Remigius of Auxerre
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.
It may also be referred in particular to the rich man, who seemed to be first, by his fulfilment of the precepts of the Law, but was made last by his preferring his worldly substance to God. The holy Apostles seemed to be last, but by leaving all they were made first by the grace of humility. There are many who having entered upon good works, fall therefrom, and from having been first, become last.
