The Ecumenical Office has as its main function the task of providing information, stimulating interest and coordinating ecumenical activities on the archdiocese, metropolis and parish levels. It adheres to the principle that Orthodoxy and Orthodox ecumenism must always speak the truth, never compromising the integrity and purity of Orthodox teachings, but always respecting the sincerity of the religious convictions and spiritual sensitivities of others.
