Hierarch Symeon Of Thessalonica

Saint Symeon of Thessalonica was a distinguished Byzantine theologian, liturgist, and ecclesiastical writer of the late 14th–early 15th century, and Archbishop of Thessalonica. Born in Constantinople, he took monastic vows and lived for a time as a solitary monk, likely at the monastery of Sts. Callistus and Ignatius Xanthopoulos, where he absorbed the hesychast theology of St. Gregory Palamas, of which he remained a staunch adherent throughout his life. Consecrated Archbishop of Thessalonica between May 1416 and April 1417, he governed the see for thirteen years until his death. His episcopate coincided with a tragic period: the city was besieged by the Ottoman Turks and briefly ceded to Venetian control, a transfer of authority Symeon, as a fervent opponent of Latin influence, resisted. In June 1422 he slipped out of the city to seek imperial help in Constantinople but was forced to return. Symeon left an extensive liturgical legacy — treatises on the sacraments, the order of divine services, and the meaning of Orthodox worship. He died, most likely in September 1429, shortly before Thessalonica finally fell to the Ottomans in March 1430. His feast is kept on September 15 (Julian) / September 28 (Gregorian).
