The Relation between reason and faith in Summa Theologiae

I will try to show how Thomas Aquinas, via distinction of natural theology from divine revelation, has provided a fundamental basis for the originality of realm of reason, viz. Philosophy and natural sciences instead of realm of faith; and this is the beginning of the modern world. This approach to understanding Summa Theologiae is distinct from Gilson's writings based on which reason and faith according to Thoma's thought are in harmony. He understands Thomism as the perpetual wisdom, but I will try to explain a new consideration about his thought; the reason is fundamental and limited in Thoma's theological writings.
