From the Holy Father’s homily at Vespers on the Feast of the Conversion of Saint Paul, 25 January, the end of the Week of Prayer for Christian Unity:
I entrust to the intercession of St. Paul all of those who with their prayer and their work commit themselves to the cause of the unity of Christians. Even if we can at times have the impression that the road toward complete re-establishment of communion is still very long and full of obstacles, I invite everyone to renew their determination to continue, with courage and generosity, the unity willed by God, following St. Paul’s example, who, in the face of difficulties of every sort always maintained firm confidence in God, who brings his work to completion. After all, along this journey there are not lacking positive signs of a rediscovered fraternity and of a shared sense of responsibility before the great problems that afflict humanity. All of this is reason for joy and great hope and must encourage us to continue our commitment to arrive together at the final goal, knowing that our toil is not in vain in the Lord (cf. 1 Corinthians 15:58). Amen.
