I thought it appropriate to post authoritative work St. Thomas Aquinas writings. If nothing else they should be referred to before making our own personal interpretation and what the good Doctor did or did not say or what he meant and did not mean.

Endnotes
Extracts of the preface follow:
His whole life, all his intelligence, all his forces, were bent to the service of the Christian faith, both in his doctrinal battles and in the serenity of contemplation. Justification of this statement appears in the way he conceived his vocation as teacher. You find therein an ascending gradation which arouses admiration.
1.Whereas on the one hand he fully recognizes all that is excellent, from the philosophical standpoint, in the teaching and method of Aristotle, he shows, on the other hand, against the Averroists, that reason can prove nothing against the faith. This latter task he accomplished by demonstrating against them from philosophy itself, that God’s creative act is free, that creation need not be ab aeterno, that man’s will is free, that the human soul is characterized by personal immortality.
3. He shows that philosophy deserves to be studied, both for its own sake, and also to establish, by arguments drawn simply from reason, that the praeambula fidei are attainable by the natural force of human intelligence.
4. Theology must rather, he goes on to show, be studied as a branch of knowledge, which establishes scientifically a system of doctrine with objectivity and universal validity, a synthesis that harmonizes supernatural truths with the truths of the natural order. Theology is thus conceived as a science, in the Aristotelian sense of the word, a science of the truths of faith. [5].
5. This position granted, it follows that reason must subserve faith in its work of analyzing the concepts and deepening the understanding of revealed truths, of showing that many of these truths are subordinated to the articles of faith which are primary, and of deducing the consequences contained virtually in the truths made known by revelation.
7. Further, this conception of theology does not in any way lower Christian faith from its elevation. For, as the saint teaches, the source of theology is contemplation, [7] that is, infused faith, vivified, not only by charity, but also by the gifts of knowledge, understanding, and wisdom, gifts which make faith penetrating and pleasant of taste. Thus theology reaches a most fruitful understanding of revealed mysteries, by finding analogies in truths which we know naturally, and also by tracing the intertwining of these mysteries with one another and with the last end of our life. [8].
The present work is an exposition of the Thomistic synthesis, an exposition devoted to the principles often formulated by the saint himself. We do not undertake to prove historically that all the doctrinal points in question are found explicitly in the works of St. Thomas himself, but we will indicate the chief references to his works. And our main task will be to set in relief the certitude and universality of the principles which underlie the structure and coherence of Thomistic doctrine.
