Objection 3: Further, one asks for a thing that it may be given to one. Now the chief gift of God is the Holy Ghost, and those gifts that we receive through Him. Therefore the petitions seem to be unfittingly assigned, since they do not correspond to the gifts of the Holy Ghost.
Objection 4: Further, according to Luke, only five petitions are mentioned in the Lord's Prayer, as appears from the eleventh chapter. Therefore it was superfluous for Matthew to mention seven.
Objection 5: Further, it seems useless to seek to win the benevolence of one who forestalls us by his benevolence. Now God forestalls us by His benevolence, since "He first hath loved us" ( 1 Jn. 4:19 ). Therefore it is useless to preface the petitions with the words our "Father Who art in heaven," which seem to indicate a desire to win God's benevolence.
On the contrary, The authority of Christ, who composed this prayer, suffices.
I answer that, The Lord's Prayer is most perfect, because, as Augustine says (ad Probam Ep. cxxx, 12), "if we pray rightly and fittingly, we can say nothing else but what is contained in this prayer of our Lord." For since prayer interprets our desires, as it were, before God, then alone is it right to ask for something in our prayers when it is right that we should desire it. Now in the Lord's Prayer not only do we ask for all that we may rightly desire, but also in the order wherein we ought to desire them, so that this prayer not only teaches us to ask, but also directs all our affections. Thus it is evident that the first thing to be the object of our desire is the end, and afterwards whatever is directed to the end. Now our end is God towards Whom our affections tend in two ways: first, by our willing the glory of God, secondly, by willing to enjoy His glory. The first belongs to the love whereby we love God in Himself, while the second belongs to the love whereby we love ourselves in God. Wherefore the first petition is expressed thus: "Hallowed be Thy name," and the second thus: "Thy kingdom come," by which we ask to come to the glory of His kingdom.
To this same end a thing directs us in two ways: in one way, by its very nature, in another way, accidentally. Of its very nature the good which is useful for an end directs us to that end. Now a thing is useful in two ways to that end which is beatitude: in one way, directly and principally, according to the merit whereby we merit beatitude by obeying God, and in this respect we ask: "Thy will be done on earth as it is in heaven"; in another way instrumentally, and as it were helping us to merit, and in this respect we say: "Give us this day our daily bread," whether we understand this of the sacramental Bread, the daily use of which is profitable to man, and in which all the other sacraments are contained, or of the bread of the body, so that it denotes all sufficiency of food, as Augustine says (ad Probam, Ep. cxxx, 11), since the Eucharist is the chief sacrament, and bread is the chief food: thus in the Gospel of Matthew we read, "supersubstantial," i.e. "principal," as Jerome expounds it.
We are directed to beatitude accidentally by the removal of obstacles. Now there are three obstacles to our attainment of beatitude. First, there is sin, which directly excludes a man from the kingdom, according to 1 Cor. 6:9 , 10 "Neither fornicators, nor idolaters, etc., shall possess the kingdom of God"; and to this refer the words, "Forgive us our trespasses." Secondly, there is temptation which hinders us from keeping God's will, and to this we refer when we say: "And lead us not into temptation," whereby we do not ask not to be tempted, but not to be conquered by temptation, which is to be led into temptation. Thirdly, there is the present penal state which is a kind of obstacle to a sufficiency of life, and to this we refer in the words, "Deliver us from evil."
Reply to Objection 1: As Augustine says (De Serm. Dom. in Monte ii, 5), when we say, "Hallowed be Thy name, we do not mean that God's name is not holy, but we ask that men may treat it as a holy thing," and this pertains to the diffusion of God's glory among men. When we say, "Thy kingdom come, we do not imply that God is not reigning now," but "we excite in ourselves the desire for that kingdom, that it may come to us, and that we may reign therein," as Augustine says (ad Probam, Ep. cxxx, 11). The words, "Thy will be done rightly signify, 'May Thy commandments be obeyed' on earth as in heaven, i.e. by men as well as by angels" (De Serm. Dom. in Monte ii, 6). Hence these three petitions will be perfectly fulfilled in the life to come; while the other four, according to Augustine (Enchiridion cxv), belong to the needs of the present life
Reply to Objection 2: Since prayer is the interpreter of desire, the order of the petitions corresponds with the order, not of execution, but of desire or intention, where the end precedes the things that are directed to the end, and attainment of good precedes removal of evil.
Reply to Objection 3: Augustine (De Serm. Dom. in Monte ii, 11) adapts the seven petitions to the gifts and beatitudes. He says: "If it is fear God whereby blessed are the poor in spirit, let us ask that God's name be hallowed among men with a chaste fear. If it is piety whereby blessed are the meek, let us ask that His kingdom may come, so that we become meek and no longer resist Him. If it is knowledge whereby blessed are they that mourn, let us pray that His will be done, for thus we shall mourn no more. If it is fortitude whereby blessed ere they that hunger, let us pray that our daily bread be given to us. If it is counsel whereby blessed are the merciful, let us forgive the trespasses of others that our own may be forgiven. If it is understanding whereby blessed are the pure in heart, let us pray lest we have a double heart by seeking after worldly things which ere the occasion of our temptations. If it is wisdom whereby blessed are the peacemakers for they shall be called the children of God, let us pray to be delivered from evil: for if we be delivered we shall by that very fact become the free children of God."
Reply to Objection 4: According to Augustine (Enchiridion cxvi), "Luke included not seven but five petitions in the Lord's Prayer, for by omitting it, he shows that the third petition is a kind of repetition of the two that precede, and thus helps us to understand it"; because, to wit, the will of God tends chiefly to this---that we come to the knowledge of His holiness and to reign together with Him. Again the last petition mentioned by Matthew, "Deliver us from evil," is omitted by Luke, so that each one may know himself to be delivered from evil if he be not led into temptation.
Reply to Objection 5: Prayer is offered up to God, not that we may bend Him, but that we may excite in ourselves the confidence to ask: which confidence is excited in us chiefly by the consideration of His charity in our regard, whereby he wills our good---wherefore we say: "Our Father"; and of His excellence, whereby He is able to fulfil it---wherefore we say: "Who art in heaven."
Whether prayer is proper to the rational creature?
Objection 1: It would seem that prayer is not proper to the rational creature. Asking and receiving apparently belong to the same subject. But receiving is becoming also to uncreated Persons, viz. the Son and Holy Ghost. Therefore it is competent to them to pray: for the Son said ( Jn. 14:16 ): "I will ask My [Vulg.: 'the'] Father," and the Apostle says of the Holy Ghost ( Rom. 8:26 ): "The Spirit . . . asketh for us."
Objection 2: Angels are above rational creatures, since they are intellectual substances. Now prayer is becoming to the angels, wherefore we read in the Ps. 96:7 : "Adore Him, all you His angels." Therefore prayer is not proper to the rational creature.
Objection 3: Further, the same subject is fitted to pray as is fitted to call upon God, since this consists chiefly in prayer. But dumb animals are fitted to call upon God, according to Ps. 146:9, "Who giveth to beasts their food and to the young ravens that call upon Him." Therefore prayer is not proper to the rational creatures.
On the contrary, Prayer is an act of reason, as stated above (A[1]). But the rational creature is so called from his reason. Therefore prayer is proper to the rational creature.
I answer that, As stated above (A[1]) prayer is an act of reason, and consists in beseeching a superior; just as command is an act of reason, whereby an inferior is directed to something. Accordingly prayer is properly competent to one to whom it is competent to have reason, and a superior whom he may beseech. Now nothing is above the Divine Persons; and dumb animals are devoid of reason. Therefore prayer is unbecoming both the Divine Persons and dumb animals, and it is proper to the rational creature.
Reply to Objection 1: Receiving belongs to the Divine Persons in respect of their nature, whereas prayer belongs to one who receives through grace. The Son is said to ask or pray in respect of His assumed, i.e. His human, nature and not in respect of His Godhead: and the Holy Ghost is said to ask, because He makes us ask.
Reply to Objection 2: As stated in the FP, Q[79], A[8], intellect and reason are not distinct powers in us: but they differ as the perfect from the imperfect. Hence intellectual creatures which are the angels are distinct from rational creatures, and sometimes are included under them. In this sense prayer is said to be proper to the rational creature.
Reply to Objection 3: The young ravens are said to call upon God, on account of the natural desire whereby all things, each in its own way, desire to attain the Divine goodness. Thus too dumb animals are said to obey God, on account of the natural instinct whereby they are moved by God.
Whether the saints in heaven pray for us?
Objection 1: It would seem that the saints in heaven do not pray for us. A man's action is more meritorious for himself than for others. But the saints in heaven do not merit for themselves, neither do they pray for themselves, since they are already established in the term. Neither therefore do they pray for us.
Objection 2: Further, the saints conform their will to God perfectly, so that they will only what God wills. Now what God wills is always fulfilled. Therefore it would be useless for the saints to pray for us.
Objection 3: Further, just as the saints in heaven are above, so are those in Purgatory, for they can no longer sin. Now those in Purgatory do not pray for us, on the contrary we pray for them. Therefore neither do the saints in heaven pray for us.
