Saint Thomas Aquinas on the Reasonableness of Faith. There is a reason Christian Ages venerated this Great Man for his towering intellect and brilliant understanding, and exposition, of the Truths of Faith. St. Thomas:
"THE Divine Wisdom, that knows all things most fully, has deigned to reveal these her secrets to men, and in proof of them has displayed works beyond the competence of all natural powers, in the wonderful cure of diseases, in the raising of the dead, and what is more wonderful still, in such inspiration of human minds as that simple and ignorant persons, filled with the gift of the Holy Ghost, have gained in an instant the height of wisdom and eloquence.11 By force of the aforesaid proof, without violence of arms, without promise of pleasures, and, most wonderful thing of all, in the midst of the violence of persecutors, a countless multitude, not only of the uneducated but of the wisest men, flocked to the Christian faith, wherein doctrines are preached that transcend all human understanding, pleasures of sense are restrained, and a contempt is taught of all worldly possessions. That mortal minds should assent to such teaching is the greatest of miracles, and a manifest work of divine inspiration leading men to despise the visible and desire only invisible goods. Nor did this happen suddenly nor by chance, but by a divine disposition, as is manifest from the fact that God foretold by many oracles of His prophets that He intended to do this. The books of those prophets are still venerated amongst us, as bearing testimony to our faith. This argument is touched upon in the text: Which (salvation) having begun to be uttered by the Lord, was confirmed by them that heard him even unto us, God joining in the testimony by signs and portents and various distributions of the Holy Spirit (Heb. ii, 3, 4). This so wonderful conversion of the world to the Christian faith is so certain a sign of past miracles, that they need no further reiteration, since they appear evidently in their effects. It would be more wonderful than all other miracles, if without miraculous signs the world had been induced by simple and low-born men to believe truths so arduous, to do works so difficult, to hope for reward so high. And yet even in our times God ceases not through His saints to work miracles for the confirmation of the faith.12"
