The opening as it read in 2005
Fourth Council of the Lateran was summoned by Pope Innocent III with his Bull of April 19 , 1213 .1The assembly took place in November, 1215 .2It was the 12th ecumenical council and is sometimes called "the General Council of Lateran" due to the attendance by seventy-one patriarchs and metropolitans, four hundred and twelve bishops , and nine hundred abbots and priors.3Innocent III stated his purposes as the defence of the Catholic faith, for the aid to the Crusader States in Palestine , and to establish the liberty of the Church from lay investiture and other lay interference. The pope presented to the council seventy decrees; these were considered along with measures against heretics , and the organisation of the Fifth Crusade . The council did little more than rubber-stamp the decrees presented to them. The decrees included: Exposition of the faith and of the dogma of transubstantiation Procedure and penalties against heretics and their protectors Proclamation of the papal primacy - After the pope, primacy is attributed to the patriarchial sees in the following order: Constantinople (at this time there was a Latin Patriarch ) Alexandria Antioch Jerusalem Rules on the conduct of the clergy including against irregularities: incontinence drunkenness hunting attendance at farces and histrionic exhibitions performing of surgical operations conducting trials by ordeal or combat the Omnis utriusque sexus (also called the Easter Duty), which commands every Christian who has reached the years of discretion to confess all their sins at least once a year to their priest Jews and Muslims shall wear a special dress to enable them to be distinguished from Christians.

1213 encumenical council The Fourth Council of the Lateran or Lateran IV was convoked by Pope Innocent III in April 1213 and opened at the Lateran Palace in Rome on 11 November 1215. Due to the great length of time between the council's convocation and its meeting, many bishops had the opportunity to attend this council, which is considered by the Catholic Church to be the twelfth ecumenical council . The council addressed a number of issues, including the sacraments , the role of the laity , the treatment of Jews and heretics , and the organization of the church . The decree mandating annual confession has been called "pehaps the most important legislative act in the history of the church." In the case of Jews and Muslims , this included compelling them to wear distinctive badges to prevent social contact "through error".The council is viewed by medievalists as both opening up many reforms, and as formalising and enforcing intolerance in European society, both to heretics and Jews, and thus playing a role in the development of systemic European antisemitism .
