Last November, members of a Sunni militia in Syria went to a hospital, found a patient whom they took to be a Shi‘ite, and beheaded him. Showing a typical jihadi concern for public relations, they then made a video about the incident in order to get their message out, saying of the Shi‘ites: “They will come and rape the men before the women, that’s what these infidels will do. They will rape the men before the women. God make us victorious over them.” As it turned out, their video proved a bit of an embarrassment: it emerged that the man they beheaded was not in fact a Shi‘ite — but as jihadis will tell you, and not only jihadis, these things happen.

In Simon Critchley’s Wildean confraternity or consorority of the faithless, faith is a commitment, a proclamation of fidelity to an infinite ethical demand which enacts a new form of subjectivity. As such, faith is not related to belief in the existence of God but to an experience that is shared by agnostics, atheists and theists alike. Faith, we might say, is a/theistic, cutting across such distinctions.
