The faith which redeemed the ancient world and prepared the germs of that degree of civilization that has not been wholly destroyed by Protestantism, was in no respect like the withering, soul-destroying horrors of Calvinism. The doctrines which supplied matter for the intense intellectual life of the middle age, which corrected Aristotle and piled tome after tome of the close, serried reasoning of St. Thomas Aquinas, was in accord with human reason, vindicated the dignity and powers of man, and stimulated him with fresh vigor in every sphere of science, poetry, and art. Scholasticism was nothing else than an effort of human reason to demonstrate the reasonableness of Christianity. The present generation is so grossly ignorant of those eight hundred years of most intense life which formed Christendom that it is not capable of appreciating their influence and still less their character. But whoever will read the _proœmium_ of the _Summa Contra Gentiles_ of the “Angel of the Schools” will see the difference between the constructive doctrine of the middle age and the reactionary delusions of the sixteenth century—the bitter fruit of that splendid revival of paganism. Protestantism, viewed as a system of doctrine, was simply an extravagant caricature of the supernaturalism of the Catholic Church. As a system of morality it was nothing else than the emancipation of the passions from the restraints imposed by Christianity. Having destroyed the necessary conditions of faith by denying authority, it presented the ideas of grace and sanctification in such a distorted manner as to render sacraments unnecessary and unmeaning, to do away with free will, merit, and natural goodness—in a word, to abolish human nature. Wherever the heirs of the so-called Reformers have revolted from the unnatural task of propagating their religious system they have left mankind, not simply bewildered by the darkness whence it has emerged, but without the heavenly guidance which genuine Christianity provides. It has robbed men of the light of heavenly doctrine, and has furthermore stripped them of the aid of the sacramental system, the means of the action of divine grace and of the growth of supernatural life, without which natural virtue and natural intelligence cannot long endure in purity.
