The week of prayer for Christian unity culminates with the feast of the conversion of St Paul on January 25th. St Paul is probably the most energetic and tireless worker for unity whom the Church has ever known. Many passages in St Paul's epistles are devoted to the theme of unity and the epistles themselves bear witness to his work for it.

But when we read these epistles we are struck immediately by St Paul's tremendous sense of the power of intercession and its importance in the life of Christians. Thus he writes to the Romans:

'For God is my witness … that without ceasing I make mention of you always in my prayers’ (Rom. i, 9).
