Jesus' two natures and omniscience

Was Jesus’ human nature omniscient? It seems not by this:

This human soul that the Son of God assumed is endowed with a true human knowledge. As such, this knowledge could not in itself be unlimited: It was exercised in the historical conditions of his existence in space and time. This is why the Son of God could, when he became man, “increase in wisdom and in stature, and in favor with God and man,” and would even have to inquire for himself about what one in the human condition can learn only from experience. This corresponded to the reality of his voluntary emptying of himself, taking “the form of a slave.” (CCC 472)

However if the divine nature was omniscient how would that manifest in a given moment? Walking around interacting with the physical world and people, how could a person have thoughts and be omniscient and ignorant simultaneously? In a given moment you either know about germ theory or you don’t.

Christ had both a Divine nature and a full human nature, consequently He had two intellects, one Divine and one human. With His Divine intellect, which is common to each of the Persons of the Trinity, He knew all things whatsoever. With His human intellect, He had three modes of knowing:

  1. Christ had the fullness of the Beatific Vision from the first moment of His conception, by virtue of this He knew all things which at any time were or will be actual, and all potentialities rooted in anything actual. But He did not know, via His human intellect, of those potentialities which have never been and will never be actualized, since this would be to know the full power of God, which is impossible for any created intellect.

  2. Christ had all knowledge which is either the object of human science or of divine revelation infused into His soul from the moment of His conception. He was able to make use of this knowledge both via discursive thought and without the mediation of discursive thought, and it is in this way that He was able to contemplate all the sins of humanity while He hung on the cross. This would include things like germ theory.

  3. Christ had acquired or experiential knowledge, which is what the CCC passage you quote refers to. This is the only mode of knowledge He had which was capable of increase. It increased by His experience, but not by being taught anything by others, since it would have been unfitting for Christ to have had a human teacher.

Obviously, these modes of knowing were not equal. Christ’s experiential knowledge encompassed only a subset of His infused knowledge, which likewise encompassed only a subset of his Beatific knowledge.

How do you square this with Mark 13:32?

That’s generally been held to refer to His infused knowledge. I.e. He was not sent to reveal that.
