John Chrysostom
Catena Aurea · Matthäusevangelium 19
Then answered Peter and said unto him, Behold, we have forsaken all, and followed thee; what shall we have therefore? And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel. And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name’s sake, shall receive an hundred fold, and shall inherit everlasting life. But many that are first shall be last; and the last shall be first.
(Hom. lxiv.) What was this all, O blessed Peter? The reeds, your net, and boat. But this he says, not to call to mind his own magnanimity, but in order to propose the case of the multitude of poor. A poor man might have said, If I have nought, I cannot become perfect. Peter therefore puts this question that you, poor man, may learn that you are in nothing behind. For he had already received the kingdom of heaven, and therefore secure of what was already there, he now asks for the whole world. And see how carefully he frames his question after Christ’s requirements: Christ required two things of a rich man, to give what he had to the poor, and to follow Him; wherefore he adds, and have followed thee.
