Summa Theologica by Saint Thomas Aquinas (whitelam books .TXT) 📕

I answer that, As stated above (A. 2), the gift of understanding is not only about those things which come under faith first and principally, but also about all things subordinate to faith. Now good actions have a certain relationship to faith: since "faith worketh through charity," according to the Apostle (Gal. 5:6). Hence the gift of understanding extends also to certain actions, not as though these were its principal object, but in so far as the rule of our actions is the eternal law, to which the higher reason, which is perfected by the gift of understanding, adheres by contemplating and consulting it, as Augustine states (De Trin. xii, 7).

Reply Obj. 1: The things with which human actions are concerned are not surpassingly exalted considered in themselves, but, as referred to the rule of the eternal law, and to the end of Divine happiness, they are exalted so that they can be the matter of understanding.

Reply Obj. 2: The excellence of the gift of understanding consists precisely in its considering eternal or necessary matters, not only as they are rules of human actions, because a cognitive virtue is the more excellent, according to the greater extent of its object.

Reply Obj. 3: The rule of human actions is the human reason and the eternal law, as stated above (I-II, Q. 71, A. 6). Now the eternal law surpasses human reason: so that the knowledge of human actions, as ruled by the eternal law, surpasses the natural reason, and requires the supernatural light of a gift of the Holy Ghost. _______________________

Whether the Gift of Understanding Is in All Who Are in a State of
Grace?

Objection 1: It would seem that the gift of understanding is not in all who are in a state of grace. For Gregory says (Moral. ii, 49) that "the gift of understanding is given as a remedy against dulness of mind." Now many who are in a state of grace suffer from dulness of mind. Therefore the gift of understanding is not in all who are in a state of grace.

Obj. 2: Further, of all the things that are connected with knowledge, faith alone seems to be necessary for salvation, since by faith Christ dwells in our hearts, according to Eph. 3:17. Now the gift of understanding is not in everyone that has faith; indeed, those who have faith ought to pray that they may understand, as Augustine says (De Trin. xv, 27). Therefore the gift of understanding is not necessary for salvation: and, consequently, is not in all who are in a state of grace.

Obj. 3: Further, those things which are common to all who are in a state of grace, are never withdrawn from them. Now the grace of understanding and of the other gifts sometimes withdraws itself profitably, for, at times, "when the mind is puffed up with understanding sublime things, it becomes sluggish and dull in base and vile things," as Gregory observes (Moral. ii, 49). Therefore the gift of understanding is not in all who are in a state of grace.

On the contrary, It is written (Ps. 81:5): "They have not known or understood, they walk on in darkness." But no one who is in a state of grace walks in darkness, according to John 8:12: "He that followeth Me, walketh not in darkness." Therefore no one who is in a state of grace is without the gift of understanding.

I answer that, In all who are in a state of grace, there must needs be rectitude of the will, since grace prepares man's will for good, according to Augustine (Contra Julian. Pelag. iv, 3). Now the will cannot be rightly directed to good, unless there be already some knowledge of the truth, since the object of the will is good understood, as stated in De Anima iii, 7. Again, just as the Holy Ghost directs man's will by the gift of charity, so as to move it directly to some supernatural good; so also, by the gift of understanding, He enlightens the human mind, so that it knows some supernatural truth, to which the right will needs to tend.

Therefore, just as the gift of charity is in all of those who have sanctifying grace, so also is the gift of understanding.

Reply Obj. 1: Some who have sanctifying grace may suffer dulness of mind with regard to things that are not necessary for salvation; but with regard to those that are necessary for salvation, they are sufficiently instructed by the Holy Ghost, according to 1 John 2:27: "His unction teacheth you of all things."

Reply Obj. 2: Although not all who have faith understand fully the things that are proposed to be believed, yet they understand that they ought to believe them, and that they ought nowise to deviate from them.

Reply Obj. 3: With regard to things necessary for salvation, the gift of understanding never withdraws from holy persons: but, in order that they may have no incentive to pride, it does withdraw sometimes with regard to other things, so that their mind is unable to penetrate all things clearly. _______________________

FIFTH ARTICLE [II-II, Q. 8, Art. 5]

Whether the Gift of Understanding Is Found Also in Those Who Have Not
Sanctifying Grace?

Objection 1: It would seem that the gift of understanding is found also in those who have not sanctifying grace. For Augustine, in expounding the words of Ps. 118:20: "My soul hath coveted to long for Thy justifications," says: "Understanding flies ahead, and man's will is weak and slow to follow." But in all who have sanctifying grace, the will is prompt on account of charity. Therefore the gift of understanding can be in those who have not sanctifying grace.

Obj. 2: Further, it is written (Dan. 10:1) that "there is need of understanding in a" prophetic "vision," so that, seemingly, there is no prophecy without the gift of understanding. But there can be prophecy without sanctifying grace, as evidenced by Matt. 7:22, where those who say: "We have prophesied in Thy name [*Vulg.: 'Have we not prophesied in Thy name?']," are answered with the words: "I never knew you." Therefore the gift of understanding can be without sanctifying grace.

Obj. 3: Further, the gift of understanding responds to the virtue of faith, according to Isa. 7:9, following another reading [*The Septuagint]: "If you will not believe you shall not understand." Now faith can be without sanctifying grace. Therefore the gift of understanding can be without it.

On the contrary, Our Lord said (John 6:45): "Every one that hath heard of the Father, and hath learned, cometh to Me." Now it is by the intellect, as Gregory observes (Moral. i, 32), that we learn or understand what we hear. Therefore whoever has the gift of understanding, cometh to Christ, which is impossible without sanctifying grace. Therefore the gift of understanding cannot be without sanctifying grace.

I answer that, As stated above (I-II, Q. 68, AA. 1, 2) the gifts of the Holy Ghost perfect the soul, according as it is amenable to the motion of the Holy Ghost. Accordingly then, the intellectual light of grace is called the gift of understanding, in so far as man's understanding is easily moved by the Holy Ghost, the consideration of which movement depends on a true apprehension of the end. Wherefore unless the human intellect be moved by the Holy Ghost so far as to have a right estimate of the end, it has not yet obtained the gift of understanding, however much the Holy Ghost may have enlightened it in regard to other truths that are preambles to the faith.

Now to have a right estimate about the last end one must not be in error about the end, and must adhere to it firmly as to the greatest good: and no one can do this without sanctifying grace; even as in moral matters a man has a right estimate about the end through a habit of virtue. Therefore no one has the gift of understanding without sanctifying grace.

Reply Obj. 1: By understanding Augustine means any kind of intellectual light, that, however, does not fulfil all the conditions of a gift, unless the mind of man be so far perfected as to have a right estimate about the end.

Reply Obj. 2: The understanding that is requisite for prophecy, is a kind of enlightenment of the mind with regard to the things revealed to the prophet: but it is not an enlightenment of the mind with regard to a right estimate about the last end, which belongs to the gift of understanding.

Reply Obj. 3: Faith implies merely assent to what is proposed but understanding implies a certain perception of the truth, which perception, except in one who has sanctifying grace, cannot regard the end, as stated above. Hence the comparison fails between understanding and faith. _______________________

SIXTH ARTICLE [II-II, Q. 8, Art. 6]

Whether the Gift of Understanding Is Distinct from the Other Gifts?

Objection 1: It would seem that the gift of understanding is not distinct from the other gifts. For there is no distinction between things whose opposites are not distinct. Now "wisdom is contrary to folly, understanding is contrary to dulness, counsel is contrary to rashness, knowledge is contrary to ignorance," as Gregory states (Moral. ii, 49). But there would seem to be no difference between folly, dulness, ignorance and rashness. Therefore neither does understanding differ from the other gifts.

Obj. 2: Further, the intellectual virtue of understanding differs from the other intellectual virtues in that it is proper to it to be about self-evident principles. But the gift of understanding is not about any self-evident principles, since the natural habit of first principles suffices in respect of those matters which are naturally self-evident: while faith is sufficient in respect of such things as are supernatural, since the articles of faith are like first principles in supernatural knowledge, as stated above (Q. 1, A. 7). Therefore the gift of understanding does not differ from the other intellectual gifts.

Obj. 3: Further, all intellectual knowledge is either speculative or practical. Now the gift of understanding is related to both, as stated above (A. 3). Therefore it is not distinct from the other intellectual gifts, but comprises them all.

On the contrary, When several things are enumerated together they must be, in some way, distinct from one another, because distinction is the origin of number. Now the gift of understanding is enumerated together with the other gifts, as appears from Isa. 11:2. Therefore the gift of understanding is distinct from the other gifts.

I answer that, The difference between the gift of understanding and three of the others, viz. piety, fortitude, and fear, is evident, since the gift of understanding belongs to the cognitive power, while the three belong to the appetitive power.

But the difference between this gift of understanding and the remaining three, viz. wisdom, knowledge, and counsel, which also belong to the cognitive power, is not so evident. To some [*William of Auxerre, Sum. Aur. III, iii, 8], it seems that the gift of understanding differs from the gifts of knowledge and counsel, in that these two belong to practical knowledge, while the gift of understanding belongs to speculative knowledge; and that it differs from the gift of wisdom, which also belongs to speculative knowledge, in that wisdom is concerned with judgment, while understanding renders the mind apt to grasp the things that are proposed, and to penetrate into their very heart. And in this sense we have assigned the number of the gifts, above (I-II, Q. 68, A. 4).

But if we consider the matter carefully, the gift of understanding is concerned not only with speculative, but also with practical matters, as stated above (A. 3), and likewise, the gift of knowledge regards both matters, as we shall show further on (Q. 9, A. 3), and consequently, we must take their distinction in some other way. For all these four gifts are ordained to supernatural knowledge, which, in us, takes its foundation from faith. Now "faith is through hearing" (Rom. 10:17). Hence some things must be proposed to be believed by man, not as seen, but as heard, to which he assents by faith. But faith, first and principally, is about the First Truth, secondarily, about certain considerations concerning creatures, and furthermore extends to the direction of human actions, in so far as it works through charity, as appears from what has been said above (Q. 4, A. 2, ad 3).

Accordingly on the part of the things proposed to faith for belief, two things are requisite on our part: first that they be penetrated or grasped by the intellect, and this belongs to the gift of understanding. Secondly, it is necessary that man should judge these things aright, that he should esteem
