In a landmark event bridging centuries of religious history, King Charles III and Pope Leo XIV will pray together at a church service in the Vatican’s Sistine Chapel next week. This unprecedented moment marks the first time a British monarch and a pontiff have shared such a spiritual gathering since the 16th-century Reformation. The service, held under Michelangelo’s iconic ceiling, will unite clergy and choirs from both the Roman Catholic Church and the Church of England, of which King Charles is the supreme governor. The visit, scheduled for October 22 and 23, is being hailed as a powerful symbol of reconciliation between the two faiths. The King and Queen Camilla will also meet Pope Leo, the first US-born pontiff, and senior Vatican officials, further strengthening ties between the UK and the Catholic Church. The ecumenical service will focus on environmental protection, reflecting King Charles’s longstanding commitment to environmental causes. Additionally, the King will attend a service at St. Paul’s Outside the Walls, a church historically linked to the English monarchy, where he will receive an honorary spiritual title as a “royal confrater.” This visit underscores the King’s dedication to fostering interfaith dialogue and unity.
