As we have said above, prayer is an act of the reason by which a person pleads with his superior, just in the same way as a command is an act of the reason by which an inferior is directed to do something. Prayer, then, properly pertains to one who has the use of reason and who also has a superior with whom he can plead. The Persons of the Trinity have no superior; the brute animals have no reason. Hence prayer belongs neither to the Divine Persons nor to the brute creation, but is peculiar to rational creatures. Some, however, argue that prayer cannot be peculiar to rational creatures, thus: 1. To ask and to receive belong to the same person. But the Divine Persons receive: the Son, namely, and the Holy Spirit. Consequently They can also pray; indeed it is the Son Himself Who says, _I will ask the Father_,[189] and the Apostle says of the Holy Spirit, _The Spirit Himself asketh for us_.[190] But it belongs to the Divine Persons to receive by Their nature, whereas to pray belongs to one who receives through grace. The Son is said to ask or pray according to the nature He took upon Himself--that is according to His Human, and not according to His Divine, Nature; the Holy Spirit, too, is said to petition because He makes us petition. 2. But further, the Angels are superior to the rational creation since they are intellectual substances; but it belongs to the Angels to pray, for it is said in the Psalm[191]: _Adore Him, all ye His Angels_. But the intellect and the reason are not different faculties in us, though they do differ in the sense that one is more perfect than the other. Consequently the intellectual creation, such as are the Angels, is sometimes distinguished from the rational creation, but at other times both are embraced under the one term "rational." And it is in this latter sense of the term "rational" that prayer is said to be peculiar to the rational creation. 3. Lastly, he prays who calls upon God; for it is chiefly by prayer that we call upon God. But the brute animals also call upon God, for the Psalmist says: _Who giveth to beasts their food, and to the young ravens that call upon Him._[192] But the young ravens are said to call upon God by reason of those natural desires by which all things, each in their own fashion, desire to obtain the Divine goodness. In the same way brute animals are said to obey God by reason of the natural instinct by which they are moved by God. "Reward them that patiently wait for Thee, that Thy Prophets may be found faithful: and hear the prayers of Thy servants. According to the blessing of Aaron over Thy people, and direct us into the way of justice, and let all know that dwell upon the earth, that Thou art God the beholder of all ages."[193] XI Do the Saints in Heaven Pray for Us? _This is he who prayeth much for the people and for all the holy city, Jeremias the Prophet of God._[194]
