To the postponement of the heavenly fatherland and the continued dwelling with present misery corresponds the consolation of eternal life: "I will turn their mourning into joy, I will comfort them and give them gladness for sorrow" (Jer 31:13); "You shall be comforted in Jerusalem" (Is 66:13).
Thirdly, to mourning corresponds the consolation of divine love; for when one weeps over the loss of a treasured object, he is consoled, if he acquires something more valuable.
Hence men are consoled, when in place of temporal they receive spiritual and eternal things, which is to receive the Holy Spirit; hence he is called Paraclete (Jn 15:26). For in virtue of the Holy Spirit, who is divine love, men rejoice: "Your sorrow will be turned into joy" (Jn 16:20)
It should be noted that this beatitude is associated with the gift of knowledge, because those mourn who know others' misery; hence Wisdom (14:22) says of some who do not have such knowledge: "They live in great strife due to ignorance, and they call such great evils peace"; and on the other hand: "He who increases knowledge increases sorrow" (Ec 1:18).
It should also be noted that those rewards are so arranged that the subsequent always adds to the preceding. For, first, he said, Blessed are the poor in spirit, for theirs is the kingdom of heaven ; then, because they shall inherit the earth . For it is better to possess than merely to have. Then, after these, they shall be comforted ; for it is more to be comforted than to possess, because some possess things but are not delighted with them.
(6) Then, having given the beatitudes which pertain to removing evil, he now gives one which pertains to producing good. But our good is twofold, namely, of justice and of mercy. In regard to the first he says, Blessed are they who hunger and thirst after righteousness [justice] . Justice is taken in three ways according to Chrysostom and the Philosopher: sometimes for every virtue, which is called legal justice, which commands acts of the virtues. Hence, to the extent that a man obeys the law, he fulfills every virtue. In another way, in as much as it is a special virtue listed among the cardinal virtues and opposed to greed or injustice, and deals with buying and selling and hiring. Therefore, you thirst after justice can be understood in a general sense and in a specific sense.
If it is understood in a general sense, he says this for two reasons.
The first is Jerome's, who says that it is not enough that a man perform a work of justice, unless he acts with desire: "With free will I will sacrifice to you" (Ps 54:6); "My soul thirsts for God, for the living God" (Ps 42:2); "I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the Lord" (Am 8:11). Therefore, it is thirst, when one acts with desire.
Another reason: Justice is twofold, perfect and imperfect. We cannot have the perfect in this world, because "if we say we have no sin, we deceive ourselves, and the truth is not in us" (1 Jn 1:8); "All our righteous deeds are like a polluted garment" (Is 64:6). But we have it in heaven: "Your people shall all be righteous; they shall possess the land forever" (Is 60:21). But we can have the desire for justice here; hence, he says, Blessed are they who hunger and thirst for justice . This is similar to what Pythagoras did. For in his time those who studied were called wise; but Pythagoras did not wish to be called wise, but a philosopher, i.e., a lover of wisdom. In like manner the Lord wishes that his people be and be called lovers of justice.
But if it be understood of specific justice, it consists in a man's rendering to each what is his due. Then it is fitting to state that blessed are they... , because hunger and thirst, properly speaking, pertain to the greedy. For those who desire to possess what belongs to others are never satiated; hence, that hunger about which the Lord speaks is opposed to that of the greedy. And the Lord wishes that we so yearn for that justice, that we are never, as it were, satiated in this life, as the greedy person is never satiated.
For they shall be satisfied . A fitting reward is mentioned, they shall be satisfied :
first, in the eternal vision, for they shall see God in his essence: "I shall be satisfied when your glory shall appear" (Ps 17:15). For nothing will remain to be desired there: "He who pursues righteousness and kindness will find life" (Pr 21:21).
Secondly, in the present, and this is twofold:
one is in spiritual goods, i.e., in fulfilling the commandments: "My food is to do the will of him who sent me, and to accomplish his work" (Jn 4:34).
In another way, it is taken for a fullness of temporal things. Unjust men are never satisfied, but men who have justice itself as their goal can go no further: "The just man eats and satisfies his soul" (Pr 13:25).
This beatitude, according to Augustine, is reduced to the gift of courage, namely, because it belongs to courage that a man act justly. Furthermore, the Lord adds something to the previous reward, because to be satisfied is to have one's desire totally fulfilled.
Note also that first he says Blessed are those who mourn , for when a man is infirm, he does not desire to eat; but he begins to desire when he begins to get well. So it is in matters of the spirit: when men are in sin, they do not feel spiritual hunger; but when their sins are forgiven, they experience that hunger. Therefore he continues at once: Blessed are the merciful , because justice without mercy is cruelty, while mercy without justice is the mother of destruction. Therefore, it is necessary for the two to be joined, as it says in Proverbs (3:3): "Let not mercy and truth forsake you"; "Mercy and truth will meet" (Ps 85:10).
(7) Blessed are the merciful, for they shall obtain mercy . To be merciful is to have a compassionate heart for the wretchedness of others; but we have mercy toward the wretchedness of others, when we regard it as our own. But we grieve over our own wretchedness and strive to remove it. Therefore, you are truly merciful, when you work to relieve the wretchedness others; but we have mercy toward the wretchedness of others, when we regard it as our own. But we grieve over our own wretchedness and strive to remove it. Therefore, you are truly merciful, when you work to relieve the wretchedness of others. Now the wretchedness of our neighbor is twofold:
the first is in temporal matters, and in regard to that wretchedness we should have a compassionate heart: "If anyone has the world's goods and sees his brother in need, yet closes his heart against him, how does God's love abide in him?" (1 Jn 3:17).
The second is that whereby man is made wretched through sin; because just as happiness lies in the works of the virtues, so one's wretchedness lies in vices: "Sin makes a people wretched" (Pr 14:34). Therefore, when we admonish the fallen to return, we are merciful: "Seeing the crowds he had compassion on them" (Mt 9:36). Therefore, the merciful are blessed. And why? Because they shall obtain mercy .
Here it should be noted that God's gifts always outweigh our merits: "The Lord is the one who repays, and he will repay you sevenfold" (Sir 35:13). Consequently, the mercy God bestows on us is much greater than that we bestow on others. That mercy begins in this life in two ways:
first, because our sins are forgiven: "Who forgives all your iniquity" (Ps 103:3).
Secondly, because he removes temporal imperfections, so that he makes his sun to rise. This will be perfected in the future, when all wretchedness, both of guilt and punishment, will be removed: "Your mercy, O Lord, is in heaven" (Ps 36:6). And this is because they shall obtain mercy .
This beatitude is reduced to the gift of counsel, because this is unique counsel, that amid the dangers of this world we should obtain mercy: "Godliness is of value in every way" (1 Tim 4:8); "Let my counsel be acceptable to the king" (Dan 4:27).
(8) Thus have been presented the acts of virtues by which we are removed from evil and do good. Now are presented the acts by which we are disposed for the best; hence Blessed are the pure in heart . This beatitude consists in two things: in the vision of God and the love of neighbor. Hence, he first presents the beatitude pertaining to the vision of God; secondly, to the love of neighbor (v. 9). Therefore Blessed are the pure in heart, for they shall see God .
