Think not that I am come to send peace on earth: I came not to send peace, but a sword.
Read Chapter 10
George Leo Haydock
I came not to send That is, dissension and war, in order that the false peace of sinners may be destroyed, and that those who follow me, may differ in morals and affections from the followers of this world. The sword, therefore, is the gospel, which separates those parents who remain in infidelity (Menochius)
It must be observed, that the gospel does not necessarily of itself produce dissensions amongst men, but that Christ foresaw, from the depravity of man's heart, that dissensions would follow the propagation of the gospel. The blame of this, however, does not attach to the gospel itself, since those who embrace it, after their conversion sought more than ever to keep peace with all men, even with their most bitter persecutors; whilst those who rejected the gospel, forgetting even the ties of kindred, persecuted even to death the followers of Christ.

How then did He enjoin them to pronounce peace on entering into each house? And again, how did the angels say, Glory to God in the highest, and on earth peace? Luke 2:14 And how came all the prophets too to publish it for good tidings? Because this more than anything is peace, when the diseased is cut off, when the mutinous is removed. For thus it is possible for Heaven to be united to earth. Since the physician too in this way preserves the rest of the body, when he amputates the incurable part; and the general, when he has brought to a separation them that were agreed in mischief.

What sort of peace is it that Jesus asks them to pronounce upon entering each house? And what kind of peace is it of which the angels sing, “Glory to God in the highest and on earth peace”? And if Jesus came not to bring peace, why did all the prophets publish peace as good news? Because this more than anything is peace: when the disease is removed. This is peace: when the cancer is cut away. Only with such radical surgery is it possible for heaven to be reunited to earth. Only in this way does the physician preserve the healthy tissue of the body. The incurable part must be amputated. Only in this way does the military commander preserve the peace: by cutting off those in rebellion. Thus it was also in the case of the tower of Babel, that their evil peace was ended by their good discord. Peace therefore was accomplished. The Gospel of Matthew, Homily
