Catena Aurea

BASIL. (non occ.) But they are mixed up with those who are worthy of the kingdom of heaven, as the chaff with the wheat. This is not however from consideration of their love of God and their neighbour, nor from their spiritual gifts or temporal blessings.

ORIGEN. Or, because without the wind the wheat and chaff cannot be separated, therefore He has the fan in His hand, which shews some to be chaff, some wheat; for when you were as the light chaff; (i. e. unbelieving,) temptation shewed you to be what you knew not; but when you shall bravely endure temptation, the temptation will not make you faithful and enduring, but it will bring to light the virtue which was hid in you.

GREGORY OF NYSSA. (non occ.) But it is well to know, that the treasures, which according to the promises are laid up for those who live honestly, are such as the words of man cannot express, as eye hath not seen, nor the ear heard, nor hath it entered into the heart of man to conceive. And the punishments which await sinners bear no proportion to any of those things which now affect the senses. And although some of those punishments are called by our names, yet their difference is very great. For when you hear of fire, you are taught to understand something else from the expression which follows, that is not quenched, beyond what comes into the idea of other fire.

GREGORY. (Mor. 15. sup. Job 20.) The fire of hell is here wonderfully expressed, for our earthly fire is kept up by heaping wood upon it, and cannot live unless supplied with fuel, but on the contrary the fire of hell, though a bodily fire, and burning bodily the wicked who are put into it, is not kept up by wood, but once made remains unquenchable.
