The Roman Catholic Church is very hospitable to her ecumenical guests, and we were seated close to the altar in St Peter's Square.
In his moving homily the Pope did not once refer to himself as the Pope but as the "Bishop of Rome". He has done this consistently since his election and I think he may be setting down a marker for a fresh understanding of the place of the Roman Primacy in the Church, which may be significant for Anglicans. He also stood at a lectern to deliver the homily and preached without his mitre. He spoke from the heart about the Church needing to care for and serve the world, all people and even all creation (a Franciscan theme) with tenderness and love. He emphasised the priority we must give to the needs of the poor. From the crowd's response of spontaneous applause to these remarks he will have received a strong affirmation of this emphasis he clearly wants to place in his ministry.
I also enjoyed listening to his Italian spoken with the soft, sing-song accent of a native Spanish speaker from Buenos Aires!
