Of the Acquired or Empiric Knowledge of Christ's Soul

Of the Acquired or Empiric Knowledge of Christ's Soul — St. Thomas Aquinas asks: Whether Christ knew all things by this acquired or empiric knowledge?; Whether Christ advanced in acquired or empiric knowledge?; Whether Christ learned anything from man?; Whether Christ received knowledge from the angels?.

We must now consider the acquired or empiric knowledge of Christ's soul; and under this head there are four points of inquiry:

Article 1: Whether Christ knew all things by this acquired or empiric knowledge?

Nothing imperfect was in Christ's soul. Now this knowledge of His would have been imperfect if He had not known all things by it, since the imperfect is that to which addition may be made. Hence Christ knew all things by this knowledge.

Acquired knowledge is held to be in Christ's soul, as we have said[3997] , by reason of the active intellect, lest its action, which is to make things actually intelligible, should be wanting; even as imprinted or infused knowledge is held to be in Christ's soul for the perfection of the passive intellect. Now as the passive intellect is that by which "all things are in potentiality," so the active intellect is that by which "all are in act," as is said De Anima iii, 18. And hence, as the soul of Christ knew by infused knowledge all things to which the passive intellect is in any way in potentiality, so by acquired knowledge it knew whatever can be known by the action of the active intellect.

Article 2: Whether Christ advanced in acquired or empiric knowledge?

It is written (Lk. 2:52): "Jesus advanced in wisdom and age and grace with God and men"; and Ambrose says (De Incar. Dom. vii) that "He advanced in human wisdom." Now human wisdom is that which is acquired in a human manner, i.e. by the light of the active intellect. Therefore Christ advanced in this knowledge.

There is a twofold advancement in knowledge: one in essence, inasmuch as the habit of knowledge is increased; the other in effect---e.g. if someone were with one and the same habit of knowledge to prove to someone else some minor truths at first, and afterwards greater and more subtle conclusions. Now in this second way it is plain that Christ advanced in knowledge and grace, even as in age, since as His age increased He wrought greater deeds, and showed greater knowledge and grace.

But as regards the habit of knowledge, it is plain that His habit of infused knowledge did not increase, since from the beginning He had perfect infused knowledge of all things; and still less could His beatific knowledge increase; while in the , we have already said that His Divine knowledge could not increase. Therefore, if in the soul of Christ there was no habit of acquired knowledge, beyond the habit of infused knowledge, as appears to some [*Blessed Albert the Great, Alexander of Hales, St. Bonaventure], and sometime appeared to me (Sent. iii, D, xiv), no knowledge in Christ increased in essence, but merely by experience, i.e. by comparing the infused intelligible species with phantasms. And in this way they maintain that Christ's knowledge grew in experience, e.g. by comparing the infused intelligible species with what He received through the senses for the first time. But because it seems unfitting that any natural intelligible action should be wanting to Christ, and because to extract intelligible species from phantasms is a natural action of man's active intellect, it seems becoming to place even this action in Christ. And it follows from this that in the soul of Christ there was a habit of knowledge which could increase by this abstraction of species; inasmuch as the active intellect, after abstracting the first intelligible species from phantasms, could abstract others, and others again.

Article 3: Whether Christ learned anything from man?

It is written (Ps. 45:4): "Behold, I have given Him for a witness to the people, for a leader and a master to the Gentiles." Now a master is not taught, but teaches. Therefore Christ did not receive any knowledge by the teaching of any man.

In every genus that which is the first mover is not moved according to the same species of movement; just as the first alterative is not itself altered. Now Christ is established by God the Head of the Church---yea, of all men, as was said above (), so that not only all might receive grace through Him, but that all might receive the doctrine of Truth from Him. Hence He Himself says (Jn. 18:37): "For this was I born, and for this came I into the world; that I should give testimony to the truth." And thus it did not befit His dignity that He should be taught by any man.

Article 4: Whether Christ received knowledge from the angels?

Dionysius says (Coel. Hier. vii) that "the highest angels question Jesus, and learn the knowledge of His Divine work, and of the flesh assumed for us; and Jesus teaches them directly." Now to teach and to be taught do not belong to the same. Therefore Christ did not receive knowledge from the angels.

Since the human soul is midway between spiritual substances and corporeal things, it is perfected naturally in two ways. First by knowledge received from sensible things; secondly, by knowledge imprinted or infused by the illumination of spiritual substances. Now in both these ways the soul of Christ was perfected; first by empirical knowledge of sensible things, for which there is no need of angelic light, since the light of the active intellect suffices; secondly, by the higher impression of infused knowledge, which He received directly from God. For as His soul was united to the Word above the common mode, in unity of person, so above the common manner of men was it filled with knowledge and grace by the Word of God Himself; and not by the medium of angels, who in their beginning received the knowledge of things by the influence of the Word, as Augustine says (Gen. ad lit. ii, 8).
