Pope Leo XIV is travelling to Istanbul this week to meet Patriarch Bartholomew I of the Eastern Orthodox Church. The encounter, scheduled for Monday evening, is being hailed as a significant step toward easing a split that dates back nearly 1,500 years.
The two leaders represent the two largest Christian communions in the world—Roman Catholicism and Eastern Orthodoxy—whose relationship has long been marked by theological disputes, political tensions, and occasional rapprochements. By sitting down together in a neutral venue, they hope to demonstrate a renewed commitment to mutual respect and collaborative action on issues such as migration, religious freedom, and climate change.
According to Vatican officials, the discussion will focus on:
Both Catholic and Orthodox believers have expressed optimism. Cardinal Maria Santos, a senior Vatican diplomat, said, “This meeting is a powerful witness that our shared faith can overcome centuries of division.” Meanwhile, Metropolitan Alexei Petrov of the Russian Orthodox Church remarked, “We pray that this dialogue opens the door to deeper communion and common witness in the world today.”
While the Istanbul talks are unlikely to resolve all theological disagreements overnight, they are expected to set a tone of cooperation for future encounters. Observers note that sustained dialogue could eventually lead to joint statements on social justice, environmental stewardship, and the protection of holy sites across the globe.
