Thomas II (Greek: Θωμᾶς; died 15 November 669) was the Ecumenical Patriarch of Constantinople from 667 to 669. He had been ecumenically preceded by Patriarch Peter of Constantinople.[1] During the troubled times of the Christological disputes, he was Orthodox in his faith and teaching. He is commemorated by the Church on November 16. He was succeeded as ecumenical Patriarch by His All-Holiness John V of Constantinople.[2]
Little is known of his life. Thomas was in the service of the patriarchate in which he served as a scribe, a refendarius, a chancellor of the Patriarchate, and director of the Scala Gerokoeion and the Neapolis Ptochotropheion. Thomas was elected patriarch from the diaconate over six and a half months after the repose of his predecessor, Patriarch Peter. His consecration has been dated as on Holy Saturday in the year 665.
