Archbishop Peter Smith, not previously known for his expertise in economics, informs us that he finds “ludicrous” an opinion held by the G20, the IMF, the Institute for Fiscal Studies, the London School of Economics, the Governor of the Bank of England and most economists (News Briefing, 28 May).

What, I wonder, would these institutions think of the archbishop’s opinions on the Trinity?
