In the immediate aftermath of ‘9/11’, it took very little for the axiom that adherents of evangelical Christianity and reformist Islam inhabit discrepant, permanently warring publics to solidify. With the very air laden with ‘the clash of civilizations’, the dominant narrative quickly became one of mutual antagonism, in which both religions were positioned as irreconcilably foundational in major global conflicts. As is often the case in such moments of heated contention, it was easy to overlook the counterintuitive fact that, in various parts of the world, especially in those communities where adherents of both faiths have lived in close proximity, there has always been a direct sharing and transfer of experiences in religious practices and evangelizing stratagems. Such ‘spiritual economies’ (cf. Rudnyckyj 2010) do not imply that theological differences are erased; they suggest, rather, that competing faiths, in their attempts to expand and preserve themselves, frequently cross boundaries to appropriate the other's devotional and conversionary strategies.
