In 1702, Saint Demetrios, Metropolitan of Rostov, arrived at the Rostov cathedral and also visited the monastery of Saint James, Bishop of Rostov (November 27 and May 23).
He served the Divine Liturgy at the cathedral church of the Conception of the Most Holy Theotokos, after which he indicated to those present the site of his future burial on the right side of the temple. “Behold my resting place,” he said, “here I will settle for eternity.” Saint Demetrios reposed on October 28, 1709.
Contrary to the Saint's wishes, which he had expressed in his will, the clergy and people of Rostov asked the locum tenens of the patriarchal throne, Metropolitan Stephen Yavorsky of Ryazan, who had come for the funeral, to conduct the burial at the city's cathedral church.
Metropolitan Stephen insisted on burying the body of his deceased friend beside Saint Joasaph, who was Saint Demetrios's predecessor. However, a grave was not prepared until the arrival of Metropolitan Stephen, even though about a month had passed since the Saint's death.
Due to the urgent departure of Metropolitan Stephen from Rostov, a hastily constructed wooden frame was placed into the grave, in which the body of the Saint was buried on November 25. This circumstance, foreseen by the Providence of God, led to a quick uncovering of the relics.
In 1752 repairs were being made in the cathedral church of the monastery, and on September 21, the incorrupt body of Saint Demetrios was discovered. The place of burial had been affected by dampness, the oaken coffin and the writing on it were decayed, but the body of the Saint, and even his omophorion, sakkos, mitre and silken prayer rope were preserved undamaged.
After the discovery of his relics, Saint Demetrios began to heal many illnesses, and performed many miracles. When the Holy Synod was informed of these facts, it sent a Commitee: Metropolitan Sylvester of Suzdal and Archimandrite Gabriel of Simonov Monastery, to examine the relics of Bishop Demetrios and to verify the miraculous cures.
Upon the Committee's recommendation, a decree was issued by the Holy Synod on April 29, 1757 numbering Saint Demetrios, Metropolitan of Rostov among the saints, and designating the dates of his commemoration as October 28 (the day of his repose) and September 21 (the uncovering of his relics).
The Church of Russia also commemorates the Hierarchs Demetrios of Rostov, Metrophanes and Tikhon of Voronezh on July 19.
