Christians have a mission to convert all Muslims, according to one of Pope Francis's senior aides. Cardinal Kurt Koch, who leads ecumenical relations for the Vatican, made the comments at an interfaith meeting held by Cambridge University's Woolf Institute. Cardinal Koch also said that Christians should not try and convert Jews and should view Judaism as a "mother". "We have a mission to convert all non-Christian religions' people [except] Judaism," he said, before reportedly adding that this extended to jihadis responsible for persecuting Christians in the Middle East. The cardinal also urged Christians to view Judaism as a "mother" and said Christainity and Judaism shared a special relationship. "It is very clear that we can speak about three Abrahamic religions but we cannot deny that the view of Abraham in Jewish and the Christian tradition and the Islamic tradition is not the same," he said. "In this sense we have only with Jewish people this unique relationship that we do not have with Islam."
