In many North American Protestant circles, especially those with Baptist or Free Church roots, the notion of the total separation of church and state is presented as the ideal to be attained in all church and state relations. We are told that the state should have no legislative power to ordain anything in relation to church doctrine or practice, and that the church should be entirely excluded from all political, secular, or state actions. In this paper, we are going to suggest that such an approach to church–state relations (even though some might think that it flows from or is necessary for democracy) is, in fact, impossible in a true democracy. We will first consider the nature of the church and the state, and present three principles that Maritain suggests are first principles in this debate. We will then look at the classical notion of the “Citizen”. We will conclude by arguing that based upon the nature of a citizen, of the church, and of the state, a strict separation of church and state is, in fact, impossible.
