27. My sheep hear my voice, and I know them, and they follow me.
28. And I give to them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
30. I and my Father are one."
AUG. He saw that they were persons predestinated to eternal death, and not those for whom He had bought eternal life, at the price of His blood. The sheep believe, and follow the Shepherd.
THEOPHYL. After He had said, You are not of My sheep, He exhorts them to become such: My sheep hear My voice.
ALCUIN. i.e. Obey My precepts from the heart. And I know them, and they follow Me, here by walking in gentleness and innocence, hereafter by entering the joys of eternal life.
And I give to them eternal life.
AUG. This is the pasture of which He spoke before And shall find pasture. Eternal life is called a goodly pasture: the grass thereof wither not, all is spread with verdure. But these cavilers thought only of this present life. And they shall not perish eternally; as if to say, you shall perish eternally, because you are not of My sheep.
THEOPHYL. But how then did Judas perish? Because he did not continue to the end. Christ speaks of them who persevere. If any sheep is separated from the flock, and wanders from the Shepherd, it incurs danger immediately.
AUG. And He adds why they do not perish: Neither shall any man pluck them out of My hand. Of those sheep of which it is said, The Lord knows them that are His, the wolf robs none, the thief takes none, the robber kills none. Christ is confident of their safety; and He knows what He gave up for them.
HILARY. This is the speech of conscious power. Yet to show, that though of the Divine nature He has His nativity from God, He adds, My Father which gave Me them is greater than all. He does not conceal His birth from the Father, but proclaims it. For that which He received from the Father, He received in that He was born from Him. He received it in the birth itself, not after it; though He was born when He received it.
AUG. The Son, born from everlasting of the Father, God from God, has not equality with the Father by growth, but by birth. This is that greater than all which the Father gave Him b; viz. to be His Word, to be His Only-Begotten Son, to be the brightness of His light.
Wherefore no man takes His sheep out of His hand, any more than from His Father's hand: And no man is able to pluck them out of My Father's hand. If by hand we understand power, the power of the Father and the Son is one, even as Their divinity is one. If we understand the Son, the Son is the hand of the Father, not in a bodily sense, as if God the Father had limbs, but as being He by Whom all things were made.
Men often call other men hands, when they make use of them for any purpose. And sometimes a man's work is itself called his hand, because made by his hand; as when a man is said to know his own hand, when be recognizes his own handwriting. In this place, however, hand signifies power. If we take it for Son, we shall be in danger of imagining that if the Father has a hand, and that hand is His Son, the Son must have a Son too.
HILARY. The hand of the Son is spoken of as the hand of the Father, to let you see, by a bodily representation, that both have the same nature, that the nature and virtue of the Father is in the Son also.
CHRYS. Then that you may not suppose that the Father's power protects the sheep, while He is Himself too weak to do so, He adds, I and My Father are one.
AUG. Mark both those words, one and are, and you will be delivered from Scylla and Charybdis. In that He says, one the Arian, in we are the Sabellian, is answered. There are both Father and Son. And if one, then there is no difference of persons between them.
AUG. We are one. What He is, that am I, in respect of essence, not of relation.
HILARY. The heretics, since they cannot gainsay these words, endeavor by an impious lie to explain them away. They maintain that this unity is unanimity only; a unity of will, not of nature, i.e. that the two are one, not in that they are the same, but in that they will the same. But they are one, not by any economy merely, but by the nativity of the Son's nature, since there is no falling off of the Father's divinity in begetting Him.
They are one whilst the sheep that are not plucked out of the Son's hand, are not plucked out of the Father's hand: whilst in Him working, the Father works; whilst He is in the Father, and the Father in Him. This unity, not creation but nativity, not will but power, not unanimity but nature accomplishes.
But we deny not therefore the unanimity of the Father and Son; for the heretics, because we refuse to admit concord in the place of unity, accuse us of making a disagreement between the Father and Son. We deny not unanimity, but we place it on the ground of unity. The Father and Son are one in respect of nature, honor, and virtue: and the same nature cannot will different things.
