Council of Trent

The Council of Trent is reckoned by the Roman Catholic Church to be the Nineteenth Ecumenical Council of the universal church. It was held from December 13, 1545, to December 4, 1563 in the Italian city of Trent. Although called an Ecumenical Council, only Roman Catholics attended. Indeed it was called as a riposte to the growth of Protestantism.

It is considered one of the most important councils in the history of the Roman Catholic Church, establishing church doctrine in response to the Reformation and condemning Protestantism. It clearly specified Catholic doctrines on salvation, the sacraments and the Biblical canon, and standardized the Mass throughout the church, largely abolishing local variations. This became called the "Tridentine Mass", from the city's Latin name Tridentum.

Occasion, sessions, and attendance

In reply to the Papal bull Exsurge Domine of Pope Leo X (1520), Martin Luther had burned the document and appealed to a general council. In 1522, German diets joined in the appeal, and Charles V seconded and pressed it as a means of reunifying the Church and settling the controversy started by the Reformation. Pope Clement VII (1523-1534) was vehemently against the idea of a council, agreeing with Francis I of France. After the deliverances of Pope Pius II in his bull Execrabilis (1460) and his reply to the University of Cologne (1463), setting aside the theory of the supremacy of general councils laid down by the Council of Constance, it was the papal policy to avoid councils.
