Abstract: | This study argues that the eighteenth-century political philosophyof federalism found its roots in covenant theology of earlyReformed Protestantism in Zurich. It contends that there wasa progression covenant or federal thought from the first publishedarticulation of the theological covenant by Bullinger in 1534,through the use of the covenant notion in defense of tyrannicideby Philippe Mornay, to Johannes Althusius's political philosophyof federalism, as well as the political theories Thomas Hobbesand John Locke, to the Declaration of Independence and the Constitutionof the United States. These different faces or variations offederalism shared several common elements over the 250-yearspan. |
