Since the local Orthodox Church of Ukraine received the Tomos of Autocephaly, Patriarch Bartholomew has visited all of them, the visit of Pope Francis is expected in the near future, and religious and ecumenical themes have become one of the top in the press. That is why there is a need to analyze its development and coverage in various media. The article analyzes the main stages of the ecumenical movement: from the origins that led to current issues of inter-church understanding in Europe to historical circumstances that created the preconditions for signing documents that were organized and enabled quality ecumenical dialogue. Emphasis should be placed on the functioning of the ecumenical movement in Protestant communities, the Catholic and Orthodox Churches. The peculiarities of the functioning of the Ecumenical Concept of the UGCC, its coverage in the press, as well as the coverage of this document in 2021, given the need for updating, are considered. The ecumenical concept of the UGCC (updated and preliminary) has found its response in major thematic online resources. After receiving Tomos, the PCU introduced its communication strategy with other denominations more actively. Therefore, the preconditions for the establishment and development of the Commission on Inter-Christian Dialogue at the PCU and its presentation in the press were analyzed. The focus is on specific agreements and memoranda signed in the twentieth century that illustrate the progress of ecumenical dialogue in religious Christian communities. The article also presents ecumenical publications in the Ukrainian press, which have their own chronological legacy, as they are based on the journalistic experience of past generations. It is emphasized that ecumenism is not just a world church movement, but a real instrument which these days is influencing religious life, as well as is being constantly renewed, changed. This is embodied especially in the updated Ecumenical Concept of the UGCC, which is also analyzed in the article. The greatest development of the ecumenical movement took place in the twentieth century. It is the lever that helps the Christian religious society seek peaceful dialogue, get rid of the historical wounds of the past, while respecting each other's denominational individuality.
