Augustine of Hippo
Catena Aurea · Johannesevangelium 6
And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. But I said unto you, That ye also have seen me, and believe not. All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. For I came down from heaven, not to do mine own will, but the will of him that sent me. And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
(Tr. xxv. 15) This is the reason why He does not cast out those who come to Him. For I came down from heaven not to do Mine own will, but the will of Him that sent Me. The soul departed from God, because it was proud. Pride casts us out, humility restores us. When a physician in the treatment of a disease, cures certain outward symptoms, but not the cause which produces them, his cure is only temporary. So long as the cause remains, the disease may return. That the cause then of all diseases, i. e. pride, might be eradicated, the Son of God humbled Himself. Why art thou proud, O man? The Son of God humbled Himself for thee. It might shame thee, perhaps, to imitate a humble man; but imitate at least a humble God. And this is the proof of His humility: I came not to do Mine own will, but the will of Him that sent Me. Pride does its own will; humility the will of God.
