The article analyzes the issue of Petrine Primacy putting in evidence the need to find a common basis of New Testament for its discussion, as well as the last steps of the bilateral dialogues between the Catholic Church and the Orthodox, Anglican and Lutheran churches. In this regard we seek to realize the movement to strengthen dialogue that sometimes reveals advances and sometimes old difficulties. We emphasize the role of Pope John Paul II as a promoter of dialogue on the exercise of Petrine ministry of Pope, through his invitation to all pastors and theologians - catholics and from other churches - to find that new forms of exercising the primacy that are shared by all. Finally, there is space for the resignation of Pope Benedict XVI - read in positive terms by the ecumenical movement - and the election of Pope Francis that, since the first public appearance as Pope, calls himself Bishop of Rome, ecumenical title of great value between churches.
