The movement aimed to repair the divide between Eastern and Western Christianity is known as the ecumenical movement or the Eastern Orthodox Church's reconciliation efforts with the Catholic Church. Historically, the Great Schism of 1054 resulted in a formal separation between the Roman Catholic Church in the West and the Eastern Orthodox Church in the East, driven by theological disagreements and cultural differences. The ecumenical movement seeks to foster dialogue and mutual understanding, encouraging cooperation on social issues, theological discussions, and shared values among different Christian denominations. Its long-term goal is to promote unity among Christian believers while respecting the distinct heritage of each tradition.
