“ Every gift of grace raises man to something above human nature, and this may happen in two ways. First, as to the substance of the act---for instance, the working of miracles, and the knowledge of the uncertain and hidden things of Divine wisdom---and for such acts man is not granted a habitual gift of grace. Secondly, a thing is above human nature as to the mode but not the substance of the act---for instance to love God and to know Him in the mirror of His creatures---and for this a habitual gift of grace is bestowed.
Art. 3 - Whether prophecy is only about future contingencies? ”

“ Therefore all possible matters of prophecy are revealed to the prophet.
Objection 3: Further, the Divine light which causes prophecy is more powerful than the right of natural reason which is the cause of human science. Now a man who has acquired a science knows whatever pertains to that science; thus a grammarian knows all matters of grammar. Therefore it would seem that a prophet knows all matters of prophecy. ”

“ Hence he who knows a principle perfectly, as regards all to which its virtue extends, knows at the same time all that can be known through that principle; whereas if the common principle is unknown, or known only in a general way, it does not follow that one knows all those things at the same time, but each of them has to be manifested by itself, so that consequently some of them may be known, and some not. ”

“ On the other hand, his position with regard to the things he knows by instinct is sometimes such that he is unable to distinguish fully whether his thoughts are conceived of Divine instinct or of his own spirit. And those things which we know by Divine instinct are not all manifested with prophetic certitude, for this instinct is something imperfect in the genus of prophecy. ”

“ Further, in a conditional proposition, whenever the antecedent is absolutely necessary, the consequent is absolutely necessary, because the consequent of a conditional proposition stands in the same relation to the antecedent, as the conclusion to the premises in a syllogism, and a syllogism whose premises are necessary always leads to a necessary conclusion, as we find proved in I Poster. 6. But if the matter of a prophecy cannot be false, the following conditional proposition must needs be true: "If a thing has been prophesied, it will be." ”

“ Just as in corporeal things, when a passion ceases, there remains a certain aptitude to a repetition of the passion---thus wood once ignited is more easily ignited again, so too in the prophet's intellect, after the actual enlightenment has ceased, there remains an aptitude to be enlightened anew---thus when the mind has once been aroused to devotion, it is more easily recalled to its former devotion. ”

“ Consequently it does not follow that nothing is lacking to prophetic revelation, but that it lacks none of those things to which prophecy is directed.
Reply to Objection 3: He who has a science knows the principles of that science, whence whatever is pertinent to that science depends; wherefore to have the habit of a science perfectly, is to know whatever is pertinent to that science. But God Who is the principle of prophetic knowledge is not known in Himself through prophecy ”

“ I answer that, As the Apostle says (Eph. 5:13) , "all that is made manifest is light," because, to wit, just as the manifestation of the material sight takes place through material light, so too the manifestation of intellectual sight takes place through intellectual light. ”

“ Another difference arises from the diversities of life, namely the active and the contemplative life, which correspond to diverse purposes of operation, wherefore it is stated (1 Cor. 12:4, 7) that "there are diversities of operations." For the purpose of operation in Martha, who "was busy about much serving," which pertains to the active life, differed from the purpose of operation in Mary, "who sitting . ”
