Education

Kossów was a descendant of a Ruthenian noble family. He studied at the Kyiv and Vilno Brotherhood schools and at the Lublin Jesuit Collegium and Zamość Academy before beginning to teach at the Vilno and Lviv Dormition brotherhood schools. After finishing his education, Kosiv accepted monastic vows at the Saint Trinity Monastery in Vilno. With the opening of the Kyiv Lavra School in 1631, Kosiv be its lecturer on the request of Metropolitan Petro Mohyla becoming its prefect. In 1632–1635 he was the first prefect at the Kyiv Collegium teaching courses on rhetoric and philosophy. At the same time in 1632 Kosiv joined the Kyiv Epiphany Brotherhood.

Bishop Sylvestr

In 1635 he became bishop of Mstislavl, Orsha, and Mahiliow. Following the Union of Brest, the eparchy of Mstislawl, Orsha, and Mahiliow became the only Eastern Orthodox eparchy within the Grand Duchy of Lithuania. In 1647 he became the metropolitan of Kyiv. It happened just before the Khmelnytsky Uprising, a time of uncertainty in Ukraine and in the Ruthenian church.

Kossów himself was strongly opposed to union with Tsardom of Russia, and also against unreserved alliance with Poland. He condemned the 1654 treaty of Pereyaslav between the Cossack Hetmanate and the Tsardom of Muscovy. Despite being critical of some of the policies of the Ukrainian Cossacks, he attempted to rectify the situation and along with the Patriarch of Jerusalem Paiseus gave Bohdan Khmelnytsky a hero's welcome when he entered Kyiv on 2 January 1649 (Old Style 23 December 1648). Kossów strived for an independent Ruthenian Orthodox Church that would be only under the jurisdiction of the Patriarch of Constantinople, and he fought against the subjugation of the Kyiv metropolate to Moscow.

In 1650 Sylvestr headed a delegation of the Orthodox clergy and Kyiv voivode Adam Kysil to the Sejm in Warsaw and contribute to ratification of the 1649 treaty of Zboriv.
