Wait a sec. The head (after the Queen) of the Church of England is also on the parliamentary banking commission? Isn’t there some rule about serving God and Mammon?
The parliamentary banking commission isnt neccesarily on the bankers side, as you might tell from Welby's comments. Besides, he took a substantial pay cut when he moved from oil executive to clergyman. I think more than most he can say he gave up mammon for God.
