Summa Theologica, Part I (Prima Pars) / From the Complete American Edition

by Saint Aquinas Thomas

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. _______________________

SEVENTH ARTICLE [I, Q. 93, Art. 7]

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.

Obj. 2: Further, Augustine (De Trin. ix, 4) assigns God's image in the soul to these three things—mind, knowledge, and love. But mind does not signify an act, but rather the power or the essence of the intellectual soul. Therefore the image of God does not extend to the acts of the soul.

Obj. 3: Further, Augustine (De Trin. x, 11) assigns the image of the Trinity in the soul to "memory, understanding, and will." But these three are "natural powers of the soul," as the Master of the Sentences says (1 Sent. D iii). Therefore the image of God is in the powers, and does not extend to the acts of the soul.

Obj. 4: Further, the image of the Trinity always remains in the soul. But an act does not always remain. Therefore the image of God does not extend to the acts.

On the contrary, Augustine (De Trin. xi, 2 seqq.) assigns the trinity in the lower part of the soul, in relation to the actual vision, whether sensible or imaginative. Therefore, also, the trinity in the mind, by reason of which man is like to God's image, must be referred to actual vision.

I answer that, As above explained (A. 2), a certain representation of the species belongs to the nature of an image. Hence, if the image of the Divine Trinity is to be found in the soul, we must look for it where the soul approaches the nearest to a representation of the species of the Divine Persons. Now the Divine Persons are distinct from each other by reason of the procession of the Word from the Speaker, and the procession of Love connecting Both. But in our soul word "cannot exist without actual thought," as Augustine says (De Trin. xiv, 7). Therefore, first and chiefly, the image of the Trinity is to be found in the acts of the soul, that is, inasmuch as from the knowledge which we possess, by actual thought we form an internal word; and thence break forth into love. But, since the principles of acts are the habits and powers, and everything exists virtually in its principle, therefore, secondarily and consequently, the image of the Trinity may be considered as existing in the powers, and still more in the habits, forasmuch as the acts virtually exist therein.

Reply Obj. 1: Our being bears the image of God so far as it is proper to us, and excels that of the other animals, that is to say, in so far as we are endowed with a mind. Therefore, this trinity is the same as that which Augustine mentions (De Trin. ix, 4), and which consists in mind, knowledge, and love.
