of the clergy and of life, of St. Ignatius and the Jesuits in apostolic activity of St. Francis Xavier in foreign missions, and of St. Teresa in the purely contemplative life which lies behind them all. But these were not the only names nor was it a movement of a few only; the whole Church emerged from the 15th century purified and revivified. On the other hand, it was a reformation rather than a restoration; the unity of western Christendom was destroyed; the Church militant (those still on earth) led by the Company of Jesus adopted offence as the best means of defence and, though she gained as much as she lost in some sense, the Church did not recover the exercise of her former spiritual supremacy in actuality.from Modern Catholic Dictionary by John A. Hardon, S.J. Doubleday & Co., Inc. Garden City, NY 1980A period of Catholic revival from 1522 to about 1648, better know as the Catholic Reform. It was an effort to stem the tide of Protestantism by genuine reform within the Catholic Church. There were political movements pressured by civil rules, and ecclesiastical movements carried out by churchmen in an attempt to restore genuine Catholic life by establishing new religious orders such as the Society of Jesus and restoring old orders to their original observances, such as the Carmelites under St. Teresa of Avila (1515-98). The main factors responsible for the Counter Reformation, however, were the papacy and the council of Trent (1545-63). Among church leaders St. Charles Borromeo (1538-84), Archbishop of Milan, enforced the reforms decreed by the council, and St. Francis de Sales of Geneva (1567-1622) spent his best energies in restoring genuine Catholic doctrine and piety. Among civil rulers sponsoring the needed reform were Philip II of Spain (1527-98) and Mary Tudor (1516-58), his wife, in England. Unfortunately this aspect of the reformation led to embitterment between England and Scotland, England and Spain, Poland and Sweden, and to almost two centuries of religious wars. As a result of the Counter Reformation, the Catholic Church became stronger in her institutional structure, more dedicated to the work of evangelization, and more influential in world affairs.
