In a fitful light

"To live in Rome is to be involved in a rich conversation of twenty-seven centuries, drawing in people from every part of the world and showing no sign of abating. It is called the Eternal City but there is none more time-bound: all the past generations can still get a hearing; their ancient monuments rise like enfeebled fingers to make their points. Christians have always been glad to join in, because the doctrine of the Trinity tells us that our God is a conversation."
