Augustine of Hippo
Catena Aurea · Johannesevangelium 16
But now I go my way to him that sent me; and none of you asketh me, Whither goest thou? But because I have said these tilings unto you, sorrow hath filled your heart. Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. And when he is come, he will reprove the world of sin, and of righteousness, and of judgment: Of sin, because they believe not on me; Of righteousness, because I go to my Father, and ye see me no more; Of judgment, because the prince of this world is judged.
(Tr. xciv) Or whereas they had asked Him above, whither He was going, and He had replied that He was going whither they would not come; now He promises that He will go in such a way that no one will ask Him whither He goeth: and none of you asketh Me, Whither goest Thou? Going up to heaven, they questioned Him not in words, but followed with their eyes. But our Lord saw what effect His words would produce upon their minds. Not having yet that inward consolation which the Holy Ghost was to impart, they were afraid to lose the outward presence of Christ, and so, when they could no longer doubt from His own words that they were going to lose Him, their human affections were saddened, for the loss of their visible object. Wherefore it follows; But because I have said these things unto you, sorrow hath filled your heart. But He knew that it would be for their good, forasmuch as that inward sight wherewith the Holy Ghost would console them, was the better one: Nevertheless I tell you the truth; It is expedient for you that I go away.
