Our Father among the Saints Thomas, Patriarch of Constantinople
Life
Thomas was a hierarch of the Church of Constantinople who occupied the patriarchal throne in the opening years of the seventh century. He rose through the clergy of Hagia Sophia, serving first as a deacon and then as sakellarios, the office of sacristan or treasurer of the Great Church, under Patriarch John IV the Faster, and he retained that position under John's successor, the Patriarch Cyriacus.
Elected Ecumenical Patriarch in 607 after the death of Cyriacus, Thomas governed the Church for slightly more than three years until his death in 610. His brief tenure is remembered chiefly for his close association with the ascetic Theodore of Sykeon and for a portent, reported in the synaxarion, that was understood to foreshadow the turmoil that would shortly overtake the Byzantine Empire.

Theodore of Sykeon and the Portent of the Crosses
The sources connect Thomas closely with Saint Theodore of Sykeon, an ascetic of Galatia whom the patriarch held in great esteem; by tradition Thomas regarded him as a spiritual brother and asked his prayers that they might remain united in the life to come.
During Thomas's patriarchate, the synaxarion relates, the heavy processional crosses carried in churches of Asia began to shake and strike against one another. Theodore of Sykeon interpreted the phenomenon as a portent of coming discord within the Church, apostasy, barbarian invasions, and disaster for the Empire. On hearing these predictions, Thomas is said to have asked Theodore to pray that he might die before the foretold calamities came to pass.
Aftermath
The troubles foretold in Thomas's lifetime are recorded as following soon after his death. His successor, Patriarch Sergius I, embraced the heresy of Monothelitism, and war with Persia devastated Byzantine Asia Minor, leading to the fall of Jerusalem and the capture of the True Cross by the Persians.
