[II-II.q.91.a.1.arg.1] It would seem that God should not be praised with the lips. The Philosopher says (Ethic. 1,12): "The best of men ere accorded not praise, but something greater." But God transcends the very best of all things. Therefore God ought to be given, not praise, but something greater than praise: wherefore He is said (Sirach 43:33) to be "above all praise."

[II-II.q.91.a.1.arg.2] Further, divine praise is part of divine worship, for it is an act of religion. Now God is worshiped with the mind rather than with the lips: wherefore our Lord quoted against certain ones the words of Isaiah 29:13, "This people . . . honors [Vulgate: 'glorifies'] Me with their lips, but their heart is far from Me." Therefore the praise of God lies in the heart rather than on the lips.

[II-II.q.91.a.1.arg.3] Further, men are praised with the lips that they may be encouraged to do better: since just as being praised makes the wicked proud, so does it incite the good to better things. Wherefore it is written (Proverbs 27:21): "As silver is tried in the fining-pot . . . so a man is tried by the mouth of him that praiseth." But God is not incited to better things by man's words, both because He is unchangeable, and because He is supremely good, and it is not possible for Him to grow better. Therefore God should not be praised with the lips.

[II-II.q.91.a.1.sc] It is written (Psalm 62:6): "My mouth shall praise Thee with joyful lips."

[II-II.q.91.a.1.co] We use words, in speaking to God, for one reason, and in speaking to man, for another reason. For when speaking to man we use words in order to tell him our thoughts which are unknown to him. Wherefore we praise a man with our lips, in order that he or others may learn that we have a good opinion of him: so that in consequence we may incite him to yet better things; and that we may induce others, who hear him praised, to think well of him, to reverence him, and to imitate him. On the other hand we employ words, in speaking to God, not indeed to make known our thoughts to Him Who is the searcher of hearts, but that we may bring ourselves and our hearers to reverence Him.

Consequently we need to praise God with our lips, not indeed for His sake, but for our own sake; since by praising Him our devotion is aroused towards Him, according to Psalm 49:23: "The sacrifice of praise shall glorify Me, and there is the way by which I will show him the salvation of God." And forasmuch as man, by praising God, ascends in his affections to God, by so much is he withdrawn from things opposed to God, according to Isaiah 48:9, "For My praise I will bridle thee lest thou shouldst perish." The praise of the lips is also profitable to others by inciting their affections towards God, wherefore it is written (Psalm 33:2): "His praise shall always be in my mouth," and farther on: "Let the meek hear and rejoice. O magnify the Lord with me."

[II-II.q.91.a.1.ad.1] We may speak of God in two ways. First, with regard to His essence; and thus, since He is incomprehensible and ineffable, He is above all praise. On this respect we owe Him reverence and the honor of latria; wherefore Psalm 64:2 is rendered by Jerome in his Psalter [Translated from the Hebrew]: "Praise to Thee is speechless, O God," as regards the first, and as to the second, "A vow shall be paid to Thee." Secondly, we may speak of God as to His effects which are ordained for our good. On this respect we owe Him praise; wherefore it is written (Isaiah 63:7): "I will remember the tender mercies of the Lord, the praise of the Lord for all the things that the Lord hath bestowed upon us." Again, Dionysius says (Div. Nom. 1): "Thou wilt find that all the sacred hymns," i.e. divine praises "of the sacred writers, are directed respectively to the Blessed Processions of the Thearchy," i.e. of the Godhead, "showing forth and praising the names of God."

[II-II.q.91.a.1.ad.2] It profits one nothing to praise with the lips if one praise not with the heart. For the heart speaks God's praises when it fervently recalls "the glorious things of His works" [Cf. Sirach 17:7-8. Yet the outward praise of the lips avails to arouse the inward fervor of those who praise, and to incite others to praise God, as stated above.

[II-II.q.91.a.1.ad.3] We praise God, not for His benefit, but for ours as stated.

[II-II.q.91.a.2.arg.1] It would seem that God should not be praised with song. For the Apostle says (Colossians 3:16): "Teaching and admonishing one another in psalms, hymns and spiritual canticles." Now we should employ nothing in the divine worship, save what is delivered to us on the authority of Scripture. Therefore it would seem that, in praising God, we should employ, not corporal but spiritual canticles.

[II-II.q.91.a.2.arg.2] Further, Jerome in his commentary on Ephesians 5:19, "Singing and making melody in your hearts to the Lord," says: "Listen, young men whose duty it is to recite the office in church: God is to be sung not with the voice but with the heart. Nor should you, like play-actors, ease your throat and jaws with medicaments, and make the church resound with theatrical measures and airs." Therefore God should not be praised with song.

[II-II.q.91.a.2.arg.3] Further, the praise of God is competent to little and great, according to Apocalypse 14, "Give praise to our God, all ye His servants; and you that fear Him, little and great." But the great, who are in the church, ought not to sing: for Gregory says (Regist. iv, ep. 44): "I hereby ordain that in this See the ministers of the sacred altar must not sing" (Cf. Decret., dist. xcii., cap. On sancta Romana Ecclesia). Therefore singing is unsuitable to the divine praises.

[II-II.q.91.a.2.arg.4] Further, in the Old Law God was praised with musical instruments and human song, according to Psalm 32:2-3: "Give praise to the Lord on the harp, sing to Him with the psaltery, the instrument of ten strings. Sing to Him a new canticle." But the Church does not make use of musical instruments such as harps and psalteries, in the divine praises, for fear of seeming to imitate the Jews. Therefore in like manner neither should song be used in the divine praises.

[II-II.q.91.a.2.arg.5] Further, the praise of the heart is more important than the praise of the lips. But the praise of the heart is hindered by singing, both because the attention of the singers is distracted from the consideration of what they are singing, so long as they give all their attention to the chant, and because others are less able to understand the thing that are sung than if they were recited without chant. Therefore chants should not be employed in the divine praises.

[II-II.q.91.a.2.sc] Blessed Ambrose established singing in the Church of Milan, a Augustine relates (Confess. ix).

[II-II.q.91.a.2.co] As stated above (Article 1), the praise of the voice is necessary in order to arouse man's devotion towards God. Wherefore whatever is useful in conducing to this result is becomingly adopted in the divine praises. Now it is evident that the human soul is moved in various ways according to various melodies of sound, as the Philosopher state (Polit. viii, 5), and also Boethius (De Musica, prologue). Hence the use of music in the divine praises is a salutary institution, that the souls of the faint-hearted may be the more incited to devotion. Wherefore Augustine say (Confess. x, 33): "I am inclined to approve of the usage of singing in the church, that so by the delight of the ears the faint-hearted may rise to the feeling of devotion": and he says of himself (Confess. ix, 6): "I wept in Thy hymns and canticles, touched to the quick by the voices of Thy sweet-attuned Church."

[II-II.q.91.a.2.ad.1] The name of spiritual canticle may be given not only to those that are sung inwardly in spirit, but also to those that are sung outwardly with the lips, inasmuch as such like canticles arouse spiritual devotion.

[II-II.q.91.a.2.ad.2] Jerome does not absolutely condemn singing, but reproves those who sing theatrically in church not in order to arouse devotion, but in order to show off, or to provoke pleasure. Hence Augustine says (Confess. x, 33): "When it befalls me to be more moved by the voice than by the words sung, I confess to have sinned penally, and then had rather not hear the singer."

[II-II.q.91.a.2.ad.3] To arouse men to devotion by teaching and preaching is a more excellent way than by singing. Wherefore deacons and prelates, whom it becomes to incite men's minds towards God by means of preaching and teaching, ought not to be instant in singing, lest thereby they be withdrawn from greater things. Hence Gregory says (Regist. iv, ep. 44): "It is a most discreditable custom for those who have been raised to the diaconate to serve as choristers, for it behooves them to give their whole time to the duty of preaching and to taking charge of the alms."

[II-II.q.91.a.2.ad.4] As the Philosopher says (Polit. viii, 6), "Teaching should not be accompanied with a flute or any artificial instrument such as the harp or anything else of this kind: but only with such things as make good hearers." For such like musical instruments move the soul to pleasure rather than create a good disposition within it. On the Old Testament instruments of this description were employed, both because the people were more coarse and carnal--so that they needed to be aroused by such instruments as also by earthly promises--and because these material instruments were figures of something else.

[II-II.q.91.a.2.ad.5] The soul is distracted from that which is sung by a chant that is employed for the purpose of giving pleasure. But if the singer chant for the sake of devotion, he pays more attention to what he says, both because he lingers more thereon, and because, as Augustine remarks (Confess. x, 33), "each affection of our spirit, according to its variety, has its own appropriate measure in the voice, and singing, by some hidden correspondence wherewith it is stirred." The same applies to the hearers, for even if some of them understand not what is sung, yet they understand why it is sung, namely, for God's glory: and this is enough to arouse their devotion.
