Well there was popery anyway
The ecumenical service at Westminster Abbey has just concluded. There was some very beautiful singing, including Duruflé's Ubi Caritas, the Pope and the Archbishop Canterbury delivered addresses, and venerated the shrine of St Edward.
There was a rather noisy gathering of Protestants outside beforehand. Fortunately there were plenty of Catholics mixed up among them so the boos were mostly drowned out by the cheers. Rather a pity to have a protest like that but I don't expect it bothered the Pope too much. A French journalist who was standing next to me was completely baffled by it.
