Verily, verily, I say unto you, That you shall weep and lament, but the world shall rejoice: and you shall be sorrowful, but your sorrow shall be turned into joy.
All Commentaries on John 16:20 Go To John 16
Cyril of Alexandria
AD 444
As then they were thirsting for information and sought to know more exactly the meaning of His words, He gives a clearer exposition of His Passion, and vouchsafes them the foreknowledge of the sufferings that He was about to undergo to their great profit. It was not in order that He might engender in them premature alarm that He deemed it meet to give them this explanation beforehand, but in order that, forearmed by their knowledge, they might perchance be found more courageous to withstand the terror that would assail them. For that of which the advent is expected is milder in its approach than that which is wholly unlooked for. When then you who are truly Mine and united to Me by your love towards Me shall behold your Guide and Master undergoing the brunt of the madness of the Jews, their insults and outrages, and all that their mad frenzy will prompt, then, indeed, ye shall weep and lament, but the world shall rejoice; that is, those who are not minded to follow God's Will, but are, as it were, enchained by worldly lusts. He refers also to the vulgar herd of Jewish rabble, as well as the impious band of enemies of God who had secured the lead among them, namely, the Scribes and Pharisees, who made jests at the trials our Saviour had to endure, and raised many cries to their own damnation, at one time saying, If Thou art the Son of God come down now from the cross, and we will believe Thee: and at another, Thou that destroyest the temple and buildest it in three days, save Thyself----for such will be the foul utterances of the blasphemous tongue of the Jews. But while the men of the world would be of this mind, and such will be their deeds and cries, "you will mourn;" but not for long will you have this suffering to endure, for your sorrow will be turned into joy. For I shall live again, and will wholly remove the cause of your despondency, and I will comfort the mourners, and will renew in them a good courage that will be eternal and without end. For the joy of the Saints ceaseth not. For Christ is alive for evermore, and through Him the bonds of death are loosed for all mankind. It is perhaps, too, not impertinent to reflect that the worldly will contrariwise be doomed to a fate of endless misery. For if, when Christ died after the flesh, those who were truly His mourned, but the world rejoiced at His Passion; and if, when death and corruption were rendered powerless by the Resurrection of our Saviour Christ from the dead, the mourning of the Saints was turned into joy, surely in like manner also the joy of the worldly-minded will be lost in sorrow.
