Whether the image of God is in man according to the Trinity of Persons?
Objection 1: It would seem that the image of God does not exist in man as to the Trinity of Persons. For Augustine says (Fulgentius De Fide ad Petrum i): "One in essence is the Godhead of the Holy Trinity; and one is the image to which man was made." And Hilary (De Trin. v) says: "Man is made to the image of that which is common in the Trinity." Therefore the image of God in man is of the Divine Essence, and not of the Trinity of Persons.
Objection 2: Further, it is said (De Eccl. Dogmat.) that the image of God in man is to be referred to eternity. Damascene also says (De Fide Orth. ii, 12) that the image of God in man belongs to him as "an intelligent being endowed with free-will and self-movement." Gregory of Nyssa (De Homin. Opificio xvi) also asserts that, when Scripture says that "man was made to the image of God, it means that human nature was made a participator of all good: for the Godhead is the fulness of goodness." Now all these things belong more to the unity of the Essence than to the distinction of the Persons. Therefore the image of God in man regards, not the Trinity of Persons, but the unity of the Essence.
Objection 3: Further, an image leads to the knowledge of that of which it is the image. Therefore, if there is in man the image of God as to the Trinity of Persons; since man can know himself by his natural reason, it follows that by his natural knowledge man could know the Trinity of the Divine Persons; which is untrue, as was shown above (Q[32], A[1]).
Objection 4: Further, the name of Image is not applicable to any of the Three Persons, but only to the Son; for Augustine says (De Trin. vi, 2) that "the Son alone is the image of the Father." Therefore, if in man there were an image of God as regards the Person, this would not be an image of the Trinity, but only of the Son.
On the contrary, Hilary says (De Trin. iv): "The plurality of the Divine Persons is proved from the fact that man is said to have been made to the image of God."
I answer that, as we have seen (Q[40], A[2]), the distinction of the Divine Persons is only according to origin, or, rather, relations of origin. Now the mode of origin is not the same in all things, but in each thing is adapted to the nature thereof; animated things being produced in one way, and inanimate in another; animals in one way, and plants in another. Wherefore it is manifest that the distinction of the Divine Persons is suitable to the Divine Nature; and therefore to be to the image of God by imitation of the Divine Nature does not exclude being to the same image by the representation of the Divine Persons: but rather one follows from the other. We must, therefore, say that in man there exists the image of God, both as regards the Divine Nature and as regards the Trinity of Persons; for also in God Himself there is one Nature in Three Persons.
Thus it is clear how to solve the first two objections.
Reply to Objection 3: This argument would avail if the image of God in man represented God in a perfect manner. But, as Augustine says (De Trin. xv, 6), there is a great difference between the trinity within ourselves and the Divine Trinity. Therefore, as he there says: "We see, rather than believe, the trinity which is in ourselves; whereas we believe rather than see that God is Trinity."
Reply to Objection 4: Some have said that in man there is an image of the Son only. Augustine rejects this opinion (De Trin. xii, 5,6). First, because as the Son is like to the Father by a likeness of essence, it would follow of necessity if man were made in likeness to the Son, that he is made to the likeness of the Father. Secondly, because if man were made only to the image of the Son, the Father would not have said, "Let Us make man to Our own image and likeness"; but "to Thy image." When, therefore, it is written, "He made him to the image of God," the sense is not that the Father made man to the image of the Son only, Who is God, as some explained it, but that the Divine Trinity made man to Its image, that is, of the whole Trinity. When it is said that God "made man to His image," this can be understood in two ways: first, so that this preposition "to" points to the term of the making, and then the sense is, "Let Us make man in such a way that Our image may be in him." Secondly, this preposition 'to' may point to the exemplar cause, as when we say, "This book is made (like) to that one." Thus the image of God is the very Essence of God, Which is incorrectly called an image forasmuch as image is put for the exemplar. Or, as some say, the Divine Essence is called an image because thereby one Person imitates another.
Whether the image of God is in man as regards the mind only?
Objection 1: It would seem that the image of God is not only in man's mind. For the Apostle says ( 1 Cor. 11:7 ) that "the man is the image . . . of God." But man is not only mind. Therefore the image of God is to be observed not only in his mind.
Objection 2: Further, it is written ( Gn. 1:27 ): "God created man to His own image; to the image of God He created him; male and female He created them." But the distinction of male and female is in the body. Therefore the image of God is also in the body, and not only in the mind.
Objection 3: Further, an image seems to apply principally to the shape of a thing. But shape belongs to the body. Therefore the image of God is to be seen in man's body also, and not in his mind.
Objection 4: Further, according to Augustine (Gen. ad lit. xii, 7,24) there is a threefold vision in us, "corporeal," "spiritual," or imaginary, and "intellectual." Therefore, if in the intellectual vision that belongs to the mind there exists in us a trinity by reason of which we are made to the image of God, for the like reason there must be another trinity in the others.
On the contrary, The Apostle says ( Eph. 4:23 , 24 ): "Be renewed in the spirit of your mind, and put on the new man." Whence we are given to understand that our renewal which consists in putting on the new man, belongs to the mind. Now, he says ( Col. 3:10 ): "Putting on the new" man; "him who is renewed unto knowledge" of God, "according to the image of Him that created him," where the renewal which consists in putting on the new man is ascribed to the image of God. Therefore to be to the image of God belongs to the mind only.
I answer that, While in all creatures there is some kind of likeness to God, in the rational creature alone we find a likeness of "image" as we have explained above (AA[1],2); whereas in other creatures we find a likeness by way of a "trace." Now the intellect or mind is that whereby the rational creature excels other creatures; wherefore this image of God is not found even in the rational creature except in the mind; while in the other parts, which the rational creature may happen to possess, we find the likeness of a "trace," as in other creatures to which, in reference to such parts, the rational creature can be likened. We may easily understand the reason of this if we consider the way in which a "trace," and the way in which an "image," represents anything. An "image" represents something by likeness in species, as we have said; while a "trace" represents something by way of an effect, which represents the cause in such a way as not to attain to the likeness of species. For imprints which are left by the movements of animals are called "traces": so also ashes are a trace of fire, and desolation of the land a trace of a hostile army.
Therefore we may observe this difference between rational creatures and others, both as to the representation of the likeness of the Divine Nature in creatures, and as to the representation in them of the uncreated Trinity. For as to the likeness of the Divine Nature, rational creatures seem to attain, after a fashion, to the representation of the species, inasmuch as they imitate God, not only in being and life, but also in intelligence, as above explained (A[2]); whereas other creatures do not understand, although we observe in them a certain trace of the Intellect that created them, if we consider their disposition. Likewise as the uncreated Trinity is distinguished by the procession of the Word from the Speaker, and of Love from both of these, as we have seen (Q[28], A[3]); so we may say that in rational creatures wherein we find a procession of the word in the intellect, and a procession of the love in the will, there exists an image of the uncreated Trinity, by a certain representation of the species. In other creatures, however, we do not find the principle of the word, and the word and love; but we do see in them a certain trace of the existence of these in the Cause that produced them. For in the fact that a creature has a modified and finite nature, proves that it proceeds from a principle; while its species points to the (mental) word of the maker, just as the shape of a house points to the idea of the architect; and order points to the maker's love by reason of which he directs the effect to a good end; as also the use of the house points to the will of the architect. So we find in man a likeness to God by way of an "image" in his mind; but in the other parts of his being by way of a "trace."
Reply to Objection 1: Man is called to the image of God; not that he is essentially an image; but that the image of God is impressed on his mind; as a coin is an image of the king, as having the image of the king. Wherefore there is no need to consider the image of God as existing in every part of man.
Reply to Objection 2: As Augustine says (De Trin. xii, 5), some have thought that the image of God was not in man individually, but severally. They held that "the man represents the Person of the Father; those born of man denote the person of the Son; and that the woman is a third person in likeness to the Holy Ghost, since she so proceeded from man as not to be his son or daughter." All of this is manifestly absurd; first, because it would follow that the Holy Ghost is the principle of the Son, as the woman is the principle of the man's offspring; secondly, because one man would be only the image of one Person; thirdly, because in that case Scripture should not have mentioned the image of God in man until after the birth of the offspring. Therefore we must understand that when Scripture had said, "to the image of God He created him," it added, "male and female He created them," not to imply that the image of God came through the distinction of sex, but that the image of God belongs to both sexes, since it is in the mind, wherein there is no sexual distinction of sex, but that the image of God belongs to both sexes, since it is in the mind, wherein there is no sexual distinction. Wherefore the Apostle ( Col. 3:10 ), after saying, "According to the image of Him that created him," added, "Where there is neither male nor female" [*these words are in reality from Gal. 3:28 ] (Vulg. "neither Gentile nor Jew").
Reply to Objection 3: Although the image of God in man is not to be found in his bodily shape, yet because "the body of man alone among terrestrial animals is not inclined prone to the ground, but is adapted to look upward to heaven, for this reason we may rightly say that it is made to God's image and likeness, rather than the bodies of other animals," as Augustine remarks (QQ. 83, qu. 51). But this is not to be understood as though the image of God were in man's body; but in the sense that the very shape of the human body represents the image of God in the soul by way of a trace.
Reply to Objection 4: Both in the corporeal and in the imaginary vision we may find a trinity, as Augustine says (De Trin. xi, 2). For in corporeal vision there is first the species of the exterior body; secondly, the act of vision, which occurs by the impression on the sight of a certain likeness of the said species; thirdly, the intention of the will applying the sight to see, and to rest on what is seen.
Likewise, in the imaginary vision we find first the species kept in the memory; secondly, the vision itself, which is caused by the penetrative power of the soul, that is, the faculty of imagination, informed by the species; and thirdly, we find the intention of the will joining both together. But each of these trinities falls short of the Divine image. For the species of the external body is extrinsic to the essence of the soul; while the species in the memory, though not extrinsic to the soul, is adventitious to it; and thus in both cases the species falls short of representing the connaturality and co-eternity of the Divine Persons. The corporeal vision, too, does not proceed only from the species of the external body, but from this, and at the same time from the sense of the seer; in like manner imaginary vision is not from the species only which is preserved in the memory, but also from the imagination. For these reasons the procession of the Son from the Father alone is not suitably represented. Lastly the intention of the will joining the two together, does not proceed from them either in corporeal or spiritual vision. Wherefore the procession of the Holy Ghost from the Father and the Son is not thus properly represented.
Whether the image of God is to be found in the acts of the soul?
Objection 1: It would seem that the image of God is not found in the acts of the soul. For Augustine says (De Civ. Dei xi, 26), that "man was made to God's image, inasmuch as we exist and know that we exist, and love this existence and knowledge." But to exist does not signify an act. Therefore the image of God is not to be found in the soul's acts.
