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.
