The three essays in this section are an attempt to bring the insights of two schools of thought to bear on certain fundamental questions of ecclesiology. The two schools, which overlap one another to a large extent, are Vantillian presuppositionalism and Christian reconstructionism. Presuppositionalists such as Van Til himself, Norman Shepherd, and John Frame have concentrated on philosophical and dogmatic issues, while Vern S. Poythress has extended the school of thought to the areas of hermeneutics and exegesis. Reconstructionists such as R. J. Rushdoony and Gary North have concentrated on socio-political issues. To my knowledge, these efforts constitute the first time anyone has attempted in print to bring these insights to bear on ecclesiological questions. Of necessity, therefore, these essays are somewhat tentative, and are offered to the church at large as springboards for reflection, and certainly not as the last word on the subject.
