Is Catholic-Orthodox reunification inevitable under Bartholomew I?

Ecumenical Patriarch Bartholomew I stated in November 2019 that he views the reunification of the Eastern Orthodox and Catholic churches as inevitable. This perspective builds upon decades of improving relations, including the lifting of mutual excommunications in 1965 by Pope Paul VI and Patriarch Athenagoras I. However, intra-Orthodox divisions and distinct theological views continue to complicate the path toward full Christian unity.

What we know

• In November 2019, Ecumenical Patriarch Bartholomew I stated that the reunification of the Eastern Orthodox and Catholic churches is inevitable in his view. [3]
• Relations between the Catholic and Eastern Orthodox churches began to warm significantly following the Second Vatican Council and the 1965 lifting of the mutual excommunications of 1054. [3]
• Bartholomew I serves as the primus inter pares and the spiritual leader of Eastern Orthodox Christianity worldwide as the 270th successor of the Apostolic See of St. Andrew. [2]
• Bartholomew I's tenure has involved active intra-Christian and inter-religious dialogue, including formal visits to Roman Catholic, Old Catholic, Oriental Orthodox, and Muslim leaders. [2]

Still open

• It remains unresolved whether the broader Eastern Orthodox communion will accept or follow through on Bartholomew I's vision for eventual reunification given existing intra-Orthodox tensions like the Moscow-Constantinople schism.
