Tractates on the Gospel of John

⁴ But further, lest any should imagine that the Father and Son only, without the Holy Spirit, make their abode with those that love Them, let him recall what was said above of the Holy Spirit, “Whom the world cannot receive, because it sees Him not, neither knows Him: but you shall know Him; for He shall dwell with you, and shall be in you”. Here you see that, along with the Father and the Son, the Holy Spirit also takes up His abode in the saints; that is to say, within them, as God in His temple.

The triune God, Father, and Son, and Holy Spirit, come to us while we are coming to Them: They come with help, we come with obedience; They come to enlighten, we to behold; They come to fill, we to contain: that our vision of Them may not be external, but inward; and Their abiding in us may not be transitory, but eternal. The Son does not manifest Himself in such a way as this to the world: for the world is spoken of in the passage before us as those, of whom He immediately adds, “He that loves me not, keeps not my sayings.”

These are such as never see the Father and the Holy Spirit: and see the Son for a little while, not to their attainment of bliss, but to their condemnation; and even Him, not in the form of God, wherein He is equally invisible with the Father and the Holy Spirit, but in human form, in which it was His will to be an object of contempt in suffering, but of terror in judging the world.
