John Chrysostom
Catena Aurea · Markusevangelium 8
And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me. For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the Gospel’s, the same shall save it. For what shall it profit a man, if he shall gain the whole world, and lose his own soul? Or what shall a man give in exchange for his soul? Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels.
(ubi sup.) But He says not, a man should not spare himself, but what is more, that he should deny himself, as if he had nothing in common with himself, but face danger, and look upon such things as if another were suffering; and this is really to spare himself; for parents then most truly act kindly to their children, when they give them up to their masters, with an injunction not to spare them. Again, He shews the degree to which a man should deny himself, when He says, And take up his cross, by which He means, even to the most shameful death.
