“While sometimes characterized as the ‘Age of Faith,’ the sixteenth century actually had its share of religious skeptics. When John Calvin encountered these men, he often found it necessary to provide arguments that might ‘shut the mouth of the obstreperous.’ In other words, he was not opposed to engaging in subtle arguments. At the same time, though, it is instructive to consider his views of the limits of such argumentation. Natural theology is useful to refute the arguments of unbelievers and it may be useful to convince some people of the existence of a God, but we must be mindful lest we forget that natural theology has definite limits. It can never provide saving knowledge.”
