Whether the human intellect can attain to the vision of God in His essence?

❌ Objection 1 : It would seem that the human intellect cannot attain to the vision of God in His essence. For it is written (Jn. 1:18): "No man hath seen God at any time"; and Chrysostom in his commentary says (Hom. xiv in Joan.) that "not even the heavenly essences, namely the Cherubim and Seraphim, have ever been able to see Him as He is." Now, only equality with the angels is promised to men (Mt. 22:30): "They . . . shall be as the angels of God in heaven." Therefore neither will the saints in heaven see God in His essence.

❌ Objection 2 : Further, Dionysius argues thus (Div. Nom. i): "Knowledge is only of existing things." Now whatever exists is finite, since it is confined to a certain genus: and therefore God, since He is infinite, is above all existing things. Therefore there is no knowledge of Him, and He is above all knowledge.

❌ Objection 3 : Further, Dionysius (De Myst. Theol. i) shows that the most perfect way in which our intellect can be united to God is when it is united to Him as to something unknown. Now that which is seen in its essence is not unknown. Therefore it is impossible for our intellect to see God in His essence.

❌ Objection 4 : Further, Dionysius says (Ep. ad Caium Monach.) that "the darkness"---for thus he calls the abundance of light---"which screens God is impervious to all illuminations, and hidden from all knowledge: and if anyone in seeing God understood what he saw, he saw not God Himself, but one of those things that are His." Therefore no created intellect will be able to see God in His essence.

❌ Objection 5 : Further, according to Dionysius (Ep. ad Hieroth.) "God is invisible on account of His surpassing glory." Now His glory surpasses the human intellect in heaven even as on the way. Therefore since He is invisible on the way, so will He be in heaven.

❌ Objection 6 : Further, since the intelligible object is the perfection of the intellect, there must needs be proportion between intelligible and intellect, as between the visible object and the sight. But there is no possible proportion between our intellect and the Divine essence, since an infinite distance separates them. Therefore our intellect will be unable to attain to the vision of the Divine essence.

❌ Objection 7 : Further, God is more distant from our intellect than the created intelligible is from our senses. But the senses can nowise attain to the sight of a spiritual creature. Therefore neither will our intellect be able to attain to the vision of the Divine essence.

❌ Objection 8 : Further, whenever the intellect understands something actually it needs to be informed with the likeness of the object understood, which likeness is the principle of the intellectual operation terminating in that object, even as heat is the principle of heating. Accordingly if our intellect understands God, this must be by means of some likeness informing the intellect itself. Now this cannot be the very essence of God, since form and thing informed must needs have one being, while the Divine essence differs from our intellect in essence and being. Therefore the form whereby our intellect is informed in understanding God must needs be a likeness impressed by God on our intellect. But this likeness, being something created, cannot lead to the knowledge of God except as an effect leads to the knowledge of its cause. Therefore it is impossible for our intellect to see God except through His effect. But to see God through His effect is not to see Him in His essence. Therefore our intellect will be unable to see God in His essence.

❌ Objection 9 : Further, the Divine essence is more distant from our intellect than any angel or intelligence. Now according to Avicenna (Metaph. iii), "the existence of an intelligence in our intellect does not imply that its essence is in our intellect," because in that case our knowledge of the intelligence would be a substance and not an accident, "but that its likeness is impressed on our intellect." Therefore neither is God in our intellect, to be understood by us, except in so far as an impression of Him is in our intellect. But this impression cannot lead to the knowledge of the Divine essence, for since it is infinitely distant from the Divine essence, it degenerates to another image much more than if the image of a white thing were to degenerate to the image of a black thing. Therefore, just as a person in whose sight the image of a white thing degenerates to the image of a black thing, on account of an indisposition in the organ, is not said to see a white thing, so neither will our intellect be able to see God in His essence, since it understands God only by means of this impression.

❌ Objection 10 : : Further, "In things devoid of matter that which understands is the same as that which is understood" (De Anima iii). Now God is supremely devoid of matter. Since then our intellect, which is created, cannot attain to be an uncreated essence, it is impossible for our intellect to see God in His essence.

❌ Objection 11 : : Further, whatever is seen in its essence is known as to what it is. But our intellect cannot know of God what He is, but only what He is not as Dionysius (Coel. Hier. ii) and Damascene (De Fide Orth. i) declare. Therefore our intellect will be unable to see God in His essence.

❌ Objection 12 : : Further, every infinite thing, as such, is unknown. But God is in every way infinite. Therefore He is altogether unknown. Therefore it will be impossible for Him to be seen in His essence by a created intellect.

❌ Objection 13 : : Further, Augustine says (De Videndo Deo: Ep. cxlvii): "God is by nature invisible." Now that which is in God by nature cannot be otherwise. Therefore it is impossible for Him to be seen in His essence.

❌ Objection 14 : : Further, whatever is in one way and is seen in another way is not seen as it is. Now God is in one way and will be seen in another way by the saints in heaven: for He according to His own mode, but will be seen by the saints according to their mode. Therefore He will not be seen by the saints as He is, and thus will not be seen in His essence.

❌ Objection 15 : : Further, that which is seen through a medium is not seen in its essence. Now God will be seen in heaven through a medium which is the light of glory, according to Ps. 35:10, "In Thy light we shall see light." Therefore He will not be seen in His essence.

❌ Objection 16 : : Further, in heaven God will be seen face to face, according to 1 Cor. 13:12. Now when we see a man face to face, we see him through his likeness. Therefore in heaven God will be seen through His likeness, and consequently not in His essence.
