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 is this difference between the chaff and the tares, that the chaff is produced of the same seed as the wheat, but the tares from one of another kind. The chaff therefore are those who enjoy the sacraments of the faith, but are not solid; the tares are those who in profession as well as in works are separated from the lot of the good.
