Oliver Bullough writes in a New Statesman article about evangelicals' influence on British politics:
The Archbishop of Canterbury, Justin Welby, has made repeated political interventions since his appointment. In March last year, just before he was formally elevated to the See, he lambasted a government attempt to cap welfare increases at 1 per cent a year. Since then, he has criticised energy companies and promised that the Church of England will drive the payday lender Wonga out of business (although, after the Church was discovered to have invested £80,000 in the company, he had to soften his rhetoric). In Rome, Pope Francis has been pushing a similar message.
[Labour’s] Ed Miliband and his party should not assume, however, that this means believers will necessarily follow the bishops in the polling booths. Research by Linda Woodhead of the University of Lancaster shows that most Christians who attend church don’t much care what their religious leaders think. Only one in 50 Anglicans, and one in 25 Catholics, takes guidance from church leaders in reaching moral judgements.
