Whether Christ had the knowledge which the blessed or comprehensors have?
Objection 1: It would seem that in Christ there was not the knowledge of the blessed or comprehensors. For the knowledge of the blessed is a participation of Divine light, according to Ps. 35:10: "In Thy light we shall see light." Now Christ had not a participated light, but He had the Godhead Itself substantially abiding in Him, according to Col. 2:9: "For in Him dwelleth all the fulness of the Godhead corporeally." Therefore in Christ there was not the knowledge of the blessed.
Objection 2: Further, the knowledge of the blessed makes them blessed, according to Jn. 17:3: "This is eternal life: that they may know Thee, the only true God, and Jesus Christ Whom Thou hast sent." But this Man was blessed through being united to God in person, according to Ps. 64:5: "Blessed is He Whom Thou hast chosen and taken to Thee." Therefore it is not necessary to suppose the knowledge of the blessed in Him.
Objection 3: Further, to man belongs a double knowledge---one by nature, one above nature. Now the knowledge of the blessed, which consists in the vision of God, is not natural to man, but above his nature. But in Christ there was another and much higher supernatural knowledge, i.e. the Divine knowledge. Therefore there was no need of the knowledge of the blessed in Christ.
On the contrary, The knowledge of the blessed consists in the knowledge of God. But He knew God fully, even as He was man, according to Jn. 8:55: "I do know Him, and do keep His word." Therefore in Christ there was the knowledge of the blessed.
I answer that, What is in potentiality is reduced to act by what is in act; for that whereby things are heated must itself be hot. Now man is in potentiality to the knowledge of the blessed, which consists in the vision of God; and is ordained to it as to an end; since the rational creature is capable of that blessed knowledge, inasmuch as he is made in the image of God. Now men are brought to this end of beatitude by the humanity of Christ, according to Heb. 2:10: "For it became Him, for Whom are all things, and by Whom are all things, Who had brought many children unto glory, to perfect the author of their salvation by His passion." And hence it was necessary that the beatific knowledge, which consists in the vision of God, should belong to Christ pre-eminently, since the cause ought always to be more efficacious than the effect.
Reply to Objection 1: The Godhead is united to the manhood of Christ in Person, not in essence or nature; yet with the unity of Person remains the distinction of natures. And therefore the soul of Christ, which is a part of human nature, through a light participated from the Divine Nature, is perfected with the beatific knowledge whereby it sees God in essence.
Reply to Objection 2: By the union this Man is blessed with the uncreated beatitude, even as by the union He is God; yet besides the uncreated beatitude it was necessary that there should be in the human nature of Christ a created beatitude, whereby His soul was established in the last end of human nature.
Reply to Objection 3: The beatific vision and knowledge are to some extent above the nature of the rational soul, inasmuch as it cannot reach it of its own strength; but in another way it is in accordance with its nature, inasmuch as it is capable of it by nature, having been made to the likeness of God, as stated above. But the uncreated knowledge is in every way above the nature of the human soul.
III · Q. 9, Art. 3: Whether Christ had an imprinted or infused knowledge?
Whether Christ had an imprinted or infused knowledge?
Objection 1: It would seem that there was not in Christ another infused knowledge besides the beatific knowledge. For all other knowledge compared to the beatific knowledge is like imperfect to perfect. But imperfect knowledge is removed by the presence of perfect knowledge, as the clear "face-to-face" vision removes the enigmatical vision of faith, as is plain from 1 Cor. 13:10,12. Since, therefore, in Christ there was the beatific knowledge, as stated above (A 2), it would seem that there could not be any other imprinted knowledge.
Objection 2: Further, an imperfect mode of cognition disposes towards a more perfect, as opinion, the result of dialectical syllogisms, disposes towards science, which results from demonstrative syllogisms. Now, when perfection is reached, there is no further need of the disposition, even as on reaching the end motion is no longer necessary. Hence, since every created cognition is compared to beatific cognition, as imperfect to perfect and as disposition to its term, it seems that since Christ had beatific knowledge, it was not necessary for Him to have any other knowledge.
Objection 3: Further, as corporeal matter is in potentiality to sensible forms, so the possible intellect is in potentiality to intelligible forms. Now corporeal matter cannot receive two forms at once! one more perfect and the other less perfect. Therefore neither can the soul receive a double knowledge at once, one more perfect and the other less perfect; and hence the same conclusion as above.
On the contrary, It is written (Col. 2:3) that in Christ "are hid all the treasures of wisdom and knowledge."
I answer that, As stated above (A 1), it was fitting that the human nature assumed by the Word of God should not be imperfect. Now everything in potentiality is imperfect unless it be reduced to act. But the passive intellect of man is in potentiality to all intelligible things. and it is reduced to act by intelligible species, which are its completive forms, as is plain from what is said De Anima iii, 32,38. And hence we must admit in the soul of Christ an infused knowledge, inasmuch as the Word of God imprinted upon the soul of Christ, which is personally united to Him, intelligible species of all things to which the possible intellect is in potentiality; even as in the beginning of the creation of things, the Word of God imprinted intelligible species upon the angelic mind, as is clear from Augustine (Gen. ad lit. ii, 8). And therefore, even as in the angels, according to Augustine (Gen. ad lit. iv, 22,24,30), there is a double knowledge---one the morning knowledge, whereby they know things in the Word; the other the evening knowledge, whereby they know things in their proper natures by infused species; so likewise, besides the Divine and uncreated knowledge in Christ, there is in His soul a beatific knowledge, whereby He knows the Word, and things in the Word; and an infused or imprinted knowledge, whereby He knows things in their proper nature by intelligible species proportioned to the human mind.
Reply to Objection 1: The imperfect vision of faith is essentially opposed to manifest vision, seeing that it is of the essence of faith to have reference to the unseen, as was said above (SS, Q 1, A 4). But cognition by infused species includes no opposition to beatific cognition. Therefore there is no parity.
Reply to Objection 2: Disposition is referred to perfection in two ways: first, as a way leading to perfection; secondly, as an effect proceeding from perfection; thus matter is disposed by heat to receive the form of fire, and, when this comes, the heat does not cease, but remains as an effect of this form. So, too, opinion caused by a dialectical syllogism is a way to knowledge, which is acquired by demonstration, yet, when this has been acquired, there may still remain the knowledge gained by the dialectical syllogism, following, so to say, the demonstrative knowledge, which is based on the cause, since he who knows the cause is thereby enabled the better to understand the probable signs from which dialectical syllogisms proceed. So likewise in Christ, together with the beatific knowledge, there still remains infused knowledge, not as a way to beatitude, but as strengthened by beatitude.
Reply to Objection 3: The beatific knowledge is not by a species, that is a similitude of the Divine Essence, or of whatever is known in the Divine Essence, as is plain from what has been said in the FP, Q 12, A 2; but it is a knowledge of the Divine Essence immediately, inasmuch as the Divine Essence itself is united to the beatified mind as an intelligible to an intelligent being; and the Divine Essence is a form exceeding the capacity of any creature whatsoever. Hence, together with this super-exceeding form, there is nothing to hinder from being in the rational mind, intelligible species, proportioned to its nature.
