How did Pope John Paul II work to improve relations with other Christian churches?

Pope John Paul II actively pursued Christian ecumenism, building upon the spirit of the Second Vatican Council to foster greater unity among Christian denominations. His efforts included:12

• Ecumenical Outreach: He authored the encyclical Ut unum sint (1995), which reviewed decades of ecumenical progress and invited non-Catholic churches to engage in a dialogue regarding the role of the papacy in world Christianity.3
• Symbolic Visits: He conducted historic visits to various non-Catholic sites, including Canterbury Cathedral in England and Lutheran churches in Germany and Sweden.3
• Eastern Orthodox Relations: He sought to mend the long-standing rift with the Eastern Orthodox Church, notably traveling to Turkey in 1979 to meet with the titular head of the church. While he visited several nations of the former Soviet Union to advance these ties, full reconciliation remained challenging, particularly with the Russian Orthodox Church.43

These initiatives reflected his commitment to dialogue and reconciliation, which he extended to non-Christian faiths as well.1
