Pope Francis has said Catholics must speak their minds and not be afraid to offend him, during his address to the opening session of the family synod at the Vatican this morning. Speaking to the gathered bishops he said the faithful must not keep things back just because they might be worried "what will the Pope think", according to Catholic News Service. "Speak clearly. Don't tell anyone, 'you can't say that'," he added. Pope Francis went on to say that "the spirit of collegiality is to speak boldly and to listen with humility" and he also welcomed the lay men and women present at the synod. "You enrich our spirit of synodality," he told them. During the two-week synod summaries of each session will be published by the Holy See press office at the end of each day.
