I think you mean monotheism. That simply means the belief in one God. Mono means "one" and theos is the greek word for God. Thus monotheism means "one God".

How many Church Councils were held during 312-800 AD?

There were seven Ecumenical Councils during this time period. There were any number of Church Councils if you count all the local Councils, but I don't think anyone has ever compiled a list of local councils world-wide for the first millennium. First Ecumenical Council: Nicaea I (325) The Council of Nicaea lasted two months and twelve days. Three hundred and eighteen bishops were present. Hosius, Bishop of Cordova, assisted as legate of Pope Sylvester. The Emperor Constantine was also present. To this council we owe The Creed (Symbolum) of Nicaea, defining against Arius the true Divinity of the Son of God (homoousios), and the fixing of the date for keeping Easter (against the Quartodecimans). Second Ecumenical Council: Constantinople I (381) The First General Council of Constantinople, under Pope Damasus and the Emperor Theodosius I, was attended by 150 bishops. It was directed against the followers of Macedonius, who impugned the Divinity of the Holy Ghost. To the above-mentioned Nicene Creed it added the clauses referring to the Holy Ghost (qui simul adoratur) and all that follows to the end. Third Ecumenical Council: Ephesus (431) The Council of Ephesus, of more than 200 bishops, presided over by St. Cyril of Alexandria representing Pope Celestine I, defined the true personal unity of Christ, declared Mary the Mother of God (theotokos) against Nestorius, Bishop of Constantinople, and renewed the condemnation of Pelagius. Fourth Ecumenical Council: Chalcedon (451) The Council of Chalcedon - 150 bishops under Pope Leo the Great and the Emperor Marcian - defined the two natures (Divine and human) in Christ against Eutyches, who was excommunicated. Fifth Ecumenical Council: Constantinople II (553) The Second General Council of Constantinople, of 165 bishops under Pope Vigilius and Emperor Justinian I, condemned the errors of Origen and certain writings (The Three Chapters) of Theodoret, of Theodore, Bishop of Mopsuestia and of Ibas, Bishop of Edessa; it further confirmed the first four general councils, especially that of Chalcedon whose authority was contested by some heretics. Sixth Ecumenical Council: Constantinople III (680-681) The Third General Council of Constantinople, under Pope Agatho and the Emperor Constantine Pogonatus, was attended by the Patriarchs of Constantinople and of Antioch, 174 bishops, and the emperor. It put an end to Monothelitism by defining two wills in Christ, the Divine and the human, as two distinct principles of operation. It anathematized Sergius, Pyrrhus, Paul, Macarius, and all their followers. Seventh Ecumenical Council: Nicaea II (787) The Second Council of Nicaea was convoked by Emperor Constantine VI and his mother Irene, under Pope Adrian I, and was presided over by the legates of Pope Adrian; it regulated the veneration of holy images. Between 300 and 367 bishops assisted.


Where is the town Roman Catholic leadership discussed church reforms?

It's just Catholic, not Roman Catholic. Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is never used by the official Catholic Church. Not to pick on you, but the Catholic Church has been around for a long time (2,000 years) and has been constantly reforming due to the fact that she is made up entirely of sinful human beings. Usually reform came about through the Ecumenical Councils which were named after the towns that they were held: . First Ecumenical Council: Nicaea I (325) The Council of Nicaea lasted two months and twelve days. Three hundred and eighteen bishops were present. Hosius, Bishop of Cordova, assisted as legate of Pope Sylvester. The Emperor Constantine was also present. To this council we owe The Creed (Symbolum) of Nicaea, defining against Arius the true Divinity of the Son of God (homoousios), and the fixing of the date for keeping Easter (against the Quartodecimans). . Second Ecumenical Council: Constantinople I (381) The First General Council of Constantinople, under Pope Damasus and the Emperor Theodosius I, was attended by 150 bishops. It was directed against the followers of Macedonius, who impugned the Divinity of the Holy Ghost. To the above-mentioned Nicene Creed it added the clauses referring to the Holy Ghost (qui simul adoratur) and all that follows to the end. . Third Ecumenical Council: Ephesus (431) The Council of Ephesus, of more than 200 bishops, presided over by St. Cyril of Alexandria representing Pope Celestine I, defined the true personal unity of Christ, declared Mary the Mother of God (theotokos) against Nestorius, Bishop of Constantinople, and renewed the condemnation of Pelagius. . Fourth Ecumenical Council: Chalcedon (451) The Council of Chalcedon - 150 bishops under Pope Leo the Great and the Emperor Marcian - defined the two natures (Divine and human) in Christ against Eutyches, who was excommunicated. . Fifth Ecumenical Council: Constantinople II (553) The Second General Council of Constantinople, of 165 bishops under Pope Vigilius and Emperor Justinian I, condemned the errors of Origen and certain writings (The Three Chapters) of Theodoret, of Theodore, Bishop of Mopsuestia and of Ibas, Bishop of Edessa; it further confirmed the first four general councils, especially that of Chalcedon whose authority was contested by some heretics. . Sixth Ecumenical Council: Constantinople III (680-681) The Third General Council of Constantinople, under Pope Agatho and the Emperor Constantine Pogonatus, was attended by the Patriarchs of Constantinople and of Antioch, 174 bishops, and the emperor. It put an end to Monothelitism by defining two wills in Christ, the Divine and the human, as two distinct principles of operation. It anathematized Sergius, Pyrrhus, Paul, Macarius, and all their followers. . Seventh Ecumenical Council: Nicaea II (787) The Second Council of Nicaea was convoked by Emperor Constantine VI and his mother Irene, under Pope Adrian I, and was presided over by the legates of Pope Adrian; it regulated the veneration of holy images. Between 300 and 367 bishops assisted. . Eighth Ecumenical Council: Constantinople IV (869) The Fourth General Council of Constantinople, under Pope Adrian II and Emperor Basil numbering 102 bishops, 3 papal legates, and 4 patriarchs, consigned to the flames the Acts of an irregular council (conciliabulum) brought together by Photius against Pope Nicholas and Ignatius the legitimate Patriarch of Constantinople; it condemned Photius who had unlawfully seized the patriarchal dignity. The Photian Schism, however, triumphed in the Greek Church, and no other general council took place in the East. . Ninth Ecumenical Council: Lateran I (1123) The First Lateran Council, the first held at Rome, met under Pope Callistus II. About 900 bishops and abbots assisted. It abolished the right claimed by lay princes, of investiture with ring and crosier to ecclesiastical benefices and dealt with church discipline and the recovery of the Holy Land from the infidels. . Tenth Ecumenical Council: Lateran II (1139) The Second Lateran Council was held at Rome under Pope Innocent II, with an attendance of about 1000 prelates and the Emperor Conrad. Its object was to put an end to the errors of Arnold of Brescia. . Eleventh Ecumenical Council: Lateran III (1179) The Third Lateran Council took place under Pope Alexander III, Frederick I being emperor. There were 302 bishops present. It condemned the Albigenses and Waldenses and issued numerous decrees for the reformation of morals. . Twelfth Ecumenical Council: Lateran IV (1215) The Fourth Lateran Council was held under Innocent III. There were present the Patriarchs of Constantinople and Jerusalem, 71 archbishops, 412 bishops, and 800 abbots the Primate of the Maronites, and St. Dominic. It issued an enlarged creed (symbol) against the Albigenses (Firmiter credimus), condemned the Trinitarian errors of Abbot Joachim, and published 70 important reformatory decrees. This is the most important council of the Middle Ages, and it marks the culminating point of ecclesiastical life and papal power. . Thirteenth Ecumenical Council: Lyons I (1245) The First General Council of Lyons was presided over by Innocent IV; the Patriarchs of Constantinople, Antioch, and Aquileia (Venice), 140 bishops, Baldwin II, Emperor of the East, and St. Louis, King of France, assisted. It excommunicated and deposed Emperor Frederick II and directed a new crusade, under the command of St. Louis, against the Saracens and Mongols. . Fourteenth Ecumenical Council: Lyons II (1274) The Second General Council of Lyons was held by Pope Gregory X, the Patriarchs of Antioch and Constantinople, 15 cardinals, 500 bishops, and more than 1000 other dignitaries. It effected a temporary reunion of the Greek Church with Rome. The word filioque was added to the symbol of Constantinople and means were sought for recovering Palestine from the Turks. It also laid down the rules for papal elections. . Fifteenth Ecumenical Council: Vienne (1311-1313) The Council of Vienne was held in that town in France by order of Clement V, the first of the Avignon popes. The Patriarchs of Antioch and Alexandria, 300 bishops (114 according to some authorities), and 3 kings - Philip IV of France, Edward II of England, and James II of Aragon - were present. The synod dealt with the crimes and errors imputed to the Knights Templars, the Fraticelli, the Beghards, and the Beguines, with projects of a new crusade, the reformation of the clergy, and the teaching of Oriental languages in the universities. . Sixteenth Ecumenical Council: Constance (1414-1418) The Council of Constance was held during the great Schism of the West, with the object of ending the divisions in the Church. It became legitimate only when Gregory XI had formally convoked it. Owing to this circumstance it succeeded in putting an end to the schism by the election of Pope Martin V, which the Council of Pisa (1403) had failed to accomplish on account of its illegality. The rightful pope confirmed the former decrees of the synod against Wyclif and Hus. This council is thus ecumenical only in its last sessions (XLII-XLV inclusive) and with respect to the decrees of earlier sessions approved by Martin V. . Seventeenth Ecumenical Council: Basle/Ferrara/Florence (1431-1439) The Council of Basle met first in that town, Eugene IV being pope, and Sigismund Emperor of the Holy Roman Empire. Its object was the religious pacification of Bohemia. Quarrels with the pope having arisen, the council was transferred first to Ferrara (1438), then to Florence (1439), where a short-lived union with the Greek Church was effected, the Greeks accepting the council's definition of controverted points. The Council of Basle is only ecumenical till the end of the twenty-fifth session, and of its decrees Eugene IV approved only such as dealt with the extirpation of heresy, the peace of Christendom, and the reform of the Church, and which at the same time did not derogate from the rights of the Holy See. (See also the Council of Florence.) . Eighteenth Ecumenical Council: Lateran V (1512-1517) The Fifth Lateran Council sat from 1512 to 1517 under Popes Julius II and Leo X, the emperor being Maximilian I. Fifteen cardinals and about eighty archbishops and bishops took part in it. Its decrees are chiefly disciplinary. A new crusade against the Turks was also planned, but came to naught, owing to the religious upheaval in Germany caused by Luther. . Nineteenth Ecumenical Council: Trent (1545-1563) The Council of Trent lasted eighteen years (1545-1563) under five popes: Paul III, Julius III, Marcellus II, Paul IV and Pius IV, and under the Emperors Charles V and Ferdinand. There were present 5 cardinal legates of the Holy See, 3 patriarchs, 33 archbishops, 235 bishops, 7 abbots, 7 generals of monastic orders, and 160 doctors of divinity. It was convoked to examine and condemn the errors promulgated by Luther and other Reformers, and to reform the discipline of the Church. Of all councils it lasted longest, issued the largest number of dogmatic and reformatory decrees, and produced the most beneficial results. . Twentieth Ecumenical Council: Vatican I (1869-1870) The Vatican Council was summoned by Pius IX. It met 8 December, 1869, and lasted till 18 July, 1870, when it was adjourned; it is still (1908) unfinished. There were present 6 archbishop-princes, 49 cardinals, 11 patriarchs, 680 archbishops and bishops, 28 abbots, 29 generals of orders, in all 803. Besides important canons relating to the Faith and the constitution of the Church, the council decreed the infallibility of the pope when speaking ex cathedra, i.e. when as shepherd and teacher of all Christians, he defines a doctrine concerning faith or morals to be held by the whole Church. . Twenty-first Ecumenical Council: Vatican II ( 1962-1965)

What is an Ecumenical Council and why are such councils important?

An Ecumenical Council is a Council called by the Pope of all the Bishops in the world to discuss a particular problem or heresy, or group of problems or heresies. If approved by the Holy Father, their rulings are usually infallible (when dealing with matters of faith and morals). The last Ecumenical Council was a little different: the Second Vatican Council was called not to deal with any impending heresies but to call the Church to be more vigorous and up-to-date is spreading the faith outside of the Church. . Such Councils are very important as they are the work of the Holy Spirit and they show us the way in which to deal with problems and live our lives as good Christians. The Ecumenical Councils: First Ecumenical Council: Nicaea I (325) The Council of Nicaea lasted two months and twelve days. Three hundred and eighteen bishops were present. Hosius, Bishop of Cordova, assisted as legate of Pope Sylvester. The Emperor Constantine was also present. To this council we owe The Creed (Symbolum) of Nicaea, defining against Arius the true Divinity of the Son of God (homoousios), and the fixing of the date for keeping Easter (against the Quartodecimans). Second Ecumenical Council: Constantinople I (381) The First General Council of Constantinople, under Pope Damasus and the Emperor Theodosius I, was attended by 150 bishops. It was directed against the followers of Macedonius, who impugned the Divinity of the Holy Ghost. To the above-mentioned Nicene Creed it added the clauses referring to the Holy Ghost (qui simul adoratur) and all that follows to the end. Third Ecumenical Council: Ephesus (431) The Council of Ephesus, of more than 200 bishops, presided over by St. Cyril of Alexandria representing Pope Celestine I, defined the true personal unity of Christ, declared Mary the Mother of God (theotokos) against Nestorius, Bishop of Constantinople, and renewed the condemnation of Pelagius. Fourth Ecumenical Council: Chalcedon (451) The Council of Chalcedon - 150 bishops under Pope Leo the Great and the Emperor Marcian - defined the two natures (Divine and human) in Christ against Eutyches, who was excommunicated. Fifth Ecumenical Council: Constantinople II (553) The Second General Council of Constantinople, of 165 bishops under Pope Vigilius and Emperor Justinian I, condemned the errors of Origen and certain writings (The Three Chapters) of Theodoret, of Theodore, Bishop of Mopsuestia and of Ibas, Bishop of Edessa; it further confirmed the first four general councils, especially that of Chalcedon whose authority was contested by some heretics. Sixth Ecumenical Council: Constantinople III (680-681) The Third General Council of Constantinople, under Pope Agatho and the Emperor Constantine Pogonatus, was attended by the Patriarchs of Constantinople and of Antioch, 174 bishops, and the emperor. It put an end to Monothelitism by defining two wills in Christ, the Divine and the human, as two distinct principles of operation. It anathematized Sergius, Pyrrhus, Paul, Macarius, and all their followers. Seventh Ecumenical Council: Nicaea II (787) The Second Council of Nicaea was convoked by Emperor Constantine VI and his mother Irene, under Pope Adrian I, and was presided over by the legates of Pope Adrian; it regulated the veneration of holy images. Between 300 and 367 bishops assisted. Eighth Ecumenical Council: Constantinople IV (869) The Fourth General Council of Constantinople, under Pope Adrian II and Emperor Basil numbering 102 bishops, 3 papal legates, and 4 patriarchs, consigned to the flames the Acts of an irregular council (conciliabulum) brought together by Photius against Pope Nicholas and Ignatius the legitimate Patriarch of Constantinople; it condemned Photius who had unlawfully seized the patriarchal dignity. The Photian Schism, however, triumphed in the Greek Church, and no other general council took place in the East. Ninth Ecumenical Council: Lateran I (1123) The First Lateran Council, the first held at Rome, met under Pope Callistus II. About 900 bishops and abbots assisted. It abolished the right claimed by lay princes, of investiture with ring and crosier to ecclesiastical benefices and dealt with church discipline and the recovery of the Holy Land from the infidels. Tenth Ecumenical Council: Lateran II (1139) The Second Lateran Council was held at Rome under Pope Innocent II, with an attendance of about 1000 prelates and the Emperor Conrad. Its object was to put an end to the errors of Arnold of Brescia. Eleventh Ecumenical Council: Lateran III (1179) The Third Lateran Council took place under Pope Alexander III, Frederick I being emperor. There were 302 bishops present. It condemned the Albigenses and Waldenses and issued numerous decrees for the reformation of morals. Twelfth Ecumenical Council: Lateran IV (1215) The Fourth Lateran Council was held under Innocent III. There were present the Patriarchs of Constantinople and Jerusalem, 71 archbishops, 412 bishops, and 800 abbots the Primate of the Maronites, and St. Dominic. It issued an enlarged creed (symbol) against the Albigenses (Firmiter credimus), condemned the Trinitarian errors of Abbot Joachim, and published 70 important reformatory decrees. This is the most important council of the Middle Ages, and it marks the culminating point of ecclesiastical life and papal power. Thirteenth Ecumenical Council: Lyons I (1245) The First General Council of Lyons was presided over by Innocent IV; the Patriarchs of Constantinople, Antioch, and Aquileia (Venice), 140 bishops, Baldwin II, Emperor of the East, and St. Louis, King of France, assisted.

Fourteenth Ecumenical Council: Lyons II (1274) The Second General Council of Lyons was held by Pope Gregory X, the Patriarchs of Antioch and Constantinople, 15 cardinals, 500 bishops, and more than 1000 other dignitaries. It effected a temporary reunion of the Greek Church with Rome. The word filioque was added to the symbol of Constantinople and means were sought for recovering Palestine from the Turks. It also laid down the rules for papal elections. Fifteenth Ecumenical Council: Vienne (1311-1313) The Council of Vienne was held in that town in France by order of Clement V, the first of the Avignon popes. The Patriarchs of Antioch and Alexandria, 300 bishops (114 according to some authorities), and 3 kings - Philip IV of France, Edward II of England, and James II of Aragon - were present. The synod dealt with the crimes and errors imputed to the Knights Templars, the Fraticelli, the Beghards, and the Beguines, with projects of a new crusade, the reformation of the clergy, and the teaching of Oriental languages in the universities. Sixteenth Ecumenical Council: Constance (1414-1418) The Council of Constance was held during the great Schism of the West, with the object of ending the divisions in the Church. It became legitimate only when Gregory XI had formally convoked it. Owing to this circumstance it succeeded in putting an end to the schism by the election of Pope Martin V, which the Council of Pisa (1403) had failed to accomplish on account of its illegality. The rightful pope confirmed the former decrees of the synod against Wyclif and Hus. This council is thus ecumenical only in its last sessions (XLII-XLV inclusive) and with respect to the decrees of earlier sessions approved by Martin V. Seventeenth Ecumenical Council: Basle/Ferrara/Florence (1431-1439) The Council of Basle met first in that town, Eugene IV being pope, and Sigismund Emperor of the Holy Roman Empire. Its object was the religious pacification of Bohemia. Quarrels with the pope having arisen, the council was transferred first to Ferrara (1438), then to Florence (1439), where a short-lived union with the Greek Church was effected, the Greeks accepting the council's definition of controverted points. The Council of Basle is only ecumenical till the end of the twenty-fifth session, and of its decrees Eugene IV approved only such as dealt with the extirpation of heresy, the peace of Christendom, and the reform of the Church, and which at the same time did not derogate from the rights of the Holy See. (See also the Council of Florence.) Eighteenth Ecumenical Council: Lateran V (1512-1517) The Fifth Lateran Council sat from 1512 to 1517 under Popes Julius II and Leo X, the emperor being Maximilian I. Fifteen cardinals and about eighty archbishops and bishops took part in it. Its decrees are chiefly disciplinary. A new crusade against the Turks was also planned, but came to naught, owing to the religious upheaval in Germany caused by Luther. Nineteenth Ecumenical Council: Trent (1545-1563) The Council of Trent lasted eighteen years (1545-1563) under five popes: Paul III, Julius III, Marcellus II, Paul IV and Pius IV, and under the Emperors Charles V and Ferdinand. There were present 5 cardinal legates of the Holy See, 3 patriarchs, 33 archbishops, 235 bishops, 7 abbots, 7 generals of monastic orders, and 160 doctors of divinity. It was convoked to examine and condemn the errors promulgated by Luther and other Reformers, and to reform the discipline of the Church. Of all councils it lasted longest, issued the largest number of dogmatic and reformatory decrees, and produced the most beneficial results. Twentieth Ecumenical Council: Vatican I (1869-1870) The Vatican Council was summoned by Pius IX. It met 8 December, 1869, and lasted till 18 July, 1870, when it was adjourned; it is still (1908) unfinished. There were present 6 archbishop-princes, 49 cardinals, 11 patriarchs, 680 archbishops and bishops, 28 abbots, 29 generals of orders, in all 803.

What is the Roman Catholic Church group that met to discuss church reform is?

It's just Catholic, not Roman Catholic. Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church.

XVI. COUNCIL OF CONSTANCE Years: 1414-1418 The Council of Constance was held during the great Schism of the West, with the object of ending the divisions in the Church.

What reforms did the Catholic Church ultimately make?

The "ultimate" reform of the Church will not come until the return of Our Blessed Savior at the end of the world, when the Church, as His Bride, accompanies Him to heaven. Until then, the Church, itself, cannot reform - per se - as it is the Mystical Body of Christ, although its members are always in need of reform. That latter reform usually comes about during the great councils of the Church, of which there have been 21 Ecumenical Councils to date: The 21 Ecumenical Councils I. FIRST COUNCIL OF NICAEA Year: 325 Summary: The Council of Nicaea lasted two months and twelve days. Three hundred and eighteen bishops were present. Hosius, Bishop of Cordova, assisted as legate of Pope Sylvester. The Emperor Constantine was also present. To this council we owe the Nicene Creed, defining against Arius the true Divinity of the Son of God (homoousios), and the fixing of the date for keeping Easter (against the Quartodecimans).

What attempts at reform were made by the Roman Catholic Church?

The Church did a lot more than try to reform itself, well, it's members, it did a great deal in that direction: primarily as a result of the protestant revolt which showed up the glaring deficiencies in things like clerical education (with Martin Luther as the prime example of what an uneducated man ordained to the priesthood can do). The two primary reasons for the reform were the definitive determination of the doctrines of the Church in answer to the heresies of the Protestants; a further object was the execution of a thorough reform of the inner life of the Church by removing the numerous abuses that had developed in it.from A Catholic Dictionary, edited by Donald Attwater,Second edition, revised 1957The Counter-Reformationis 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 Neriand Charles Borromeoin 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 Carmelitesunder 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 deSales 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.
