All religion aside, this visit was very important (maybe more so than the UK visit by Pope JPII) because this is a state visit. As the head of a state, he is the guest of another head of state (The Queen). Religion infused, this is a head of state/head of religion who is inviting another head of state/head of religion to her country. As you are from Scotland, from someone else within the worldwide commonwealth, it is always week long televised news about dignitaries coming to visit (When we had Charles and Camila here recently, it was a huge deal--not to mention when the Queen comes).
The thing is, the majority of people didn't agree that it should have been a State visit. If the head of a church wants to come over, fine, but that church should pay for it.
He came as a religious leader, that much was clear. His comments were of a religious leader. It doesn't matter what title they put on the visit. One of the first things he said in the linked not believing in God with Nazism, I can't speak for others, but I don't want that in my country.
B16: Of course, the character of a state visit focuses attention on the converging interests of politics and religion. Politics is essentially designed to ensure justice and with justice, freedom, but justice is a moral value, a religious value, and so faith, the proclamation of the Gospel connects with politics in justice and here common interests are also born.
He came as the pope, that's all any one sees his as. Of course, you wouldn't agree, but it was clear that the majority of the country didn't want him to come over at all - only if you were Catholic. That's all there is to say on it.
