John 14:16

(Didym. De Spiritu Sancto.) But the Holy Ghost was another Comforter: differing not in nature, but in operation. For whereas our Saviour in His office of Mediator, and of Messenger, and as High Priest, made supplication for our sins; the Holy Ghost is a Comforter in another sense, i. e. as consoling our griefs. But do not infer from the different operations of the Son and the Spirit, a difference of nature. For in other places we find the Holy Spirit performing the office of intercessor with the Father, as, The Spirit Himself intercedeth for us. (Rom. 8:26) And the Saviour, on the other hand, pours consolation into those hearts that need it: as in Maccabees, He strengthened those of the people that were brought low. (1 Macc. 14:15)

(Hom. lxxiv) But what had He more than the Apostles, if He could only ask the Father to give others the Spirit? The Apostles did this often even without praying. (Hom. lxxv. 1) When He had cleansed His disciples by the sacrifice of His passion, and their sins were remitted, and they were sent forth to dangers and trials, it was necessary that they should receive the Holy Spirit abundantly. But they were made to wait some time for this gift, in order that they might feel the want of it, and so be the more grateful for it when it came.

"And I will ask the Father, and He shall give you another Comforter." Again His speech is one of condescension. For since it was probable, that they not yet knowing Him would eagerly seek His society, His discourse, His presence in the flesh, and would admit of no consolation when He was absent, what saith He? "I will ask the Father, and He shall give you another Comforter," that is, "Another like unto Me." Let those be ashamed who have the disease of Sabellius, who hold not the fitting opinion concerning the Spirit. For the marvel of this discourse is this, that it hath stricken down contradictory heresies with the same blow. For by saying "another," He showeth the difference of Person, and by "Paraclete," the connection of Substance. But why said He, "I will ask the Father"? Because had He said, "I will send Him," they would not have so much believed and now the object is that He should be believed. For afterwards He declares that He Himself sendeth Him, saying, "Receive ye the Holy Ghost"; but in this place He telleth them that He asketh the Father, so as to render His discourse credible to them.

"He remaineth with you." This showeth that even after death It departeth not.

But when He says, "I will ask the Father, and He shall give you another Paraclete," He intimates that He Himself is also a paraclete. For paraclete is in Latin called advocatus (advocate); and it is said of Christ, "We have an advocate with the Father, Jesus Christ the righteous." But He said that the world could not receive the Holy Spirit, in much the same sense as it is also said, "The minding of the flesh is enmity against God: for it is not subject to the law of God; neither indeed can be;" just as if we were to say, Unrighteousness cannot be righteous. For in speaking in this passage of the world, He refers to those who love the world; and such a love is not of the Father. And thus the love of this world, which gives us enough to do to weaken and destroy its power within us, is in direct opposition to the love of God, which is shed abroad in our hearts by the Holy Spirit who is given unto us. "The world," therefore, "cannot receive Him, because it seeth Him not, neither knoweth Him." For worldly love possesseth not those invisible eyes, whereby, save in an invisible way, the Holy Spirit cannot be seen.
