During his visit to Indonesia, Pope Francis met with Grand Imam Nasaruddin Umar at the Istiqlal Mosque, where they signed a joint declaration aimed at combating climate change and religious intolerance. The declaration urges Catholics and Muslims to unite in their efforts to advocate for environmental protection and to address issues of violence justified by religion. Francis emphasized the mosque as a 'great gift' and called for interfaith solidarity, highlighting the importance of coexistence among different beliefs. He also celebrated a Mass attended by over 100,000 people, underscoring the significance of his message in a country with the world's largest Muslim population. The visit is part of Francis's broader 11-day tour of the Asia Pacific region, focusing on fostering dialogue and understanding between faiths. Despite constitutional guarantees of religious freedom in Indonesia, challenges remain, with incidents of intolerance reported in recent years.
