John Chrysostom
Catena Aurea · Johannesevangelium 14
If ye love me, keep my commandments. And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
(Hom. lxxv. 1) That He may abide with you for ever. The Spirit does not depart even at death. He intimates too that the Holy Ghost will not suffer death, or go away, as He has done. But that the mention of the Comforter might not lead them to expect another incarnation, a Comforter to be seen with the eye, He adds, Even the Spirit of truth, Whom the world cannot receive, because it seeth Him not, neither knoweth Him.
