Theophylact of Ohrid
Catena Aurea · Markusevangelium 10
Then Peter began to say unto him, Lo, we have left all, and have followed thee. And Jesus answered and said, Verily I say unto you, There is no man that hath left house, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my sake, and the Gospel’s, But he shall receive an hundredfold now in this time, houses, and brethren, and sisters, and mothers, and children, and lands, with persecutions; and in the world to come eternal life. But many that are first shall be last; and the last first.
Although Peter had left but few things, still he calls these his all; for even a few things keep us by the bond of affection, so that he shall be beatified who leaves a few things.
