A dreadful thing is envy, beloved, a dreadful thing and a pernicious, to the enviers, not to the envied. For it harms and wastes them first, like some mortal venom deeply seated in their souls; and if by chance it injure its objects, the harm it does is small and trifling, and such as brings greater gain than loss. Indeed not in the case of envy only, but in every other, it is not he that has suffered, but he that has done the wrong, who receives injury. For had not this been so, Paul would not have enjoined the disciples rather to endure wrong than to inflict it, when he says, “Why do ye not rather take wrong? Why do ye not rather suffer yourselves to be defrauded?” ( 1 Cor. vi. 7 .) Well he knew, that destruction ever follows, not the injured party, but the injuring. All this I have said, by reason of the envy of the Jews. Because those who had flocked from the cities to John, and had condemned their own sins, and caused themselves to be baptized, repenting as it were after Baptism, send to ask him, “Who art thou?” Of a truth they were the offspring of vipers, serpents, and even worse if possible than this. O evil and adulterous and perverse generation, after having been baptized, do ye then become vainly curious, and question about the Baptist? What folly can be greater than this of yours? How was it that ye came forth? that ye confessed your sins, that ye ran to the Baptist? How was it that you asked him what you must do? when in all this you were acting unreasonably, since you knew not the principle and purpose of his coming. Yet of this the blessed John said nothing, nor does he charge or reproach them with it, but answers them with all gentleness.
