Pseudo-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.
(Vict. Ant. e Cat. in Marc.) He then who has learned this, is bound zealously to confess Christ without shame. And this generation is called adulterous, because it has left God the true Bridegroom of the soul, and has refused to follow the doctrine of Christ, but has prostrated itself to the devil and taken up the seeds of impiety, for which reason also it is called sinful. Whosoever therefore amongst them has denied the kingdom of Christ, and the words of God revealed in the Gospel, shall receive a reward befitting His impiety, when He hears in the second advent, I know you not. (Matt. 7:23)
