Of Christ's Knowledge in General

Of Christ's Knowledge in General — St. Thomas Aquinas asks: Whether Christ had any knowledge besides the Divine?; Whether Christ had the knowledge which the blessed or comprehensors have?; Whether Christ had an imprinted or infused knowledge?; Whether Christ had any acquired knowledge?.

We must now consider Christ's knowledge; concerning which the consideration will be twofold. First, of Christ's knowledge in general; secondly, of each particular kind of knowledge He had.

Under the first head there are four points of inquiry:

Article 1: Whether Christ had any knowledge besides the Divine?

Ambrose says (De Incarnat. vii): "God assumed the perfection of human nature in the flesh; He took upon Himself the sense of man, but not the swollen sense of the flesh." But created knowledge pertains to the sense of man. Therefore in Christ there was created knowledge.

As said above (), the Son of God assumed an entire human nature, i.e. not only a body, but also a soul, and not only a sensitive, but also a rational soul. And therefore it behooved Him to have created knowledge, for three reasons. First, on account of the soul's perfection. For the soul, considered in itself, is in potentiality to knowing intelligible things. since it is like "a tablet on which nothing is written," and yet it may be written upon through the possible intellect, whereby it may become all things, as is said De Anima iii, 18. Now what is in potentiality is imperfect unless reduced to act. But it was fitting that the Son of God should assume, not an imperfect, but a perfect human nature, since the whole human race was to be brought back to perfection by its means. Hence it behooved the soul of Christ to be perfected by a knowledge, which would be its proper perfection. And therefore it was necessary that there should be another knowledge in Christ besides the Divine knowledge, otherwise the soul of Christ would have been more imperfect than the souls of the rest of men. Secondly, because, since everything is on account of its operation, as stated De Coel. ii, 17, Christ would have had an intellective soul to no purpose if He had not understood by it; and this pertains to created knowledge. Thirdly, because some created knowledge pertains to the nature of the human soul, viz. that whereby we naturally know first principles; since we are here taking knowledge for any cognition of the human intellect. Now nothing natural was wanting to Christ, since He took the whole human nature, as stated above (). And hence the Sixth Council [*Third Council of Constantinople, Act. 4] condemned the opinion of those who denied that in Christ there are two knowledges or wisdoms.

Article 2: Whether Christ had the knowledge which the blessed or comprehensors have?

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.

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.

Article 3: Whether Christ had an imprinted or infused knowledge?

It is written (Col. 2:3) that in Christ "are hid all the treasures of wisdom and knowledge."

As stated above (), 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.

Article 4: Whether Christ had any acquired knowledge?

It is written (Heb. 5:8): "Whereas . . . He was the Son of God, He learned obedience by the things which He suffered," i.e. "experienced," says a gloss. Therefore there was in the soul of Christ an empiric knowledge, which is acquired knowledge.

As is plain from , nothing that God planted in our nature was wanting to the human nature assumed by the Word of God. Now it is manifest that God planted in human nature not only a passive, but an active intellect. Hence it is necessary to say that in the soul of Christ there was not merely a passive, but also an active intellect. But if in other things God and nature make nothing in vain, as the Philosopher says (De Coel. i, 31; ii, 59), still less in the soul of Christ is there anything in vain. Now what has not its proper operation is useless, as is said in De Coel. ii, 17. Now the proper operation of the active intellect is to make intelligible species in act, by abstracting them from phantasms; hence, it is said (De Anima iii, 18) that the active intellect is that "whereby everything is made actual." And thus it is necessary to say that in Christ there were intelligible species received in the passive intellect by the action of the active intellect---which means that there was acquired knowledge in Him, which some call empiric. And hence, although I wrote differently (Sent. iii, D, xiv, ; D, xviii, ), it must be said that in Christ there was acquired knowledge, which is properly knowledge in a human fashion, both as regards the subject receiving and as regards the active cause. For such knowledge springs from Christ's active intellect, which is natural to the human soul. But infused knowledge is attributed to the soul, on account of a light infused from on high, and this manner of knowing is proportioned to the angelic nature. But the beatific knowledge, whereby the very Essence of God is seen, is proper and natural to God alone, as was said in the .
