Remigius of Auxerre
Catena Aurea · Matthäusevangelium 3
I indeed baptize you with water unto repentance: but He that cometh after me is mightier than I, Whose shoes I am not worthy to bear: He shall baptize you with the Holy Ghost, and with fire: Whose fan is in His hand, and He will throughly purge His floor, and gather His wheat into the garner; but He will burn up the chaff with unquenchable fire.
There are five points in which Christ comes after John, His birth, preaching, baptism, death, and descent into hell. A beautiful expression is that, mightier than I, because he is mere man, the other is God and man.
