title: Joint Declaration of Pope Francis and Patriarch Kirill
context: The Joint Declaration of Pope Francis and Patriarch Kirill, also known as the Havana Declaration, was issued following the first meeting in February 2016 between Pope Francis, who as the Bishop of Rome is the pontiff of the Catholic Church, and Patriarch Kirill of Moscow, Patriarch of Moscow and all Rus', Patriarch of the Russian Orthodox Church (ROC), the largest of the Eastern Orthodox churches. This was the first time leaders of the Roman Church and the Moscow Patriarchate had met. While the meeting was also seen as a symbolic moment in the history of relations between the Catholic Church and the Orthodox churches as a community, which had split in the Great Schism of 1054, centuries before the Moscow Patriarchate was constituted, it was not expected to lead to any immediate rapprochement between them.[1]
