The Uncovering of the Relics of Saint Macarius of Kalyazin occurred on May 26, 1521. A merchant from the city of Dmitrov, Michael Voronkov, offered the means for the construction of a stone church to replace the decaying wooden one at the Kalyazin monastery.
The igumen of the monastery, Joasaph, set up a cross at the spot designated for the altar, and gave a blessing to dig the trench for the foundation. During the work a grave was discovered, exuding an ineffable fragrance. Igumen Joasaph immediately recognized the grave of the monastery’s founder, Saint Macarius, who reposed in the year 1483.
The brethren of the monastery and a crowd of people sang a Panikhida during the transfer of the coffin to the church. From that day the incorrupt relics of the saint began to work healings. A report about this was made to Metropolitan Daniel of Moscow (1522-1539), who convened a Council at Moscow. After examining testimony about the sanctity of Macarius, he established a Feast day for the newly-appeared saint. The relics were solemnly transferred to the church of the Holy Trinity.
Theodosius of Tver composed the service for the Uncovering of the Relics. Until 1547, Saint Macarius was venerated only at this monastery. During the Moscow Council of 1547 under Metropolitan Macarius (1543-1564), Saint Macarius of Kalyazin was numbered among the saints, and his name added to the calendar of other Russian saints to be celebrated throughout all of Russia.
The Life of Saint Macarius of Kalyazin is found under March 17, the day of his blessed repose.
