Religion as Liberal Politics

Abstract

US and UK courts define religion as a belief system dealing with existential concerns, which is separable from politics, and need not be theistic. Where does this concept of religion come from? Some scholars trace it to the advent of the Protestant Reformation when religion became a matter of competing theological propositions. My analysis of both John Calvin and Roger Williams shows that those Protestant thinkers emphasized the view that religion is essentially a belief system. However, Protestantism cannot explain all of the features of the US and UK concept of religion. It is because of the liberal belief in individual rights and in popular sovereignty that early liberals like Roger Williams and contemporary courts embrace the separability of religion from politics. These courts also reject the view that religion is necessarily theistic given their liberal commitment to treating citizens that subscribe to certain non-theistic ideologies as equal citizens to citizens with theistic ideologies.
