As vicar of St Martin in the Fields, Nicholas Holtam reflects on important characteristics of parish ministry and mission. Like Trafalgar Square, it should be open to the world, not inward-looking; it should be a place of prayer and it should be open to the poorest. This was the vision which shaped Dick Sheppard's work at St Martins - as the 'ever-open door'.

In the traditions of St Martins, Nicholas Holtam broadcasts regularly, runs the largest homeless project in Britain, relates to Trafalgar Square with its people from all over the world, and its demonstrations on major issues.
