On December 7-8, 2022 at 4 p.m. Kyiv time (UTC/GMT +2 hours), the Institute of Ecumenical Studies of the Ukrainian Catholic University invites you to the International Academic Conference on the topic: "The Eastern Catholic Churches: Can They Speak with One Voice?"

Venue: Conference Hall of the UCU Faculty of Philosophy and Theology, str. Khutorivka 35a, with the possibility of online joining via ZOOM.

Working languages: Ukrainian and English with simultaneous translation.

The work will focus on exploring what the various Eastern Catholic Churches have in common that allows them to speak with one voice, and what are the main obstacles that make this task difficult? Our goal was to gather speakers with a solid academic background, representatives of various Eastern Catholic Churches and Liturgical Traditions.

On the first day, December 7, we will consider this question from a historical perspective.
