John VIII of Constantinople (John XiphilinosGreek:Ἰωάννης Ξιφιλῖνος;c. 1010 – 2 August 1075), a native ofTrebizond, was a Byzantineintellectual,[1]jurist,[1] andEcumenical Patriarch of Constantinople from 1064 to 1075. He was the uncle ofJohn Xiphilinus, the Epimator. He is considered "an innovator in the field of the methodology ofjurisprudential research".[2]
John was born in Trebizond to theXiphilinos family. He pursued studies at theUniversity of Constantinople and eventually becamenomophylax of itsSchool of Law. Later he became a monk and was eventually selected by EmperorConstantine X Doukas (1059–1067) to succeedConstantine III of Constantinople as the Ecumenical Patriarch of Constantinople.
In 1072, John VIII presided over an assembly of metropolitans and archbishops at the oratory ofSaint Alexius in which the question of the election of bishops to vacant sees was discussed.Michael I of Constantinople had forbidden metropolitans who were resident in Constantinople from participating in such elections. John, however, recognised that metropolitans sometimes had to remain for a long period in the capital due to ecclesiastical business or illness. The assembly with John's consent decreed that metropolitans who gave the patriarch advance notification of their intent could again vote while resident in Constantinople.[3] After his death, his remains were buried at the monastery of Angourion on 2 August 1075.[4]
John VIII wrote ahagiography of SaintEugenios of Trebizond.[5]
John VIII has been canonised in theEastern Orthodox Church and his feast day is celebrated on 30 August.
