Augustine of Hippo
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.
(Tract. lxxiv. 5) To be in a place is prior to dwelling. Be in you, is the explanation of dwell with you: i. e. shews that the latter means not that He is seen, but that He is known, He must be in us, that the knowledge of Him may be in us. We see the Holy Ghost then in us, in our consciences.
