When was the first synod of Catholic bishops?
Synod of Bishops in the Catholic Church
On 15 September 1965, as the Council was drawing to a close, Pope Paul VI established the Synod of Bishops, noting that "the Ecumenical Council ... gave Us the idea of permanently establishing a special Council of bishops, with the aim of providing for a continuance after the Council of the great abundance of benefits that We have been so happy to see flow to the Christian people during the time of the Council as a result of Our close collaboration with the bishops." The Pope sought "to make ever greater use of the bishops' assistance in providing for the good of the universal Church" and to enjoy "the consolation of their presence, the help of their wisdom and experience, the support of their counsel, and the voice of their authority." This preempted action by the Council and made the Synod "immediately and directly" subject to papal authority, ensuring that it would be strictly an advisory body. The Synod of the Bishops does not constitute collegial governance of the Church, but represents a collaboration with the Pope: it discusses topics proposed to it and makes recommendations, but does not settle questions or issue decrees, unless the Pope grants it deliberative power in certain cases.
Roman Catholic Diocese of Kotor
The first documented bishop of Cattaro was Paulus, who participated in the Council of Chalcedon in 451. The next mention of the Diocese of Cattaro was 530, when it is mentioned as a suffragan of the Archdiocese of Salona (Solin). The late Antiquity era, relatively the early Christian origin of the bishopric of Cattaro, is testified by an early Christian baptistery from the late 5th or early 6th centuries, discovered in an archeological examination of the Church of Saint Maria of Rijeka (Crkva sv. Marije od Rijeke) following the 1979 earthquake where the probable foundations of the first cathedral in Cattaro was discovered with remains, such as the cathedra and ciborium from the 6th century.
