Before the military events imposed a second postponement of the Council, the delegates concluded an important decree on the Eucharist that defined the actual presence of Christ as opposed to the interpretation of Huldrych Zwingli, head of the Swiss reform, and the doctrine of transubstantiation, contrary to that of Luther`s consubstantiation. The sacrament of penance was defined in detail, extreme incompetence (later the salting of the sick) and decrees on ephèdite jurisdiction and clerical discipline were promulgated. Meanwhile, German Protestants called for a revision of all the previous doctrinal decrees of the Council and wanted a declaration that the authority of a council was greater than that of the Pope. Council of Trent, 19th World Council of the Roman Catholic Church, in three parts from 1545 to 1563. Inspired by the Reformation, the Council of Trent was very important for its comprehensive decrees on self-reformation and for its dogmatic definitions that clarified virtually all the doctrines challenged by Protestants. Despite internal conflicts and two protracted interruptions, the Council was an important element of the counter-reform and played a decisive role in the revitalization of the Roman Catholic Church in many parts of Europe. The French monarchy boycotted the entire Council until the last minute, when a delegation led by Karl de Guise, cardinal of Lorraine, finally arrived in November 1562. The first outbreak of the French religious wars took place at the beginning of the year and the French Church, faced with a large and powerful Protestant minority in France, experienced iconoclasm with regard to the use of sacred images. Such concerns were not primary in the Italian and Spanish Church. [Clarification needed] The introduction at the last minute of a decree on sacred images was a French initiative, and the text, which was never discussed on the council`s ground or which dealt with the theologians of the Council, was based on a French project.  By the bull Benedictus Deus, dated January 26, 1564, but promulgated on June 30, Pope Pius IV confirmed without modification all the decrees of the Council and ordered their implementation. The first official edition of the decrees was printed on 18 March 1564 in Rome by Paolo Manuzio.
The Pope banned the publication of glosses or comments about them, and on August 2, 1564, he founded the Congregation of the Council to interpret them. He summed up the most important teachings of the Council in the profession of Fidei Tridentina, on which all university professors (10 November 1564) and prelates (13 November 1564) had to swear. Support for the implementation of the decrees was sought and provided by the leaders of the Catholic states: Spain, Portugal, Venice and Poland-Lithuania in 1564, the Swiss Catholic cantons in 1565 and the Catholic states of the Empire in 1566. When the king and the guardian general of France repeatedly refused to confirm Trent`s decrees, the French bishops met on their own and did so in 1615. Provincial councils have implemented Trent decrees at the local level. The decrees of the six provincial councils of Milan (1565-1582) under Carlo Borromeo (1538-1584) and, in 1582, acta Ecclesiae Mediolanensis published the model throughout Catholic Europe for much of the provincial and diocesan laws of application.
