Ukraine

Religious developments

As social conditions among the Ukrainian population in Lithuania and Poland progressively deteriorated, so did the situation of the Ruthenian church. The Roman Catholic Church, steadily expanding eastward into Ukraine, enjoyed the support of the state and legal superiority over the Orthodox. External pressures and restrictions were accompanied by a serious internal decline in the Ruthenian church. From the mid-16th century, both Catholicism, newly reinvigorated by the Counter-Reformation and the arrival of Jesuits in Poland, and Protestantism (albeit temporarily) made inroads, especially among the Ruthenian nobility.

Attempts to revive the fortunes of the Ruthenian church gathered strength in the last decades of the 16th century. About 1580 Prince Konstantyn Ostrozky founded at Ostroh in Volhynia a cultural centre that included an academy and a printing press and attracted leading scholars of the day; among its major achievements was the publication of the first complete text of the Bible in Slavonic. Lay brotherhoods, established by burghers in Lviv and other cities, maintained churches, supported schools and printing presses, and promoted charitable activities. The brotherhoods were frequently in conflict with the Orthodox hierarchy, however, on questions of authority over their institutions and clerical reforms.

Religious developments took a radical turn in 1596 when, at a synod in Brest, the Kievan metropolitan and the majority of bishops signed an act of union with Rome. By this act the Ruthenian church recognized papal primacy but retained the Eastern rite and the Slavonic liturgical language, as well as its administrative autonomy and traditional discipline, including a married clergy.

This so-called Uniate church was unsuccessful in gaining the legal equality with the Latin church foreseen by the agreement. Nor was it able to stem the process of Polonization and Latinization of the nobility. At the same time, the Union of Brest-Litovsk caused a deep split in the Ruthenian church and society. This was reflected in a sizable polemical literature, struggles over the control of bishoprics and church properties that intensified after the restoration of an Orthodox hierarchy in 1620, and numerous acts of violence. Efforts to heal the breach in the 1620s and ’30s were ultimately fruitless. (See also Eastern Rite church.)
