 The seventeenth and early eighteenth century in England saw a rationalist treatment of theology that spanned many competing groups from the Latitudinarians to the Dissenters to the Deists. Samuel Hefelbower in The Relation of John Locke to English Deism remarks that among the progressives—theologians, philosophers and deists—all accepted a rationalistic religion. The question then becomes what exactly is the role of reason vis à vis revelation. The discussion of the relation of reason to revelation goes back at least to Albertus Magnus and Thomas Aquinas—that is to the scholastic authorities. Albert held that reason has a role to play in religion, but there are questions where philosophy has no final answer and revelation must decide. Revelation is above reason but not contrary to it. Thomas has a similar position (Hefelbower 1918: 47). Locke holds that reason is responsible for determining what counts as a genuine revelation. Locke also holds the view that there is revelation that tells us about things above reason but not contrary to it.
