Welby really is interested in banking, isn't he ? As well as pontificating, and bidding for RBS branches (can the Coop be far behind ?) the archbishop is leading the CoE into the credit union business. He intends to "compete Wonga out of business": a very practical churchman indeed.
People may snipe: but his instinct isn't wrong at all. At the political 'surgery' I assist with, when (as happens from time to time) a gaunt figure shambles in having not eaten in three days because their benefits have been discontinued after a conviction for benefit fraud, the principle institutions one can refer them to are the churches: the alternative is a self-referral to prison. It might once have been the workhouse, but not today: and civic society has to draw a line somewhere.
Wonga is, of course, de jure an entirely legitimate business. But it's a symptom of a pretty depressing state of affairs: and at the other end of the spectrum it represents are some very nasty 'institutions' of last resort: loan-sharking, prostitution, crime ...
Welby will doubtless encounter all manner of sniping and practical problems (he already has one awkward little local difficulty to fix). But the CoE still has a mighty asset base, and if he uses it cleverly (have a word with Prince Charles ...) he might actually do some real good. The Catholics, Mosques and temples - all of which have their own practical heritages - may not be far behind.
