Lateran Council (769)

Constantine II was a layman who was elevated to the Papal See by his brother Toto of Nepi and a group of Tuscan nobles.

[3] He was opposed by another antipope, Philip, who was installed by an envoy of the King of the Lombards, Desiderius, and reigned just for one day, 31 July 768.

[4] With the election of Pope Stephen III on 1 August 768,[5] and the forcible removal of the antipopes, Stephen III had sent a request to Pepin the Short, asking for bishops well versed in the Scriptures and in canon law to assist at a synod which would seek to prevent any repeat of the events that led to the elevation of the antipopes.

[1] The first sessions of the Council, lasting two days, were dedicated to reviewing the activities of the antipope Constantine II, in which Wilichar of Sens took a leading role.

He pointed to two episcopal elections, those of Sergius, Archbishop of Ravenna, and Stephanus, Bishop of Naples, where the successful candidates had been laymen.

[16] Once, however, the election had been held by the clergy, and a pope selected, the Roman army and people were to greet and acknowledge the pope-elect before he was escorted to the Lateran Palace.

[16] However, the synod also stated that if those who had been consecrated bishops by Constantine were re-elected via a canonical method, they might be reconciled and restored to the episcopate by the Pope.

Reviewing the writings of the Church Fathers, the Council decreed that it was permissible and desirable for Christians to venerate icons.

[18] Finally, it collected additional texts in support of the veneration of icons, including portions of a letter from the three eastern patriarchs to Pope Paul I.
