Finally, I would like to note that tomorrow the traditional Week of Prayer for Christian Unity begins. Every year it constitutes, for believers in Christ, a propitious time to revive the ecumenical spirit, to meet each other, to get to know each other, to pray and reflect together. The biblical theme, taken from the Gospel of St. Luke, echoes the words of the risen Jesus to the apostles: “You are witnesses of these things” (Luke 24:48). Our proclamation of the Gospel of Jesus will be much more credible and effective the more that we are united in his love, as true brothers. Thus, I invite parishes, religious communities, ecclesial movements and associations to pray unceasingly, in a special way during Eucharistic Celebrations, for the complete unity of Christians.
