The Council of 1123 is reckoned in the series of Ecumenical councils by the Catholic Church. It was convoked by Pope Callixtus II in December, 1122, immediately after the Concordat of Worms. The Council sought to: (a) bring an end to the practice of the conferring of ecclesiastical benefices by people who were laymen (b) free the election of bishops and abbots from secular influence (c) clarify the separation of spiritual and temporal affairs (d) re-establish the principle that spiritual authority resides solely in the Church (e) abolish the claim of the emperors to influence papal elections.
