FOURTH ARTICLE: WHETHER CHRIST HAD ANY ACQUIRED KNOWLEDGE

State of the question. This article concerns the habit of experimental knowledge acquired by the intellect through species abstracted from phantasms, or obtained gradually by individual acts.

The difficulty is: (1) If Christ had this knowledge, then He did not have it perfectly, because He never studied. (2) This acquired knowledge seems superfluous if Christ already had directly infused knowledge of created things, and especially if He already had accidentally infused knowledge of sensible things.

Conclusion. Christ had knowledge that is essentially capable of being acquired, and that was also actually acquired by Him.

Scriptural proof. St. Paul says: "Whereas, indeed, He was the Son of God, He learned obedience by the things which He suffered,"[1210] that is, by what He experienced. Farther on,[1211] St. Thomas quotes the following Gospel text: "Jesus advanced in wisdom and age, and grace with God and men,"[1212] which He explains as resulting from an increase of acquired knowledge.

St. Thomas himself admits in the present article that he corrects what he wrote in an earlier work on this subject,[1213] in which he taught that Christ had knowledge that is essentially acquirable, yet it was not acquired by His own acts, but was accidentally infused, as in the case of Adam who was created completely developed. But now St. Thomas maintains that, as it was fitting for Christ's body to develop gradually, so also it was proper for His soul to advance gradually in the knowledge of natural things. Hence the Evangelist says: "Jesus advanced in wisdom and age."[1214]

Theological proof. Nothing that God planted in our nature was wanting to the human nature of Christ, among which is the active intellect or the connatural active principle of intellectual knowledge.

But the active intellect would have been useless in Christ, lacking in its own and special operation, if He did not have knowledge acquired by His own acts by abstracting intelligible species from phantasms.

Therefore Christ had this knowledge.

Objection. Scotus maintains that the active intellect neither was useless in Adam, nor is it so in the blessed. The purpose of the active intellect is not only to abstract species, but it also serves the purpose of illustrating principles to be made use of in conclusions.

Reply. The Thomists point out that there is a difference between Christ and Adam, who was created not as a child, but as fully developed, as there is a difference between Christ and disembodied spirits that no longer have the connatural mode of understanding by turning to phantasms. If Christ had not acquired knowledge by repeated acts of the intellect, His active intellect would have been useless, not absolutely so, but as regards its connatural mode of operating; for it would be deprived of that act to which it is entitled in such a state and at such a time.

Moreover, it was no imperfection for Christ that as a child He was deprived of speech, or that He was unable as yet to acquire perfect knowledge of things. He already had by the beatific knowledge superabundant cognition for the perfect knowledge of divine things and of other things in the Word. Therefore Christ in a certain sense progressed intellectually, but not morally.

The solution of the objections of this article confirms the reply of St. Thomas.

Reply to first objection. "It was more fitting for Christ to possess a knowledge acquired by discovery than by being taught", hence He acquired acquirable knowledge not by learning, but rather by discovery, by a consideration of nature and men.

Reply to second objection. "It behooved Christ's intellect to be also perfected with regard to phantasms," although it was already perfected by infused knowledge. For this is a new and connatural mode of knowing. Someone may already have certainty of knowledge by the gift of prophecy that death will come on a certain day; in another way, however, there is experimental knowledge of the moment of death.

Reply to third objection. There was also a distinction between this acquired knowledge and infused knowledge concerning sensible things, for this second kind of knowledge, coming as it does from on high, is not proportioned to phantasms. Thus he who sings the melody of a musical composition solely from memory, not having studied music, can afterward in another way know this melody by distinguishing the various parts and notes of the musical score, reading it even to the least detail. Previously he knew the musical composition as some general melody, but now he knows its parts and the way these are distinctly related to the whole.

Thus, then, it is the common teaching of theologians since the time of Peter Lombard, that there were three kinds of knowledge in Christ: the beatific, infused, and acquired knowledge.

Each particular knowledge must now be considered briefly.
