The pope made the call during a speech at the Jesuit-run theology university in Naples, AP reported.

It follows his outreach this year to the Muslim world with the signing of a joint statement with the imam of Cairo’s Al Azhar, the seat of Sunni learning, establishing the relationship between Catholics and Muslims as brothers, with a common mission to promote peace.

In his speech, Francis said dialogue and partnership with the Muslim world is necessary “to build a peaceful existence, even when there are the troublesome episodes by fanatic enemies of dialogue.”

Catholic theology students must learn the culture, language and way of thinking of Jews and Muslims “to better understand and live out our relationship,” he said.
