The thesis of this study is that Geerhardus Vos" biblical-theological method should be viewed as a post-Enlightenment continuation of the pre-critical federal theology of seventeenth-century Reformed orthodoxy. Vos wrote in the context of the liberalism of the late nineteenth and early twentieth centuries. His biblical-theological methodology was largely a resuscitation of the federal theology of seventeenth-century Reformed orthodoxy adapted to the times in which it was written.
