In the fourth of a series exploring episcopal life, auxiliary bishop John Sherrington finds the challenges of his calling an opportunity for growth.

When I went up to Queens’ College, Cambridge, to read mathematics in 1977, I had no inkling of a vocation. But I went to Fisher House for Mass every Sunday – Fr Maurice Couve de Murville was the chaplain – and my curiosity about the faith grew. I remember going to Mowbrays to find books to help deepen my understanding of theology – I bought one on Creation and evolution, and one on faith and revelation. I also started to read the homilies of Archbishop Óscar Romero. They brought my faith to life.
