Matthew 13:40

(Quæst. Ev. i. 10.) That the tares are first separated, signifies that by tribulation the wicked shall be separated from the righteous; and this is understood to be performed by good Angels, because the good can discharge duties of punishment with a good spirit, as a judge, or as the Law, but the wicked cannot fulfil offices of mercy.

"And He answered," so it is said, "and said unto them, He that soweth the good seed is the Son of Man; the field is the world, the good seed, these are the children of the kingdom, but the tares are the children of the wicked one; the enemy that soweth them is the devil; and the harvest is the end of the world, and the reapers are angels. As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world. The Son of Man shall send His angels, and they shall gather out of His kingdom all things that offend, and them which do iniquity; and shall cast them into the furnace of fire, there shall be weeping and gnashing of teeth. Then shall the righteous shine forth as the sun in the kingdom of their Father." For whereas He Himself is the sower, and that of His own field, and out of His own kingdom He gathers, it is quite clear that the present world also is His. But mark His unspeakable love to man, and His leaning to bounty, and His disinclination to punishment; in that, when He sows, He sows in His own person, but when He punishes, it is by others, that is, by the angels.

For this is part of the wiles of the Devil, to be ever mixing up truth with error. The harvest is the end of the world. In another place He says, speaking of the Samaritans, Lift up your eyes, and consider the fields that they are already white for the harvest; (John 4:35.) and again, The harvest truly is great, but the labourers are few, (Luke 10:2.) in which words He speaks of the harvest as being already present. How then does He here speak of it as something yet to come? Because He has used the figure of the harvest in two significations as He says there that it is one that soweth, and another that reapeth; but here it is the same who both sows and reaps; indeed there He brings forward the Prophets, not to distinguish them from Himself, but from the Apostles, for Christ Himself by His Prophets sowed among the Jews and Samaritans. The figure of harvest is thus applied to two different things. Speaking of first conviction and turning to the faith, He calls that the harvest, as that in which the whole is accomplished; but when He enquires into the fruits ensuing upon the hearing the word of God, then He calls the end of the world the harvest, as here.

By the harvest is denoted the day of judgment, in which the good are to be separated from the evil; which will be done by the ministry of Angels, as it is said below, that the Son of Man shall come to judgment with His Angels. As then the tares are gathered and burned in the fire, so shall it be in the end of this world. The Son of man shall send forth his Angels, and they shall gather out of his kingdom all offences, and them which do iniquity.
