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. xcv. 2) The world is reproved of sin, because it believes not in Christ, and reproved of righteousness, the righteousness of those that believe. The very contrast of the believing, is the censure of the unbelieving. Of righteousness, because I go to the Father: as it is the common objection of unbelievers, How can we believe what we do not see? so the righteousness of believers lies in this, Because I go to the Father, and ye see Me no more. For blessed are they which see not, and believe. The faith even of those who saw Christ is praised, not because they believed what they saw, i. e. the Son of man, but because they believed what they saw not, i. e. the Son of God. And when the form of the servant was withdrawn from their sight altogether, then only was fulfilled in completeness the text, The just liveth by faith. (Heb. 10:38) It will be your righteousness then, of which the world will be reproved, that ye shall believe in Me, not seeing Me. And when ye shall see Me, ye shall see Me as I shall be, not as I am now with you, i. e. ye shall not see Me mortal, but everlasting. For in saying, Ye see Me no more (jam non videbitis me Vulg.), He means that they should see Him no more for ever.
