In these pages, Andrea Riccardi reflects on the need to create a culture of peace, a spiritual and social movement that puts peace at the center of public concerns and politics. It is up to each of us to become an artisan of peace: our choice lies at the beginning of peace building. Not turning away means knowing, becoming informed, following events, standing in solidarity with those suffering from war, remembering them in prayer. A living public opinion can influence and change national events and international policies. It can hold back or prevent war, and open avenues for peace.
