One Church and Two Nations: a Uniquely Irish Phenomenon?
The Reformation in the sixteenth century brought with it the complex and—for contemporary religious and political groupings—unacceptable phenomenon of religious plurality. In the Middle Ages citizenship as an independent concept scarcely existed, and tacit assumptions about the function of Church-State relations rested on the view that all inhabitants of the polity were members of the Christian respublica. There were, of course, some specific, necessary, and therefore tolerable exceptions, such as Jews in many, but not in all countries. Heretics and infidels, who did not conform to these specifications, were therefore regarded as legitimate targets for repression, even for physical violence, in the complex machinery of the Inquisition and in the ideology of the crusades. The Reformation brought about a reversal of this monolithic thinking about the nature of the Christian polity. Faced with plurality of religious ideas and organizations, various solutions were attempted. The earliest, and that which was to have the most widespread and long-lasting effect in pre-Enlightenment and pre-Emancipation Europe, was that formulated in the Religious Peace of Augsburg (1555). Here the decree of cuius regio, ejus religio—with a deliberate retrospect to the Emperor Constantine—guaranteed the continuation of the medieval principle, whereby the good and loyal citizen was one who conformed in religious as well as political sentiment with the ruling authority.
