Now He calls those parties, lovers of a true and indestructible good. They will therefore be filled with that food of which the Lord Himself says, My meat is to do the will of my Father, which is righteousness; and with that water, of which whosoever drinks, as he also says, it shall be in him a well of water, springing up into everlasting life.
To those hungering and thirsting, a full supply, as it were a refreshment to those labouring and bravely contending for salvation: Blessed are they which do hunger and thirst after righteousness, for they shall be filled.
Or He speaks of food with which they shall be filled at this present; to wit, that food of which the Lord spake, “My food is to do the will of my Father, "that is, righteousness, and that water of which whoever drinks it shall be in him “a well of water springing up to life eternal.”
But now, to conclude by summing up this passage, what can be named or thought of more laborious and toilsome, where the believing soul is straining every nerve of its industry, than the subduing of vicious habit? Let such an one cut off the members which obstruct the kingdom of heaven, and not be overwhelmed by the pain: in conjugal fidelity let him bear with everything which, however grievously annoying it may be, is still free from the guilt of unlawful corruption, i.e. of fornication: as, for instance, if any one should have a wife either barren, or misshapen in body, or faulty in her members—either blind, or deaf, or lame, or having any other defect—or worn out by diseases and pains and weaknesses, and whatever else may be thought of exceeding horrible, fornication excepted, let him endure it for the sake of his plighted love and conjugal union; and let him not only not put away such a wife, but even if he have her not, let him not marry one who has been divorced by her husband, th...
Fortitude corresponds to those hungering and thirsting: for they labour in earnestly desiring joy from things that are truly good, and in eagerly seeking to turn away their love from earthly and corporeal things: and of them it is here said, Blessed are they which do hunger and thirst after righteousness.
He taught that we must seek after righteousness with earnest desire, not with fainthearted energy. Indeed, he calls those persons blessed who in their search for righteousness virtually burn with passionate longing in their hunger and thirst. For if each one of us really hungers and thirsts for righteousness with eager desire, we can do nothing else but think and seek after righteousness. It is necessary that we eagerly desire that for which we hunger and thirst. .
Rightly then the One who is the heavenly bread and the fountain of living waters promises in return to those who thus hunger and thirst the fullness of perpetual refreshment: “Blessed are those who hunger and thirst for righteousness, for they shall be satisfied.” This indeed is that righteousness of faith that comes from God and Christ, of which the apostle says, “The righteousness of God through faith in Jesus Christ in all and upon all who believe in him.” .
Hunger and thirst; i.e. spiritually, with an earnest desire of being just and holy. But others again understand such as endure with patience the hardships of hunger and thirst. (Witham)
Rupertus understands those to whom justice is denied, such as poor widows and orphans. Maldonatus those who from poverty really suffer hunger and thirst, because justice is not done them. (Menochius)
They shall be filled with every kind of good in their heavenly country. I shall be filled when thy glory shall appear. (Psalm xvi.)
The blessedness which He appropriates to those who hunger and thirst after righteousness shows that the deep longing of the saints for the doctrine of God shall receive perfect replenishment in heaven; then “they shall be filled.”
It is not enough that we desire righteousness, unless we also suffer hunger forit, by which expression we may understand that we are never righteous enough, but always hunger after works of righteousness.
Note how drastically he expresses it. For Jesus does not say, “Blessed are those who cling to righteousness,” but “Blessed are those who hunger and thirst after righteousness”—not in a superficial way but pursuing it with their entire desire. By contrast, the most characteristic feature of covetousness is a strong desire with which we are not so hungry for food and drink as for more and more things. Jesus urged us to transfer this desire to a new object, freedom from covetousness. The Gospel of Matthew, Homily
What sort of righteousness? He means either the whole of virtue, or that particular virtue which is opposed to covetousness. For since He is about to give commandment concerning mercy, to show how we must show mercy, as, for instance, not of rapine or covetousness, He blesses them that lay hold of righteousness.
And see with what exceeding force He puts it. For He said not, Blessed are they which keep fast by righteousness, but, Blessed are they which do hunger and thirst after righteousness: that not merely anyhow, but with all desire we may pursue it. For since this is the most peculiar property of covetousness, and we are not so enamored of meat and drink, as of gaining, and compassing ourselves with more and more, He bade us to transfer this desire to a new object, freedom from covetousness.
Then He appoints the prize, again from things sensible; saying, for they shall be filled. Thus, because it is thought that the rich are commonly made such by covetousness, Nay, says He, i...
Then he designates the prize, again by analogy with things sensible, saying, “for they shall be filled.” Thus, because it is commonly thought that the rich are made wealthy through their own greed, Jesus says in effect: “No, it is just the opposite. For it is righteousness that produces true wealth. Thus so long as you act righteously, you do not fear poverty or tremble at hunger. Rather those who extort are those who lose all, while one who is in love with righteousness possesses all other goods in safety.” If those who do not covet enjoy such great abundance, how much more will they be ready to offer to others what they have. The Gospel of Matthew, Homily
All good which men do not from love of the good itself is unpleasing before God. He hungers after righteousness who desires to walk according to the righteousness of God; he thirsts after righteousness who desires to get the knowledge thereof.
Such is the bounty of a rewarding God, that His gifts are greater than the desires of the saints.
Or, this is again a promise of a temporal reward; for as covetousness is thought to make many rich, He affirms on the contrary that righteousness rather makes rich, for He who loves righteousness possesses all things in safety.
Since He is about to speak about almsgiving, He first shows that one must pursue righteousness, and not give alms from what has been acquired by theft and extortion. And one must avidly practice righteousness, for this is what it means to "hunger and thirst’’. Since it is the greedy who are thought to be well off and satisfied, Jesus says that it is rather the righteous who shall be filled, even here in this life, for what is theirs they possess with surety.
