John Chrysostom, on Heb 12:14

“Follow peace with all men, and holiness: without which no man shall see God.”

“"Follow peace with all men, and holiness, without which no man shall see the Lord." What he also said above, "Not forsaking the assembling of yourselves together" (c. x. 25), he hints at in this place also. For nothing so especially makes persons easily vanquished and subdued in temptations, as isolation. For, tell me, scatter a phalanx in war, and the enemy will need no trouble, but will take them prisoners, coming on them separately, and thereby the more helpless. "Follow peace with all men, and holiness" (he says). Therefore with the evil-doers as well? "If it be possible," he says, "as much as lieth in you, live peaceably with all men." (Rom. xii. 18.) For thy part (he means) "live peaceably," doing no harm to religion: but in whatever thou art ill-treated, bear it nobly. For the bearing with evil is a great weapon in trials. Thus Christ also made His disciples strong by saying, "Behold I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves," (Matt. x. 16.) What dost Thou say? Are we "among wolves," and dost Thou bid us to be "as sheep," and "as doves"? Yea, He says. For nothing so shames him that is doing us evil, as bearing nobly the things which are brought upon us: and not avenging ourselves either by word or by deed. This both makes us more philosophical ourselves and procures a greater reward, and also benefits them. But has such an one been insolent? Do thou bless him. See how much thou wilt gain from this: thou hast quenched the evil, thou hast procured to thyself a reward, thou hast made him ashamed, and thou hast suffered nothing serious.”
