Matthew 13:47

After this, that we may not be confident in the gospel merely preached, nor think that faith only suffices us for salvation, He utters also another, an awful parable. Which then is this? That of the net. "For the kingdom of Heaven is like unto a net, that was cast into the sea, and gathered of every kind; which, when it was full, they drew to shore, and sat down, and gathered the good into vessels, but cast the bad away." And wherein doth 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. Yet surely He saith elsewhere, that the shepherd Himself separates them, but here He saith the angels do this; and so with respect to the tares. How then is it? At one time He discourses to them in a way more suited to their dullness, at another time in a higher strain. And this parable He interprets without so much as being asked, but of His own motion He explained it by one part of it, and increased their awe. For lest, on being told, "They cast the bad away," thou shouldest suppose that ruin to be without danger; by His interpretation He signified the punishment, saying, "They will cast them into the furnace." And He declared the gnashing of teeth, and the anguish, that it is unspeakable. Seest thou how many are the ways of destruction? By the rock, by the thorns, by the wayside, by the tares, by the net. Not without reason therefore did He say, "Broad is the way that leadeth to destruction, and many there be which go away by it."

In fulfilment of that prophecy of Hieremias, who said, I will send unto you many fishers, (Jer. 6:16.) when Peter and Andrew, James and John, heard the words, Follow me, I will make you fishers of men, they put together a net for themselves formed of the Old and New Testaments, and cast it into the sea of this world, and that remains spread until this day, taking up out of the salt and bitter and whirlpools whatever falls into it, that is good men and bad; and this is that He adds, And gathered of every kind.

(Hom. in Ev. xi. 4.) Or otherwise; The Holy Church is likened to a net, because it is given into the hands of fishers, and by it each man is drawn into the heavenly kingdom out of the waves of this present world, that he should not be drowned in the depth of eternal death. This net gathers of every kind of fishes, because the wise and the foolish, the free and the slave, the rich and the poor, the strong and the weak, are called to forgiveness of sin; it is then fully filled when in the end of all things the sum of the human race is completed; as it follows, Which, when it was filled, they drew out, and sitting down on the shore gathered the good into vessels, but the bad they cast away. For as the sea signifies the world, so the sea shore signifies the end of the world; and as the good are gathered into vessels, but the bad cast away, so each man is received into eternal abodes, while the reprobate having lost the light of the inward kingdom are cast forth into outer darkness. But now the net of faith holds good and bad mingled together in one; but the shore shall discover what the net of the Church has brought to land.
