19: The Incarnation
from THE CREED OF THE COUNCIL OF TOLEDO OF THE YEAR 400 [AND 447]
We believe in one true God, Father, and Son and Holy Spirit, maker of the visible and the invisible, by whom were created all things in heaven and on earth. This God alone and this Trinity alone is of divine name [divine substance]. The Father is not [himself] the Son, but has the Son, who is not the Father. The Son is not the Father, but the Son is of God by nature [is of the Father’s nature]. The Spirit is also the Paraclete, who is himself neither the Father, nor the Son, but proceeds from the Father [proceeding from the Father and the Son]. Therefore the Father is unbegotten, the Son is begotten, the Paraclete is not begotten, but proceeding from the Father [and the Son]. The Father is he whose words were heard from the heavens: This is my beloved Son, in whom I am well pleased, hear ye him. [Matt. 17:5;2 Peter 1:17. Cf- Matt. 3:17]. The Son is he who says: I came forth from the Father, and am come into the world [cf. John 16:28]. The Paraclete himself [the Spirit] is he, concerning whom the Son says: Unless I go to the Father, the Paraclete will not come to you [John 16:17]. This Trinity, though distinct in persons, is one substance [united], virtue, power, majesty [in virtue and in power and in majesty] indivisible, not different. [We believe] there is no divine nature except that [this], either of angel or of spirit or of any virtue, which is believed to be God.
Catena Aurea
29. His disciples said to him, Lo, now you speak plainly, and speak no proverb. 30. Now are we sure that you know all things, and need not that any man should ask you; by this we believe that you came forth from God. 31. Jesus answered them, Do you now believe? 32. Behold, the hour comes, yea, is now come, that you shall be scattered, every man to his own, and shall leave me alone; and yet I am not alone, because the Father is with me. 33. These things I have spoken to you, that in me you might have peace. In the world you shall have tribulation; but be of good cheer: I have overcome the world.
CHRYS. The disciples were so refreshed with the thought of being in favor with the Father, that they say they are sure He knows all things: His disciples said to Him, Now you speak plainly, and speak no proverb.
AUG. But why do they say so, when the hour in which He was to speak without proverbs was yet future, and only promised? Because, our Lord’s communications still continuing proverbs to them, they are so far from understanding them, that they do not even understand their not understanding them.
CHRYS. But since His answer met what was in their minds, they add, Now we are sure that you know all things. See how imperfect they yet were, after so many and great things now at last to say, Now we are sure &c. saying it too as if they were conferring a favor. And need not that any man should ask you, i.e. you know what offends us, before we tell You, and you have relieved us by saying that the Father loves us.
AUG. Why this remark? To one Who knew all things, instead of saying, you need not that any man should ask You; it would have been more appropriate to have said, you need not to ask any man; yet we know that both of these were done, viz. that our Lord both asked questions, and was asked. But this is soon explained; for both were for the benefit, not of Himself, but of those whom He asked questions of, or by whom He was asked. He asked questions of men not in order to learn Himself, but to teach them: and in the case of those who asked questions of Him, such questions were necessary to them in order to gain the knowledge they wanted; but they were not necessary to Him to tell Him what that was, because He knew the wish of the inquirer, before the question was put. Thus to know men’s thoughts beforehand was no great thing for the Lord, but to the minds of babes it was a great thing: By this we know that you came forth from God.
HILARY. They believe that He came forth from God, because He does the works of God. For whereas our Lord had said both, I came forth from the Father, and, I am come into the world from the Father, they testified no wonder at the latter words, I am come into the world, which they had often heard before. But their reply shows a belief in and appreciation of the former, I came forth from the Father. And they notice this in their reply: By this we believe that you came forth from God; not adding, and are come into the world, for they knew already that He was sent from God, but had not yet received the doctrine of His eternal generation. That unutterable doctrine they now began to see for the first time in consequence of these words, and therefore reply that He spoke no longer in parables. For God is not born from God after the manner of human birth; His is a coming forth from, rather than a birth from, God. He is one from one; not a portion, not a defection, not a diminution, not a derivation, not a pretension, not a passion, but the birth of living nature from living nature. He is God coming forth from God, not a creature appointed to the name of God; He did not begin to be from nothing, but He came forth from an abiding nature. To come forth has the signification of birth, not of beginning.
AUG. Lastly, He reminds them of their weak tender age in respect of the inner man. Jesus answered them, Do you now believe?
BEDE. Which can be understood in two ways, either as reproaching or affirming. If the former, the meaning is, you have awaked somewhat late to belief, for behold the hour comes, yea is now come, that you shall be scattered every man to his home. If the latter, it is, That which you believe is true, but behold the hour comes, &c.
AUG. For they did not only with their bodies leave His body, when He was taken, but with their minds the faith.
CHRYS. You shall be scattered; i.e. when I am betrayed, fear shall so possess you, that you will not be able even to take to flight together. But I shall suffer no harm in consequence: And yet I am not alone, because the Father is with Me.
AUG. He wishes to advance them so far as to understand that He had not separated from the Father because He had come forth from the Father.
CHRYS. These things have I said to you, that you might have peace; i.e. that you may not reject Me from your minds. For not only when I am taken shall you suffer tribulation, but so long as you are in the world: In the world you shall have tribulation.
GREG. As if He said, Have Me within you to comfort you, because you will have the world without you.
AUG. The tribulation of which He speaks was to commence thus, i.e. in every one being scattered to his home, but was not to continue so. For in saying, And leave Me alone, He does not mean this to apply to them in their sufferings after His ascension. They were not to desert Him then, but to abide and have peace in Him. Wherefore He adds, Be of good cheer.
CHRYS. i.e. raise up your spirits again; when the Master is victorious, the disciples should not be dejected; I have overcome the world.
AUG. When the Holy Spirit was given them, they were of good cheer, and, in His strength, victorious. For He would not have overcome the world, had the world overcome His members. When He says, These things have I spoken to you, that in Me you might have peace, He refers not only to what He has just said, but to what He had said all along, either from the time that He first had disciples, or since the supper, when He began this long and wonderful discourse. He declares this to be the object of His whole discourse, viz. that in Him they might have peace. And this peace shall have no end, but is itself the end of every pious action and intention.
