Theophylact of Ohrid — as excerpted in the Catena Aurea on Mark 13:9-13

“And this He says, that on hearing it, they might prepare themselves to bear persecutions and ills with greater patience. Then He brings them consolation, saying, And ye shall be hated of all men for my name’s sake; for the being hated for Christ’s sake is a sufficient reason for suffering persecutions patiently,1 for it is not the punishment, but the cause, that makes the martyr. Again, that which follows is no small comfort amidst persecution: But he that shall endure unto the end, the same shall be saved.”
