First Council of the Lateran

Roman Catholic synod of 1123

The First Council of the Lateran was the 9th ecumenical council recognised by the Catholic Church. The first ecumenical council to be held in Western Europe & the first since the Great Schism of 1054, it was convoked by Pope Callixtus II in December 1122, immediately after the Concordat of Worms. The council sought to bring an end to the practice of the conferring of ecclesiastical benefices by people who were laymen, free the election of bishops and abbots from secular influence, clarify the separation of spiritual and temporal affairs, re-establish the principle that spiritual authority resides solely in the Church and abolish the claim of the Holy Roman Emperor to influence papal elections.
