There is something simple and dead good about a new pope beginning his pontificate by saying “Good evening” to the world. Nothing pious or 'deep', but simply human. I loved it.

It was quite funny watching the instant expertise all over the media from people who, ten minutes earlier, didn't know the Argentinian bishop from the Argentinian centre forward. Within minutes people were making instant judgements on him, his record, his character, his likely priorities. Utterly ridiculous, really. As I said on BBC Radio 5Live (!), we look for the 'iconography' of his appointment whilst ignoring the fact that the new man will have to come at the new role/challenges with a completely fresh approach. The past might give hints, but it won't necessarily set out a predictable future.

That said, however, Pope Francis might well bring an outside eye to the Curia, a South American perspective on both faith and social priorities, a fresh (and credible) critique to the world's dominant cultural obsessions, and a realignment of the Church's priorities with those of Jesus. Who knows if there will be any radical change – probably not in terms of the tough stuff around culturally. Probably both continuity and discontinuity – a bit obvious, really. We shall see.

To do any of this at the age of 76 is a tough call, isn't it? He will need the prayers of those who want him to grasp the nettles of change, and he will covet the encouragement of those who know just how hard it is to bring about change in any institution or organisation.

Anyway, Francis 1 started with human informality. He then asked people to pray for him before he blessed them. He then led people in the prayer that Jesus taught his friends – not as a mantra of pious wishful thinking, but as a manifesto for responsibility and change. As the noise rose around him he stood motionless – a place of rooted calm while the sea raged around him. A good external symbol that might (must?) indicate the internal centredness of the man.

Keep it simple, Francis. Please.
