For sometimes "spirit" refers to man's pride: "Turn away from a man whose breath is in his nostrils, for of what account is he?" (Is 2:22); it is called pride, because as wineskins are inflated with air, so men by pride: "Puffed up by his sensuous mind" (Col 2:18). Therefore, Blessed are the poor , i.e., those who have little of the spirit of pride.
Or "spirit" is taken for man's will. For some are humble of necessity and are not happy, but they pretend humility.
Thirdly, it is taken for the Holy Spirit; hence blessed are the poor in spirit , who are humble through the Holy Spirit. And those two practically turn out to be the same.
He says, poor in spirit , because humility gives the Holy Spirit: "This is the man to whom I will look, he that is humble and contrite in spirit, and trembles at my word" (Is 66:2). To those poor a kingdom is promised, in which is understood supreme excellence. And although it is the reward for every virtue, it is given in a special way to humility; because "everyone who humbles himself shall be exalted" (Mt 23:12); "He who is lowly in spirit will obtain honors" (Pr 29:22). Or another way, according to Jerome: poor in spirit literally, in disowning temporal goods. He says, in spirit , because some are poor by necessity, but happiness is not owed to such but to those who are poor by will.
The poor are described in two ways,
because even though some have riches, they do not have them in their heart: "If riches increase, set not your heart on them" (Ps 62:10).
Some neither have nor desire them, and that is more secure, because the mind is drawn from spiritual things by riches. And these are properly called poor in spirit , because the acts of the gifts, which are above the human way of acting, belong to the happy man. And that a man reject all riches, so that he does not seek them at all is also above the human way of acting. To those is promised the kingdom of heaven, which is marked not only by the loftiness of honor but by abundance of wealth: "Has not God chosen the poor of this world to be rich in faith?" (Jas 2:5).
Note that Moses first promised riches: "The Lord your God will set you high above all the nations of the earth" (Dt 28:1), and in v. 3: "Blessed shall you be in the city and blessed in the field." Therefore, to distinguish the old law from the new, the Lord first places happiness in the contempt for temporal things.
Note also, according to Augustine, that this beatitude pertains to the gift of fear, because fear, particularly filial, makes one have reverence for God and, as a result, a man despises riches.
Note also that Isaiah presents the beatitudes in descending order: "There shall come forth a shoot from the stump of Jesse, and a branch shall grow out of his roots. And the Spirit of the Lord shall rest upon him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and fear of the Lord, and his delight shall be in the fear of the Lord" (Is 11:1). Christ, on the other hand, begins with the gift of fear, namely, from poverty, because Isaiah foretold Christ's coming to earth; but Christ attracted his followers upwards from the earth.
(5) Blessed are the meek . This is the second beatitude. But lest anyone suppose that poverty is sufficient for happiness, he shows that it is not; indeed, meekness, which puts a restraint on anger is required, as temperance does to pleasures. For one is meek who is not irritated. But this could be done by a virtue, so that one does not become angry without just cause; however, even if you have a just cause and are not vexed, it is strictly beyond human power. Therefore he says, Blessed are the meek . For a struggle arises on account of an abundance of external goods; therefore, there would never be conflict, if man were not affected by riches. Hence those who are not meek are not poor in spirit. That is why he says immediately, Blessed are the meek . Note that this consists in two things: first, that a man not become angry; secondly, that if he becomes angry, he tempers the anger.
Thus Ambrose says: "It is the mark of a prudent man to temper movements to anger, nor is it less virtuous to get angry temperately than not to get angry at all. And in general I consider the latter milder, the former stronger."
Chrysostom says: "In the midst of eternal promises he places one which is earthly." Hence according to the letter the meek possess this earth. For many fight to acquire possessions, but frequently they lose life and everything else; whereas the meek often have the whole: "The Meek shall possess the land" (Ps 37:11). but it is better to explain it in reference to the future. Then it is explained in a number of ways.
Hilary, in this way: They shall inherit the earth ,
i.e., the glorified body of Christ, because they will be conformed in their bodies to that brightness. "Your eyes will see the king in his beauty; they will behold a land that stretches far" (Is 33:17); "He will change our lowly body to be like his glorious body" (Phil 3:21).
Or in another way: this is the earth of the dead, because it is subject to corruption; but it will be freed from corruption, according to the Apostle (Rom 8:21). Therefore this earth, when it will be renewed and freed from the slavery of corruption, will be called the earth of the living.
Or by earth is understood the empyrean heaven, in which are the blessed; and it is called earth, because as earth is to heaven, so that heaven to the heaven of the Holy Trinity.
Or they shall merit the earth , i.e., their glorified body.
Augustine explains it metaphorically and says that "by this must be understood a certain stability of the saints in their knowledge of the first truth"; "I believe that I shall see the goodness of the Lord in the land of the living" (Ps 27:13).
(4) The second beatitude is adapted to the gift of piety, because, properly speaking, those not content with the divine order get angry. Blessed are those who mourn . Two beatitudes, through which we are drawn from the evil of covetousness and cruelty, have been presented. Here is presented a third, by which we are drawn from the evil of harmful pleasure, and it is Blessed are those who mourn . In the Old Testament earthly things were promised and earthly happiness: "They shall be radiant over the goodness of the Lord, over the grain, the wine and the oil" (Jer 31:12). But contrariwise the Lord promises happiness in mourning. Yet it should be noted that not just any weeping is mourning, but that by which one weeps over a dead person beloved to him. For the Lord speaks here by hyperbole. As above he said, Blessed are the poor , so here he mentions the bitterest mourning; for as those who mourn the dead receive no consolation, so the Lord wishes our life to be a mourning: "Make mourning as for an only son" (Jer 6:26) This mourning can be expounded in three ways:
first, for sins, not only one's own but those of others; because if we mourn the bodily dead, much more the spiritually:"How long will you grieve over Saul?" (1 Sam 16:1); "O that my head were waters, and my eyes a fountain of tears, that I might weep day and night for the slain of the daughter of my people" (Jer 9:1). This beatitude is fittingly placed after the preceding one, for someone could say that it is enough not to do evil. This is true in the beginning before sin; but after sin has been committed, it is not enough, unless he makes satisfaction.
Secondly, it can be taken for the mourning about sojourning with present misery: "Woe is me, that my sojourning is prolonged" (Ps 120:5). This is watered above and below: "Caleb gave her the upper springs and the lower springs" (Jos 15:19).
Thirdly, according to Augustine, for mourning which men have in regard to the joys of the world, which they abandon by coming to Christ; for some men die to the world and the world dies to them: "By which the world has been crucified to me and I to the world" (Gal 6:14) But as we mourn over the dead, so they mourn; because one cannot escape the fact that in abandoning they feel some pain.
Three consolations correspond to these three kinds of mourning:
because for mourning over sins one is granted forgiveness, as David sought in Ps 51 (v. 12): "Restore to me the joy of my salvation."
