Hilary of Poitiers
Catena Aurea · Matthäusevangelium 24
But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only. But as the days of Noe were, so shall also the coming of the Son of man be. For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark, And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be. Then shall two be in the field; the one shall be taken, and the other left. Two women shall be grinding at the mill; the one shall be taken, and the other left.
Or, the two in the field, are the two people of believers and unbelievers, whom the day of the Lord shall overtake, as it were in the labours of this life. And they shall be separated, one being taken and the other left; this shews the separation that shall be between believers and unbelievers; when God’s wrath is kindled, the saints shall be gathered into His garner, and the unbelievers shall be left as fuel for the fire from heaven. The same is the account to be given of that, Two shall be grinding at the mill. The mill is the work of the Law, but as some of the Jews believed through the Apostles, so some shall believe through Elias, and be justified through faith; and one part shall be taken through this same faith of good works, theother part shall be left unfruitful in the work of the Law, grinding in vain, and never to produce the bread of heavenly food.
