Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.

Nevertheless I tell you the truth, it is expedient for you that I go away. (1.) S. Chrysostom (Hom. lxxvii.) explains it thus, "I say not this to please you, but though you will be made more sorrowful, you must hear what is expedient. Ye indeed would wish Me to be near, but utility demands the contrary. But it is the duty of one who loves, when he learns the utility, not to allow his beloved ones to be deprived of it." And S. Cyril (x39) almost in the same words, "I perceive that ye are affected with great sorrow, because I have resolved to go away. And that too, not unreasonably, especially when ye hear that great tribulations will befall you. But since utility is to be preferred to what is pleasant, I will make known to you the truth."
Christ does not here oppose "truth" to grace, but to sorrow, and makes truth refer to the consolation of the Apostles. For He says this to take away their sorrow by the joyful message of consolation. Ye are sorrowful (He would say) at My departure, as if it were your greatest loss. But be assured, both that ye have sorrow, and that it is in truth expedient for you that I go away. For My departure to the Father will be to you of the greatest benefit. For I will send from thence the Holy Spirit on you, Who will fill you with all virtue and strength. And therefore My departure will not only be to your highest profit, but even to your pleasure, as you will experience at Pentecost. Whence He adds, For if I go not away, the Comforter (your consoler and encourager) will not come unto you; but if I depart I will send Him unto you (see above and chap. vii39). For the disciples, as children with their mother, and chickens with the hen, being too much accustomed to converse with Christ as a Prayer of Manasseh , and to His corporeal presence, could not understand the Holy Spirit and His spiritual gifts. And Christ accordingly withdrew from them, that being weaned from Him, and their minds wholly fixed on the Holy Spirit, they might be raised by Him to heroic deeds, by which they would convert the whole world. And accordingly the Holy Spirit coming on them at Pentecost, made them masters instead of disciples, and created them teachers of the whole world. (See S. Augustine, in loc, and S. Gregory, Moral. viii33.) The Holy Spirit is here appositely called the Paraclete, to signify that He would amply console the disciples, who were sad at Christ"s departure, and would fill them with every joy. Hence S. Chrysostom (Hom. lxxvii.) proves against Macedonius that the Holy Spirit is truly God; for were He not the Creator, but merely a creature, how would it be expedient that Christ, on account of His coming, should leave the disciples, being their Creator and God? Again, lest it should be thought that the Holy Spirit is the same with the Song of Solomon , Christ adds, "I will send Him unto you," for the Sender is really and personally distinguished from the Sent. And it is signified also that the Holy Spirit proceeds alike from the Father and the Son. For in the Holy Trinity whatever Person sends another Person produces It, that Isaiah , begets or breathes it, as the Father sending the Song of Solomon , begets Him also, and He likewise together with the Song of Solomon , by sending the Holy Spirit, also breathes Him forth.
