Alvin Plantinga The Reformed Objection to Natural Theology
Pages 10

Suppose we think of natural theology as theattempt to prove or demonstrate the existence of God. This enterprise has a long and impressive history-a history stretching back to the dawn of Christendom and boasting among its adherents many of the truly great thinkers of the Western world. Chief among these is Thomas Aquinas, whose work, I think, is the natural starting point for Christian philosophical reflection, Protestant as well as Catholic. Here we Protestants must be, in Ralph McInerny’s immortal phrase, Peeping Thomists. Recently-since the time of Kant, perhaps-the tradition of natural theology has not been as overwhelming as it once was: yet it continues to have able defenders both within and without officially Catholic philosophy.1
