This is a time to be both politically and practically subversive in the face of a growing political consensus that is hurting the most vulnerable, says Jonathan Bartley. All of the main parties in the UK, including Labour, support the cut in housing benefit. Labour has said that it would not reverse it - or, indeed, most of the other welfare reforms - should it gain power at the next election. In the face of such a negative consensus, new social housing could become a central weapon in the Churches' fight to protect the poorest.
