Catena Aurea on John 14:27–31: Augustine of Hippo

i. e. the devil; the prince of sinners, not of creatures; as the Apostle saith, Against the rulers of this world. (Eph. 6:12) Or, as He immediately adds by way of explanation, this darkness, meaning, the ungodly. And hath nothing in Me. God had no sin as God, nor had His flesh contracted it by a sinful birth, being born of the Virgin. 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.
