Josyf Veliamyn Rutsky

Joseph Velamin-Rutski (born as Ivan Velyaminov; , , ) - (1574 – 5 April 1637) was the "Metropolitan of Kiev, Galicia and all Ruthenia" in the Ruthenian Uniate Church — a sui juris Eastern Catholic Church in full communion with the Holy See. He reigned from 1613 to 1637. He worked to build the Greek Catholic Church in the first few decades after the Union of Brest of 1596; he also reformed the Basilian monks.

Early life Joseph Velyaminov-Rutski (father Feliks Velyaminov from Moscow and mother Bahumila Korsak) lived in Polish–Lithuanian Commonwealth, had Ruthenian origins and was noble and Calvinist. Joseph's father Feliks Velyaminov belonged to the Rurik dynasty; he escaped Russian Tsardom during the reign of Ivan the Terrible. Ivan Velyaminov was born in 1574 and, according to a use of noble families, was named after the estate where he was born, Ruta, thus he was named Ivan Velaminov-Rutski.

At 17 he moved to Prague where he studied under the Jesuits and converted to the Catholic Church of Latin Rite against the will of his parents. From 1593-1596, Rutski studied philosophy at Wurtzburg. After the death of his father, his mother, who remained a Calvinist, opposed Rutski's desire to enter into religious life and stopped supporting his studies. Rutski continued his studies in the St. Athanasius Greek College in Rome, where he was authorized by Pope Clement VIII to change from the Latin Rite to the Byzantine Rite. Rutski completed his studies in 1603.

In 1617, Metropolitan Rutski united a number of monasteries into the Congregation of the Holy Trinity of the Order of Saint Basil the Great.

Following the erection of the parallel metropolis in 1620 — the Metropolis of Kiev, Galicia and all Ruthenia — he worked for unity with those bishops who remained loyal to the Ecumenical Patriarchate of Constantinople.

He died on 5 February 1637 and is buried in Vilnius. His cause for beatification began in 1937.
