Mr Williams undoubtedly wants to do good in the world. And he is far from being a stupid man; he is considered to be a profound thinker and theologian. But it took Iain Duncan Smith, in the striking article he wrote for this paper last week, to use without embarrassment the Biblical figure of Joseph to illustrate one of the key antidotes to permanent poverty — the committed father.
The fact is that what Mr Duncan Smith is doing embodies Christian conscience in a way that appears completely to elude the leader of the Anglican communion.
When a politician boldly links morality, religion and compassion while a religious leader can only spout Left-wing cliches, a society’s foundations have become shaky indeed.
