Organised religion is an eternally frustrating phenomenon. Spouting bigotry, spreading ignorance and fermenting irrational hatreds, it’s grown rich at the expense of millions of earnest on-the-ground believers. On the other hand, it can occasionally shock by actually doing what it says on the tin, preaching love and compassion in the public realm. Since the establishment is less wary of vicars than shouty socialists, some of the more radical commentary that manages to poke its way into the mainstream comes from religious figures. Ex-Archbishop of Canterbury Rowan Williams somehow managed to combine being one of the most prominent critics of the post-crisis socioeconomic status quo with heading one of the country’s most conservative institutions. Archbishop of York John Sentamu is a more difficult figure – funny, charismatic, passionately for social justice, but, at the same time, still holding firm to the Church’s standard Neanderthal view on homosexuality and gay marriage. Here, though, in a brief, brilliantly clear bit of writing, he makes the case for the Living Wage.
