Nikanor (Niesłuchowski)

On 18 July 1981 he retired. He died four years later in Białystok and was buried in the parish cemetery of the All Saints parish.

As an ordinary of the diocese of Białystok and Gdańsk, he unsuccessfully sought permission from the authorities to build a new Orthodox temple in Białystok, stressing that the existing churches were not sufficient to provide full pastoral care for the faithful. However, he only obtained permission to build a new Orthodox temple on a plot of land near the church of St. Mary Magdalene in Białystok. He refused to accept it, claiming that the existence of two sacred buildings in close proximity was pointless. He carried out a major renovation of the Cathedral of St. Nicholas in Białystok, and in 1979 he consecrated the new Orthodox Church of the Dormition of the Blessed Virgin Mary in Białystok-Starosielce

By the decision of the Holy Council of Bishops in 1966, he was appointed the Ordinary of the Białystok-Gdańsk diocese. Ingres to the Białystok cathedral took place on May 8, 1966. In 1978 he was given the office of archbishop, and two years later he was given the right to wear a diamond cross on a headgear.

In 1964, while still a white clergyman, he was made a bishop. After making his perpetual monastic vows, during which he took the monastic name of Nikanor, he became auxiliary bishop of the Warsaw-Bielsko diocese with the title of the bishop of Lublin. He remained so from 1965 to 1966. He took over the Białystok-Gdańsk cathedral in 1966, when the former Białystok bishop, Stefan, became the metropolitan of Warsaw and of all Poland after the death of Metropolitan Tymoteusz.

In 1953 he was one of the members of the PAKP delegation at the restitution ceremony of the Bulgarian Patriarchate.

On December 9, 1952, the metropolitan of Warsaw and all of Poland, Makary, presented to the council of bishops of the Polish Autocephalous Orthodox Church three candidates for clergy to accept bishop chirotony and take over the cathedral in Wrocław and Szczecin: Mikołaj Niesłuchowski, Jan Lewiarz and Archimandrite Stefan (Rudyk). From the presented proposals, the bishops chose Archimandrite Stefan.

He was ordained a priest as a white (married) clergyman. Widowed in 1944, when his wife Olga died during the Soviet-German fights for the village of Jaczno in the Białystok region. The clergyman himself was then injured.

In 1930 he graduated from the Theological Seminary in Vilnius. In 1934, he graduated from the Orthodox Theology Department of the University of Warsaw with a master's degree in Orthodox Theology.

Archbishop Nikanor, (secular birth name Mikołaj Niesłuchowski; 8 March 1909 - 19 February 1985) was the Archbishop of Białystok and Gdańsk.

He was born on 8 March 1909 in the village of Rowanicze in Belarus in the family of a psalmist. He graduated from primary school in Ostrówki in the Nesvizh poviat, where he arrived with his parents in 1912.
