Menas of Constantinople
Menas considered a saint in the Eastern Orthodox Church, was Patriarch of Constantinople appointed by the Byzantine emperor Justinian I in 536. Pope Agapetus I consecrated him to succeed Bishop Anthimus, who was a monophysite. He took a position against Origen. He was excommunicated in 547 and in 551 for taking positions counter to those held by the Pope; but in both cases the sentence of excommunication was quickly lifted. Menas' patriarchy represents the greatest extent of papal influence in Constantinople.
His feast day in both the Eastern Orthodox and Roman Catholic traditions is observed on August 25.
