Whilst our take on theology may be different, the Archbishop is to be respected and even applauded for his stand: "Later today I will stand waist-high in an open-air pool in the middle of York city centre......". I'd be interested to see the response to his call.
And Pope Benedict's Urbis et Orbi speech summary here
I suspect that the report, of necessity, was short on information. It seems, from that, that the Pope was just echoing what many people in the world
are saying. End wars, end oppression, and fix poverty. If he repeated the same message in all 63 languages, which is a nice, but redundant, touch, he
would have had little time to address anything meaningful in his message anyway.
Not that it matters, but, to me, the Archbishop of York's message was more practical.
