MADRID, Spain (CNS) -- Communication is the best way to achieve peace, a top Vatican official told Jews, Christians and Muslims. "The Holy Father believes that a dialogue founded on love and truth among the followers of Judaism, Christianity and Islam is the best way to help turn all peoples of the earth into one single family," said Cardinal Jean-Louis Tauran, president of the Pontifical Council for Interreligious Dialogue. He spoke July 18 during closing remarks at the World Conference on Dialogue, a three-day meeting initiated by Saudi Arabian King Abdullah Aziz. "Jews, Christians and Muslims show that religions are not a source of tension. On the contrary, they have a tremendous positive potential for the humanization of the whole of society," Cardinal Tauran said, adding later that "all those who search for God have equal dignity." Representatives of other monotheistic religions, such as Buddhism, Hinduism and Shintoism, also attended the event.
