Stretchy definitions of ‘Nationalism’ can be a useful political tool, says Nick Spencer, senior fellow at Theos Think Tank. People can give a ‘thin’ definition while their actions suggest something ‘thicker’ and more like 19th century definitions.

Nick gives us a vision of Christian engagement in politics that navigates through the tricky waters of coercion vs. persuasion and offers some much-needed wisdom in the conversation.
