Him, then, Whom the Apostle called the Spirit of Life, the Lord in the Gospel named the Paraclete, and the Spirit of Truth, as you find: “And I will ask the Father, and He will give you another Comforter [Paraclete], that He may be with you for ever, even the Spirit of Truth, Whom this world cannot receive; because it seeth Him not, neither knoweth Him.” S. John xiv. 16, 17. You have, then, the Paraclete Spirit, called also the Spirit of Truth, and the invisible Spirit. How, then, do some think that the Son is visible in His Divine Nature, when the world cannot see even the Spirit?
