My baptismal certificate gives the time and place – as an infant, in the mid-20th century, in a parish of the Church of England, at the hands of the vicar. But how was I to understand this baptism? I could think of it as baptism into the established church of a particular state and nation. Or because it was a baptism into Christ, I could think of it as being into a Church that is universal, and that has no essential connection either to England or to the British state. What did the fact of being English or being British have to do with my being Christian?
