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.
This His floor, to wit, the Church, the Lord cleanses in this life, both when by the sentence of the Priests the bad are put out of the Church, and when they are cut off by death.
