Pope Francis and the grand imam of Southeast Asia’s largest mosque vowed Thursday to fight religiously inspired violence and protect the environment, issuing a joint call for interfaith friendship and common cause at the heart of Francis’ visit to Indonesia.

In the morning event at Jakarta’s iconic Istiqlal Mosque, Francis presided over an interreligious gathering rich with symbolic meaning and personal touches. Present were representatives of the six religions that are officially recognized in Indonesia: Islam, Buddhism, Confucianism, Hinduism, Catholicism and Protestantism.
