Pope Francis delivers his message on the occasion of an audience with participants of Rome's diocese convention in St. Peter's Square, at the Vatican, Sunday, June 14, 2015. Francis engaged in some self-promotion during his weekly blessing, alerting the thousands of people in St. Peter's Square that his first solo encyclical is coming out on Thursday and inviting them to pay attention to environmental degradation around them.
