“Since faith rests upon infallible truth, and since the contrary of a truth can never be demonstrated, it is clear that the arguments brought against faith cannot be demonstrations, but are difficulties that can be answered.”

“[I]t is to be borne in mind, in regard to the philosophical sciences, that the inferior sciences neither prove their principles nor dispute with those who deny them, but leave this to a higher science; whereas the highest of them, viz. metaphysics, can dispute with one who denies its principles, if only the opponent will make some concession; but if he concede nothing, it can have no dispute with him, though it can answer his objections. Hence Sacred Scripture, since it has no science above itself, can dispute with one who denies its principles only if the opponent admits some at least of the truths obtained through divine revelation; thus we can argue with heretics from texts in Holy Writ, and against those who deny one article of faith, we can argue from another. If our opponent believes nothing of divine revelation, there is no longer any means of proving the articles of faith by reasoning, but only of answering his objections — if he has any — against faith. Since faith rests upon infallible truth, and since the contrary of a truth can never be demonstrated, it is clear that the arguments brought against faith cannot be demonstrations, but are difficulties that can be answered.”

“The truth can be perceived only through thinking, as is proven by Augustine.”

“God Himself is the rule and mode of virtue. Our faith is measured by divine truth, our hope by the greatness of His power and faithful affection, our charity by His goodness. His truth, power and goodness outreach any measure of reason. We can certainly never believe, trust or love God more than, or even as much as, we should. Extravagance is impossible. Here is no virtuous moderation, no measurable mean; the more extreme our activity, the better we are.”

“The human mind may perceive truth only through thinking, as is clear from Augustine.”

“Give us, O Lord, a steadfast heart, which no unworthy affection may drag downwards; give us an unconquered heart, which no tribulation can wear out; give us an upright heart, which no unworthy purpose may tempt aside. Bestow upon us also, O Lord our God, understanding to know you, diligence to seek you, wisdom to find you, and a faithfulness that may finally embrace you; through Jesus Christ our Lord.”

“Faith has to do with things that are not seen, and hope with things that are not in hand.”
