Yuri Havryil Kolenda (Ukrainian: Юрі Гавриїл Коленда, Belarusian: Гаўрыла Календа, Polish: Gabriel Kolenda) (1606—1674) was the "Metropolitan of Kiev, Galicia and all Ruthenia"[a] in the Ruthenian Uniate Church — a sui juris Eastern Catholic Church in full communion with the Holy See.

[3] Returning to Lithuania, in 1640 Kolenda became the deputy of the Archbishop of Polotsk, Antin Sielava, who in 1641 became the Metropolitan of Kiev and head of the Church.

[6] In September 1651, due to a temporary defeat of the Cossacks, the new Treaty of Bila Tserkva was signed and it contained no more statements about the liquidation of the Greek-Catholic Church, which was allowed to reenter Chełm and Przemyśl.

Kolenda succeeded him as Administrator of the Greek-Catholic Church but not as Metropolitan, because due to the war it was not possible to convene the electoral synod as requested by Rome or to obtain the appointment from the King, who preferred not to displease the powerful Cossacks.

[5]: 233  To obtain some help for his Church, Kolenda sent in 1644 to Rome the bishop of Chełm, Jacob Souza, who succeeded in convincing the papacy to take a stand for the Ukrainian Greek Catholic Church, reaffirming its independence from the Latin episcopate, obtaining the appointment of Kolenda as Metropolitan, confirming the validity of ordinations made by Orthodox, and ruling about the Basilian Order.

[9] After the Truce of Andrusovo in 1667 the war ended and the situation of the Ukrainian Greek Catholic Church improved, even if it had to leave the town of Smolensk and the capital Kiev.
