Any one who shares such ideas about the supernaturalness of the Catholic Church has, of course, forfeited his claim to understand Catholic life and faith. The Catholic believes in his Church, not on any account of Asiatic patriarchs and superstitious dignitaries, but because she is led by the Holy Ghost, and the Pope must believe the same as the humblest of the faithful: neither the Pope himself relies upon his own judgment, nor does the Catholic who trusts in the word of the Pope. We add a few remarks which may further illustrate the action of faith. The knowledge of the fact of revelation, hence of the credibility of the truths revealed, is certain, as shown above. Nevertheless, _it does not compel_ reason to assent. Under ordinary circumstances it would be impossible to think of one’s own existence, of the elementary laws of mathematics, without being constrained by the evidence to give direct internal assent. But insight into the truth of a thing is not always of this high degree of clearness. In such cases it is an empirical law of the mind that reason discerns of itself the _logical_ necessity, that is, if it desires to proceed according to the merits of the case, without, however, acting under _physical_ constraint. There remains then the determination, the command of the will. This is generally true of many judgments about natural things, but especially true of belief. The knowledge of the fact of revelation is true and certain, though it might be still clearer. The truths offered by divine revelation are too deep for us to comprehend them fully; they imply questions and difficulties for us to ponder. We feel the physical possibility of pondering these difficulties, although we see at the same time that the difficulty is exploded by the certainty of the fact of revelation; but we remain _free_ in giving our assent. Herein lies the possibility of _meritorious_ faith, the possibility of the creature rendering to God the free tribute of his free submission. At the same time it opens the possibility of turning voluntarily to doubts, and of submitting to them more and more, till the mind becomes clouded and ensnared by error. Thus, since faith depends on free will, the will is strictly commanded to impel the intellect to assent and cling to faith and to put aside doubts. God has revealed the truths of faith that they may be firmly believed.
