1. He forged a career in the oil industry before ordination. This is unusual among Bishops, who are mostly cradle clergy. While that too has its advantages, it means they have little direct experience of leadership and management outside the church.
2. He has risen through the ranks of the clergy, as we might expect, but his ministry has been of the hands-on leadership type, not in the backroom bureaucracy or the corridors of power. His time as the director of Coventry's ministry of reconciliation is a particular highlight in a CV which is is not really done justice by the Diocese of Durham's bigging up of how many people he gets to come to church.
3. Nevertheless, we can see that he is an evangelical who understands the importance of local mission but also works comfortably within inherited church structures. Always Hope approves of people like that.
4. He has a successful record of leadership, another much under-rated asset in Bishops.
5. He appears to be quite brainy, which will help.
Good news for the Diocese of Durham, I reckon. Bishop Welby will be well worth keeping an eye on.
UPDATE: 9th November 2012. Since he is now to be the next Archbishop of Canterbury, I've written a new post by way of an update.
