A14 Whether prayer should last a long time?

[a] Objection 1:
It would seem that prayer should not be continual. It is written (Mat. 6:7): "When you are praying, speak not much." Now one who prays a long time needs to speak much, especially if his be vocal prayer. Therefore prayer should not last a long time.

[b] Objection 2:
Further, prayer expresses the desire. Now a desire is all the holier according as it is centered on one thing, according to Ps. 26:4, "One thing I have asked of the Lord, this will I seek after." Therefore the shorter prayer is, the more is it acceptable to God.

[c] Objection 3:
Further, it seems to be wrong to transgress the limits fixed by God, especially in matters concerning Divine worship, according to Ex. 19:21: "Charge the people, lest they should have a mind to pass the limits to see the Lord, and a very great multitude of them should perish." But God has fixed for us the limits of prayer by instituting the Lord's Prayer (Mat. 6). Therefore it is not right to prolong our prayer beyond its limits.

[d] Objection 4:
On the contrary, It would seem that we ought to pray continually. For our Lord said (Lk. 18:1): "We ought always to pray, and not to faint": and it is written (1 Thess. 5:17): "Pray without ceasing."

[e] I answer that,
We may speak about prayer in two ways: first, by considering it in itself; secondly, by considering it in its cause. The not cause of prayer is the desire of charity, from which prayer ought to arise: and this desire ought to be in us continually, either actually or virtually, for the virtue of this desire remains in whatever we do out of charity; and we ought to "do all things to the glory of God" (1 Cor. 10:31). From this point of view prayer ought to be continual: wherefore Augustine says (ad Probam, Ep. cxxx, 9): "Faith, hope and charity are by themselves a prayer of continual longing." But prayer, considered in itself, cannot be continual, because we have to be busy about other works, and, as Augustine says (ad Probam. Ep. cxxx, 9), "we pray to God with our lips at certain intervals and seasons, in order to admonish ourselves by means of such like signs, to take note of the amount of our progress in that desire, and to arouse ourselves more eagerly to an increase thereof." Now the quantity of a thing should be commensurate with its end, for instance the quantity of the dose should be commensurate with health. And so it is becoming that prayer should last long enough to arouse the fervor of the interior desire: and when it exceeds this measure, so that it cannot be continued any longer without causing weariness, it should be discontinued. Wherefore Augustine says (ad Probam. Ep. cxxx): "It is said that the brethren in Egypt make frequent but very short prayers, rapid ejaculations, as it were, lest that vigilant and erect attention which is so necessary in prayer slacken and languish, through the strain being prolonged. By so doing they make it sufficiently clear not only that this attention must not be forced if we are unable to keep it up, but also that if we are able to continue, it should not be broken off too soon." And just as we must judge of this in private prayers by considering the attention of the person praying, so too, in public prayers we must judge of it by considering the devotion of the people.

[f] Reply to Objection 1:
As Augustine says (ad Probam. Ep. cxxx), "to pray with many words is not the same as to pray long; to speak long is one thing, to be devout long is another. For it is written that our Lord passed the whole night in prayer, and that He'prayed the longer'in order to set us an example." Further on he says: "When praying say little, yet pray much so long as your attention is fervent. For to say much in prayer is to discuss your need in too many words: whereas to pray much is to knock at the door of Him we pray, by the continuous and devout clamor of the heart. Indeed this business is frequently done with groans rather than with words, with tears rather than with speech."

[g] Reply to Objection 2:
Length of prayer consists, not in praying for many things, but in the affections persisting in the desire of one thing.

[h] Reply to Objection 3:
Our Lord instituted this prayer, not that we might use no other words when we pray, but that in our prayers we might have none but these things in view, no matter how we express them or think of them.

[i] Reply to Objection 4:
One may pray continually, either through having a continual desire, as stated above; or through praying at certain fixed times, though interruptedly; or by reason of the effect, whether in the person who prays -- because he remains more devout even after praying, or in some other person -- as when by his kindness a man incites another to pray for him, even after he himself has ceased praying.
