Like the parable of the Tares, earlier in Matthew 13, this parable refers to the final judgment. Here, the imagery is drawn from the separation of edible from inedible fish caught by a net, probably a seine net. One end of the dragnet is held on the shore, the other end is dragged into the sea and returned to the shore. Alternatively, the two ends are held on two boats and then they sweep the sea together. The passage says that "the angels will come and separate the wicked from the righteous" in a similar way to the separation of the tares from the wheat in the parable of the Tares. Arthur Pink explained that "The 'good' fish represent believers; their being 'gathered' speaks of association together—fellowship; while the 'vessels' tell of separation from the world." First, the fishermen will separate believers, and finally angels will take away non-believers to hell. According to J Duncan M Derrett, Professor of Oriental Laws in the University of London, the parable is about the technique of a mission. He explains: Jack Dean Kingsbury, Aubrey Lee Brooks professor of theology at Union Presbyterian Seminary in Richmond, Virginia, asserted that the parable is about the harvest. He explained that the present age is different from the future age, but both stand under the divine ordinance. The church should not attempt to establish a holy community. The association of evil with the righteous is only temporary. In the end, the separation will occur and therefore each Christian must examine himself to avoid being declared evil. John Chrysostom described this as a "terrible parable," noting that:
And wherein does this differ from the parable of the tares? For there too the one are saved, the other perish; but there, for choosing of wicked doctrines; and those before this again, for not giving heed to His sayings, but these for wickedness of life; who are the most wretched of all, having attained to His knowledge, and being caught, but not even so capable of being saved.
Jesus' final comments indicate that "true teachers of the kingdom display the kingdom's treasure for all to see." Reformer John Calvin interpreted the parable to mean:
Christ informs us, that a mixture of the good and the bad must be patiently endured till the end of the world; because, till that time, a true and perfect restoration of the Church will not take place. Again, he warns us, that it is not enough, and—what is more—than it is of little consequence to us, to be gathered into the fold, unless we are his true and chosen sheep... that might communicate to others what they had received. In this way whets and excites their minds more and more to desire instruction. He says that teachers are like householders, who do not only care about their own food, but have a store laid up for the nourishment of others; and who do not live at ease as to the passing day, but make provision for a future and distant period. The meaning, therefore, is, that the teachers of the Church ought to be prepared by long study for giving to the people, as out of a storehouse, a variety of instruction concerning the word of God, as the necessity of the case may require.
William Barclay elaborated that " lays it down that there must be no selectiveness in the preaching of the gospel. To us, that is something of a commonplace... But to the ancient world, this was an amazing thing. The ancient world everywhere was a world of barriers and of contempt." The Parable of the Scribes at the end is generally regarded as part of the parable. But some scholars consider it separate, hence, making up eight—not seven—parables in Matthew 13.
Non-canonical version
The Parable of the Dragnet is also found in the writings of Clement of Alexandria, in the Heliand and the Gospel of Thomas. The storylines are similar but with slight variations. Clement of Alexandria wrote: "The kingdom of heaven is like a man who cast his net into the sea." In the Heliand it is written: "Also its works is like that a man casts a net into the sea, a fishing net into the flood." According to the Gospel of Thomas : "And he said: Man is like a wise fisherman who cast his net into the sea; he drew it up from the sea full of small fish; among them, he found a large good fish, the wise fisherman; he threw all the small fish into the sea, he chose the large fish without difficulty. He who has ears to hear, let him hear!"
