Thomas Aquinas - Summa Theologica, Part III (Tertia Pars)

Reply Obj. 3: That which is infinite in every way can be but one. Hence the Philosopher says (De Coel. i, 2, 3) that, since bodies have dimensions in every part, there cannot be several infinite bodies. Yet if anything were infinite in one way only, nothing would hinder the existence of several such infinite things; as if we were to suppose several lines of infinite length drawn on a surface of finite breadth. Hence, because infinitude is not a substance, but is accidental to things that are said to be infinite, as the Philosopher says (Phys. iii, 37, 38); as the infinite is multiplied by different subjects, so, too, a property of the infinite must be multiplied, in such a way that it belongs to each of them according to that particular subject. Now it is a property of the infinite that nothing is greater than it. Hence, if we take one infinite line, there is nothing greater in it than the infinite; so, too, if we take any one of other infinite lines, it is plain that each has infinite parts. Therefore of necessity in this particular line there is nothing greater than all these infinite parts; yet in another or a third line there will be more infinite parts besides these. We observe this in numbers also, for the species of even numbers are infinite, and likewise the species of odd numbers are infinite; yet there are more even and odd numbers than even. And thus it must be said that nothing is greater than the simply and in every way infinite; but than the infinite which is limited in some respect, nothing is greater in that order; yet we may suppose something greater outside that order. In this way, therefore, there are infinite things in the potentiality of the creature, and yet there are more in the power of God than in the potentiality of the creature. So, too, the soul of Christ knows infinite things by the knowledge of simple intelligence; yet God knows more by this manner of knowledge or understanding. _______________________

FOURTH ARTICLE [III, Q. 10, Art. 4]

Whether the Soul of Christ Sees the Word or the Divine Essence More

Clearly Than Does Any Other Creature?

Objection 1: It would seem that the soul of Christ does not see the Word more perfectly than does any other creature. For the perfection of knowledge depends upon the medium of knowing; as the knowledge we have by means of a demonstrative syllogism is more perfect than that which we have by means of a probable syllogism. But all the blessed see the Word immediately in the Divine Essence Itself, as was said in the First Part (Q. 12, A. 2). Therefore the soul of Christ does not see the Word more perfectly than any other creature.

Obj. 2: Further, the perfection of vision does not exceed the power of seeing. But the rational power of a soul such as is the soul of Christ is below the intellective power of an angel, as is plain from Dionysius (Coel. Hier. iv). Therefore the soul of Christ did not see the Word more perfectly than the angels.

Obj. 3: Further, God sees His Word infinitely more perfectly than does the soul of Christ. Hence there are infinite possible mediate degrees between the manner in which God sees His Word, and the manner in which the soul of Christ sees the Word. Therefore we cannot assert that the soul of Christ sees the Word or the Divine Essence more perfectly than does every other creature.

On the contrary, The Apostle says (Eph. 1:20, 21) that God set Christ "on His right hand in the heavenly places, above all principality and power and virtue and dominion and every name that is named not only in this world, but also in that which is to come." But in that heavenly glory the higher anyone is the more perfectly does he know God. Therefore the soul of Christ sees God more perfectly than does any other creature.

I answer that, The vision of the Divine Essence is granted to all the blessed by a partaking of the Divine light which is shed upon them from the fountain of the Word of God, according to Ecclus. 1:5: "The Word of God on high is the fountain of Wisdom." Now the soul of Christ, since it is united to the Word in person, is more closely joined to the Word of God than any other creature. Hence it more fully receives the light in which God is seen by the Word Himself than any other creature. And therefore more perfectly than the rest of creatures it sees the First Truth itself, which is the Essence of God; hence it is written (John 1:14): "And we saw His glory, the glory as it were of the Only-begotten of the Father," "full" not only of "grace" but also of "truth."

Reply Obj. 1: Perfection of knowledge, on the part of the thing known, depends on the medium; but as regards the knower, it depends on the power or habit. And hence it is that even amongst men one sees a conclusion in a medium more perfectly than another does. And in this way the soul of Christ, which is filled with a more abundant light, knows the Divine Essence more perfectly than do the other blessed, although all see the Divine Essence in itself.

Reply Obj. 2: The vision of the Divine Essence exceeds the natural power of any creature, as was said in the First Part (Q. 12, A. 4). And hence the degrees thereof depend rather on the order of grace in which Christ is supreme, than on the order of nature, in which the angelic nature is placed before the human.

Reply Obj. 3: As stated above (Q. 7, A. 12), there cannot be a greater grace than the grace of Christ with respect to the union with the Word; and the same is to be said of the perfection of the Divine vision; although, absolutely speaking, there could be a higher and more sublime degree by the infinity of the Divine power.

We must now consider the knowledge imprinted or infused in the soul of Christ, and under this head there are six points of inquiry:

(1) Whether Christ knows all things by this knowledge?

(2) Whether He could use this knowledge by turning to phantasms?

(3) Whether this knowledge was collative?

(4) Of the comparison of this knowledge with the angelic knowledge;

(5) Whether it was a habitual knowledge?

(6) Whether it was distinguished by various habits? _______________________

FIRST ARTICLE [III, Q. 11, Art. 1]

Whether by This Imprinted or Infused Knowledge Christ Knew All Things?

Objection 1: It would seem that by this knowledge Christ did not know all things. For this knowledge is imprinted upon Christ for the perfection of the passive intellect. Now the passive intellect of the human soul does not seem to be in potentiality to all things simply, but only to those things with regard to which it can be reduced to act by the active intellect, which is its proper motor; and these are knowable by natural reason. Therefore by this knowledge Christ did not know what exceeded the natural reason.

Obj. 2: Further, phantasms are to the human intellect as colors to sight, as is said De Anima iii, 18, 31, 39. But it does not pertain to the perfection of the power of seeing to know what is without color. Therefore it does not pertain to the perfection of human intellect to know things of which there are no phantasms, such as separate substances. Hence, since this knowledge was in Christ for the perfection of His intellective soul, it seems that by this knowledge He did not know separate substances.

Obj. 3: Further, it does not belong to the perfection of the intellect to know singulars. Hence it would seem that by this knowledge the soul of Christ did not know singulars.

On the contrary, It is written (Isa. 11:2) that "the Spirit of wisdom and understanding, of knowledge and counsel shall fill Him [*Vulg.: 'The Spirit of the Lord shall rest upon Him, the Spirit of wisdom and understanding, the Spirit of counsel . . . the Spirit of knowledge . . . '; cf. Ecclus. 15:5," under which are included all that may be known; for the knowledge of all Divine things belongs to wisdom, the knowledge of all immaterial things to understanding, the knowledge of all conclusions to knowledge ( scientia ), the knowledge of all practical things to counsel. Hence it would seem that by this knowledge Christ had the knowledge of all things.
