John Chrysostom
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.
(Hom. lxxviii) As if He said, Though your grief be ever so great, ye must hear how that it is profitable for you that I go away. What the profit is He then shews: For if I go not away, the Comforter will not come unto you.
