Athenagoras I

Athenagoras I was the Ecumenical Patriarch of Constantinople from 1948 until his death in 1972. He is best known for his efforts to promote dialogue and unity between the Eastern Orthodox Church and the Roman Catholic Church, notably through his historic meeting with Pope Paul VI in 1965, which marked a significant step towards reconciliation after centuries of division. His leadership emphasized the importance of theological dialogue and the need for mutual understanding among Christian denominations.
