Origen

“ And it is nothing strange if some of the fishes caught are encompassed by the whole texture of the net in the Scriptures, and are pressed in on every side and caught, so that they are unable to escape but are, as it were, absolutely enslaved, and not permitted to escape from the net. And this net has been cast into the sea—the wave—tossed life of men in every part of the world, and which swims in the bitter affairs of life. ”

“ The Divine Scriptures Compared to a Net.
Now, these things being said, we must hold that “the kingdom of heaven is likened to a net that was cast into the sea and gathered of every kind, [1] ” in order to set forth the varied character of the principles of action among men, which are as different as possible from each other, so that the expression “gathered from every kind” embraces both those worthy of praise and those worthy of blame in respect of their proclivities towards the forms of virtues or of vices. ”

“ Only it must be observed, that we are already taught by the parable of the tares and the similitude set forth, that the angels are to be entrusted with the power to distinguish and separate the evil from the righteous; for it is said above, “The Son of man shall send forth His angels, and they shall gather out of His kingdom all things that cause stumbling, and them that do iniquity, and shall cast them into the furnace of fire: there shall be the weeping and gnashing of teeth.” ”
