According to the Sacred Tradition of the Orthodox Church, at the time of her Dormition, the Theotokos was buried by the Twelve Apostles in Jerusalem. Three days later, St. Thomas the Apostle, who had been delayed and unable to attend the funeral, arrived and asked to have one last look at the Virgin Mary. When he and the other apostles arrived at Mary's Tomb, they found that her body was missing. According to some accounts, the Virgin Mary appeared at that time and gave her belt (cincture) to the Apostle Thomas.
Today, there is celebrated in some places a little known feast named "The Placing of the Venerable Belt of the Most Holy Mother of God in the Constantinople Blakhernae Church." This took place twice. First, during the reign of the emperor Arcadius (395‑408). Second, during the reign of emperor Leo the Wise (886-911). In commemoration of the miraculous occurrences attributed to the belt, the Feast of the Placing of the Venerable Belt of the Most Holy Mother of God was established.
Pray for the Intercession of the Mother of God. She will protect you and help to keep you on the path of Christ.
