John 14:31

"Arise, let us go hence." "But why, tell me? Did he not know the hour at which Judas would come upon Him? Or perhaps He feared lest he should come and seize them, and lest the plotters should be upon him before he had furnished his most excellent teaching." Away with the thought! these things are far from His dignity. "If then He did not fear, why did He remove them, and then after finishing His discourse lead them into a garden known to Judas? And even had Judas come, could He not have blinded their eyes, as He also did when the traitor was not present? Why did He remove them?" He alloweth the disciples a little breathing time. For it was likely that they, as being in a conspicuous place, would tremble and fear, both on the account of the time and the place, (for it was the depth of night,) and would not give heed to His words, but would be continually turning about, and imagining that they heard those who were to set upon them; and that more especially when their Master's speech made them expect evil. For, "yet a little while," He saith, "and I am not with you," and, "the ruler of this world cometh." Since now when they heard these and the like words they were troubled, as though they should certainly be taken immediately, He leadeth them to another place, in order that thinking themselves in safety, they might listen to Him without fear. For they were about to hear lofty doctrines.

But how, it might be asked, canst thou die, if thou hast no sin: He answers, But that the world may know that I love the Father, and as the Father gave Me commandment, even so I do. Arise, let us go hence. He had been sitting at table with them all this time. Let us go: i. e. to the place, where He, Who had done nothing to deserve death, was to be delivered to death. But He had a commandment from His Father to die. (contr. Serm. Arrian. c. xi.) That the Son is obedient to the will and commandment of the Father, no more shows a difference in the two, than it would in a human father and son. But over and above this comes the consideration that Christ is not only God, and as such equal to the Father, but also man, and as such inferior to the Father.

And, as if it were said to Him, Why, then, dost Thou die, if Thou hast no sin to merit the punishment of death? He immediately added, "But that the world may know that I love the Father, and as the Father gave me commandment, even so I do: arise, let us go hence." For He was sitting at table with those who were similarly occupied. But "let us go," He said, and whither, but to the place where He, who had nothing in Him deserving of death, was to be delivered up to death? But He had the Father's commandment to die, as the very One of whom it had been foretold, "Then I paid for that which I took not away;" and so appointed to pay death to the full, while owing it nothing, and to redeem us from the death that was our due. For Adam had seized on sin as a prey, when, deceived, he presumptuously stretched forth his hand to the tree, and attempted to invade the incommunicable name of that Godhead which was disallowed him, and with which the Son of God was endowed by nature, and not by robbery.
