FIRST ARTICLE [I, Q. 12, Art. 1]

Whether Any Created Intellect Can See the Essence of God?

Objection 1: It seems that no created intellect can see the essence of God. For Chrysostom (Hom. xiv. in Joan.) commenting on John 1:18, "No man hath seen God at any time," says: "Not prophets only, but neither angels nor archangels have seen God. For how can a creature see what is increatable?" Dionysius also says (Div. Nom. i), speaking of God: "Neither is there sense, nor image, nor opinion, nor reason, nor knowledge of Him."

Obj. 2: Further, everything infinite, as such, is unknown. But

God is infinite, as was shown above (Q. 7, A. 1). Therefore in

Himself He is unknown.

Obj. 3: Further, the created intellect knows only existing things. For what falls first under the apprehension of the intellect is being. Now God is not something existing; but He is rather super-existence, as Dionysius says (Div. Nom. iv). Therefore God is not intelligible; but above all intellect.

Obj. 4: Further, there must be some proportion between the knower and the known, since the known is the perfection of the knower. But no proportion exists between the created intellect and God; for there is an infinite distance between them. Therefore the created intellect cannot see the essence of God.

On the contrary, It is written: "We shall see Him as He is" (1 John 2:2).

I answer that, Since everything is knowable according as it is actual, God, Who is pure act without any admixture of potentiality, is in Himself supremely knowable. But what is supremely knowable in itself, may not be knowable to a particular intellect, on account of the excess of the intelligible object above the intellect; as, for example, the sun, which is supremely visible, cannot be seen by the bat by reason of its excess of light.

Therefore some who considered this, held that no created intellect can see the essence of God. This opinion, however, is not tenable. For as the ultimate beatitude of man consists in the use of his highest function, which is the operation of his intellect; if we suppose that the created intellect could never see God, it would either never attain to beatitude, or its beatitude would consist in something else beside God; which is opposed to faith. For the ultimate perfection of the rational creature is to be found in that which is the principle of its being; since a thing is perfect so far as it attains to its principle. Further the same opinion is also against reason. For there resides in every man a natural desire to know the cause of any effect which he sees; and thence arises wonder in men. But if the intellect of the rational creature could not reach so far as to the first cause of things, the natural desire would remain void.

Hence it must be absolutely granted that the blessed see the essence of God.

Reply Obj. 1: Both of these authorities speak of the vision of comprehension. Hence Dionysius premises immediately before the words cited, "He is universally to all incomprehensible," etc. Chrysostom likewise after the words quoted says: "He says this of the most certain vision of the Father, which is such a perfect consideration and comprehension as the Father has of the Son."

Reply Obj. 2: The infinity of matter not made perfect by form, is unknown in itself, because all knowledge comes by the form; whereas the infinity of the form not limited by matter, is in itself supremely known. God is Infinite in this way, and not in the first way: as appears from what was said above (Q. 7, A. 1).

Reply Obj. 3: God is not said to be not existing as if He did not exist at all, but because He exists above all that exists; inasmuch as He is His own existence. Hence it does not follow that He cannot be known at all, but that He exceeds every kind of knowledge; which means that He is not comprehended.

Reply Obj. 4: Proportion is twofold. In one sense it means a certain relation of one quantity to another, according as double, treble and equal are species of proportion. In another sense every relation of one thing to another is called proportion. And in this sense there can be a proportion of the creature to God, inasmuch as it is related to Him as the effect of its cause, and as potentiality to its act; and in this way the created intellect can be proportioned to know God. _______________________

SECOND ARTICLE [I, Q. 12, Art. 2]

Whether the Essence of God Is Seen by the Created Intellect Through an

Image?

Objection 1: It seems that the essence of God is seen through an image by the created intellect. For it is written: "We know that when He shall appear, we shall be like to Him, and [Vulg.: 'because'] we shall see Him as He is" (1 John 3:2).

Obj. 2: Further, Augustine says (De Trin. v): "When we know God, some likeness of God is made in us."

Obj. 3: Further, the intellect in act is the actual intelligible; as sense in act is the actual sensible. But this comes about inasmuch as sense is informed with the likeness of the sensible object, and the intellect with the likeness of the thing understood. Therefore, if God is seen by the created intellect in act, it must be that He is seen by some similitude.

On the contrary, Augustine says (De Trin. xv) that when the Apostle says, "We see through a glass and in an enigma [*Douay: 'in a dark manner']," "by the terms 'glass' and 'enigma' certain similitudes are signified by him, which are accommodated to the vision of God." But to see the essence of God is not an enigmatic nor a speculative vision, but is, on the contrary, of an opposite kind. Therefore the divine essence is not seen through a similitude.

I answer that, Two things are required both for sensible and for intellectual vision—viz. power of sight, and union of the thing seen with the sight. For vision is made actual only when the thing seen is in a certain way in the seer. Now in corporeal things it is clear that the thing seen cannot be by its essence in the seer, but only by its likeness; as the similitude of a stone is in the eye, whereby the vision is made actual; whereas the substance of the stone is not there. But if the principle of the visual power and the thing seen were one and the same thing, it would necessarily follow that the seer would receive both the visual power and the form whereby it sees, from that one same thing.

Now it is manifest both that God is the author of the intellectual power, and that He can be seen by the intellect. And since the intellective power of the creature is not the essence of God, it follows that it is some kind of participated likeness of Him who is the first intellect. Hence also the intellectual power of the creature is called an intelligible light, as it were, derived from the first light, whether this be understood of the natural power, or of some perfection superadded of grace or of glory. Therefore, in order to see God, there must be some similitude of God on the part of the visual faculty, whereby the intellect is made capable of seeing God. But on the part of the object seen, which must necessarily be united to the seer, the essence of God cannot be seen by any created similitude. First, because as Dionysius says (Div. Nom. i), "by the similitudes of the inferior order of things, the superior can in no way be known;" as by the likeness of a body the essence of an incorporeal thing cannot be known. Much less therefore can the essence of God be seen by any created likeness whatever. Secondly, because the essence of God is His own very existence, as was shown above (Q. 3, A. 4), which cannot be said of any created form; and so no created form can be the similitude representing the essence of God to the seer. Thirdly, because the divine essence is uncircumscribed, and contains in itself super-eminently whatever can be signified or understood by the created intellect. Now this cannot in any way be represented by any created likeness; for every created form is determined according to some aspect of wisdom, or of power, or of being itself, or of some like thing. Hence to say that God is seen by some similitude, is to say that the divine essence is not seen at all; which is false.
