Ecumenical Councils, for the most part, have dealt with heresies, from the first one at Nicaea, which dealt with the Arian heresy through the Council of Trent, which dealt with the protestant heresy. that has been their main function, which a few notable exemptions, the Second Vatican Council dealt with no heresies, nor even any doctrinal issues, it was strictly a pastoral council. Unfortunately, due to the climate of the times, and the deep vein of Modernism which was running underground at the time, heresy followed that Second Vatican Council.

Sorry, you are going to have to be a whole lot more specific, there have been 21 Ecumenical Councils who have discussed Church reform over the centuries, and innumerable local Councils, plus the Roman Curia.
The ecumenical council refers to a conference of the theological experts and the ecclesiastical dignitaries convened to settle and discuss matters of the various practices of the church. It is also called the oecumenical council.
Roman Catholic AnswerThe first Ecumenical Council of the Church was the First Council of Nicaea, which, unsurprisingly was held at Nicaea as Councils are named after the town or location where they are held.

Roman Catholic AnswerThere was no new "church of Trent". The Council of Trent was 19th of 21 general ecumenical councils of the Catholic Church, (not counting the Council of Jerusalem in the books of Acts): First Ecumenical Council: Nicaea I (325)Second Ecumenical Council: Constantinople I (381)Third Ecumenical Council: Ephesus (431)Fourth Ecumenical Council: Chalcedon (451)Fifth Ecumenical Council: Constantinople II (553)Sixth Ecumenical Council: Constantinople III (680-681)Seventh Ecumenical Council: Nicaea II (787)Eighth Ecumenical Council: Constantinople IV (869)Ninth Ecumenical Council: Lateran I (1123)Tenth Ecumenical Council: Lateran II (1139)Eleventh Ecumenical Council: Lateran III (1179)Twelfth Ecumenical Council: Lateran IV (1215)Thirteenth Ecumenical Council: Lyons I (1245)Fourteenth Ecumenical Council: Lyons II (1274)Fifteenth Ecumenical Council: Vienne (1311-1313)Sixteenth Ecumenical Council: Constance (1414-1418)Seventeenth Ecumenical Council: Basle/Ferrara/Florence (1431-1439)Eighteenth Ecumenical Council: Lateran V (1512-1517)Nineteenth Ecumenical Council: Trent (1545-1563)Twentieth Ecumenical Council: Vatican I (1869-1870)Twenty-first Ecumenical Council: Vatican II (1962-1965)All of these councils were councils called by the Holy Father and attended by as many bishops as he could get there. They were all guided by the Holy Spirit and approved by Rome so that their decisions are binding on all of Christ's Church. Each and everyone of them was called to deal with various heresies. Many of their decisions involved the first time a doctrine was actually "defined" for the simple reason that it was the first time it had seriously been called into question. There was no new church after Trent, just as there was no new church after Nicaea. Despite other opinions to the contrary, the Church of Rome was established by Christ and remained faithful to Him throughout the centuries. There is no "church of Trent".
Catholic AnswerNot counting the Council of Jerusalem, which is recorded in the Book of Acts, there have been twenty-one ecumenical Councils of the Church. They are listed at the link below.
Roman Catholic AnswerThe highest teaching authority in the Catholic Church is Jesus Christ. His Will is known through the twin authorities of Tradition and Scripture. These are interpreted for us by Ecumenical councils (councils of all the bishops ratified by the Holy Father) and by the Pope.
