And Sanballat the Horonite, etc., heard. And the heretics are grieved, and all the enemies of the Church are saddened whenever they see any elected persons working for the sake of the Catholic faith or for the correction of customs, by which the walls of the Church are to be renewed. Indeed, the diversity of souls and matters is to be noted, for it was said above that those who remained from captivity in Judea were in great affliction and reproach; but also Nehemiah led a long fast with weeping and prayers because the walls of Jerusalem were broken down, and its gates were burned with fire. And now, on the contrary, the enemies of that same holy city are in great affliction and are grieved because its buildings are to be restored, and at the same time, the citizens understand that they are to be lifted from the insults of their enemies. From this, it is to be gathered that even in this life, the sentence of the Lord can be fulfilled; He who said: Amen, amen, I say to you, that you will weep and lament, but the world will rejoice; you will be sorrowful, but your sorrow will turn into joy (John 16). For as the world that rejoiced is weeping, the sorrow of the righteous will be turned into joy when the holy affairs of the Church are seen to grow, and those who had strayed by sinning are recognized to return to it by repenting.
