In more than 20% of countries, a single religion is recognized in the constitution. This article argues that there are good reasons for opposing such ‘mono-recognition’ as it fails to show due concern to members of constitutionally unrecognized religions. Yet rather than opting for disestablishment as Sweden did in 2000, I show that there may be a better alternative in many cases: To constitutionally recognize a variety of religions. After distinguishing synchronic forms of plural recognition whereby multiple religions are constitutionally (...) recognized simultaneously from diachronic forms whereby state religions are rotated, I defend the latter option. On this approach, a multi-religious state might have Catholicism as the state religion during the first part of the year, then Islam, then Judaism, and so on, whereby I argue that there ought to be differences in the amount of time that religions are recognized depending on differences in the strength of their claims to constitutional recognition. Besides being fairer than mono-recognition and synchronic plural recognition, I show that when some religious groups are marginalized, diachronic plural recognition has significant advantages over non-recognition of any religion as constitutionally recognizing these groups’ religions sends valuable signals that their members belong to society.
