Bede the Venerable
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.
(in Marc. 2, 36) Or else He says this, because in time of persecution, our life is to be laid aside, but in time of peace, our earthly desires are to be broken, which He implies when He says, For what shall it profit a man, &c. But we are often hindered by a habit of shamefacedness, from expressing with our voice the rectitude which we preserve in our hearts; and therefore it is added, For whosoever shall confess me and my words in this adulterous and sinful generation, him also shall the Son of man confess, when he cometh in the glory of his Father with the holy angels.
