of Chalcedon in the year 451. It repudiated the Eutychian doctrine of monophysitism, and set forth the Chalcedonian Definition, which describes the "full humanity and full divinity" of Jesus Christ, the Second Person of the Holy Trinity. Present at the council were 630 representatives from all the local Christian Churches. The meetings were quite contentious, and no decisive consensus could be reached. According to the Synaxarion of Constantinople, a collection of hagiographies, both parties wrote a confession of their faith and placed them on the breast of Saint Euphemia within her tomb. After three days the tomb was opened and the scroll with the Orthodox confession was seen in the right hand of St Euphemia while the scroll of the Monophysites lay at her feet. Relics When the persecution of Diocletian ended, the Christians laid Saint Euphemia's reputed relics in a golden sarcophagus, placed within a church that was dedicated to her. Her relics attracted crowds of pilgrims for centuries. Around the year 620, in the wake of the conquest of Chalcedon by the Persians under Khosrau I in the year 617, the relics of Saint Euphemia were transferred to a new church in Constantinople. There, during the persecutions of the Iconoclasts, her reliquary was said to have been thrown into the sea, from which it was recovered by the ship-owning brothers Sergios and Sergonos, who belonged to the Orthodox party, and who gave it over to the local bishop who hid them in a secret crypt. The relics were afterwards taken to the Island of Lemnos, and in 796 they were returned to Constantinople. The majority of her relics are still in the Patriarchal Church of St. George, in Istanbul. Feast days The primary feast day of Saint Euphemia, celebrated by both Eastern and Western Christians is September 16 in commemoration of her martyrdom. Additionally, Eastern Orthodox Christians commemorate her miracle at the Council of Chalcedon on July 11. In popular culture St. Euphemia is a widely venerated saint among all Eastern Orthodox Christians, not only for her virginity and martyrdom, but also for her strengthening of the Orthodox Faith, and her feast days are celebrated with special solemnity. Churches in her honor have been erected at many places.
