Previous parts of this series have demonstrated the superiority of the biblical Christian system to the naturalist-uniformitarian system in providing metaphysical and epistemological frameworks for Earth history research. Following a logical progression towards deriving geologic models, the next step is the use of information from sources other than geology to constrain and direct model formulation. To begin the process, special revelation will be applied as a primary constraint. As the most reliable source of historical information, the Bible provides both general and specific constraints. General constraints include: Limited time; catastrophic process; an event-oriented perspective; and the possibility of a more complete geologic record than is recognized by uniformitarians. Specific constraints include the outline of historical events presented in the biblical text. Although many constraints from other disciplines (e.g., history, archeology) could be explored, a rigorous examination of these areas is beyond the scope of this paper.
