John Chrysostom

At the first He said, Whither I go ye shall come; but as this was a long time off, He promises them the Spirit in the interval. And as they knew not what that was, He promises them that they most desired, His own presence, I will come to you: but intimates at the same time that they are not to look for the same kind of presence over again: Yet a little while, and the world seeth Me no more: as if He said, I will come to you, but not to live with you every day as I did before. …

Catena Aurea by Aquinas ↗

Cyril of Alexandria

Of necessity our Lord Jesus the Christ at this point finishes the discourse touching the Holy and Consubstantial Trinity. For He has already shown before, setting forth both words and facts for assurance unto them that love Him, both that He is in His nature God and is begotten of God the Father, and is of equal might and like mind with Him. For to this end He also at one time said: What I speak, I speak not from Myself; and at another time again: If I do not the works of My Father, believe Me not. …

Commentary on the Gospel of John, Book 9 ↗

Theophylact of Ohrid

"Do not be afraid," He says, "that I said to you 'I will send another Comforter.' Do not think that you will no longer see Me. For I will not depart from you forever. I will come and will not leave you orphans." Since at the beginning of the discourse He called them children, He now fittingly says "I will not leave you orphans."

Commentary on John ↗

Augustine of Hippo

After the promise of the Holy Spirit, lest any should suppose that the Lord was to give Him, as it were, in place of Himself, in any such way as that He Himself would not likewise be with them, He added the words: "I will not leave you orphans; I will come to you." Orphani [Greek] are pupilli [parentless children] in Latin. The one is the Greek, the other the Latin name of the same thing: for in the psalm where we read, "Thou art the helper of the fatherless" [in the Latin version, pupillo], the Greek has orphano. …

Tractates on John 75 ↗

Hilary of Poitiers

Now how it is that we are in Him through the sacrament of the flesh and blood bestowed upon us, He Himself testifies, saying, "And the world will no longer see Me, but ye shall see Me; because I live ye shall live also; because I am in My Father, and ye in Me, and I in you." If He wished to indicate a mere unity of will, why did He set forth a kind of gradation and sequence in the completion of the unity, unless it were that, since He was in the Father through the nature of Deity, and we on the contrary in Him through His birth in …

On the Trinity, Book 8, Section 15 ↗

Thomas Aquinas

Above, our Lord promised that the Holy Spirit would be our Consoler. But because the apostles had not risen very high in their knowledge of the Holy Spirit, and their attention was absorbed by the presence of Christ, this consolation seemed small to them. Thus, in this part, our Lord promises, first, that he will return; secondly, his own gifts (v 25). Concerning the first, he promises then that he will return; and then he gives the reason (v 21); thirdly, he answers a question for one of the disciples (v 22). …
