Yet although the greater Saints are more acceptable to God than are the lesser ones, it is still useful to pray sometimes to the lesser Saints. And this for five reasons: Firstly, because a man sometimes has a greater devotion to some lesser Saint than to one who is greater; and the efficacy of our prayers depends very much on our devotion. Secondly, in order to avoid weariness; for unremitting application to one thing begets distaste; but when we pray to various Saints fresh devotional fervour is stirred up in practically each case. Thirdly, because certain Saints are appointed the patrons of certain particular cases, so S. Antony for the avoidance of hell-fire. Fourthly, that so we may show due honour to them all. Fifthly, because sometimes a favour may be gained at the prayer of many which would not be gained at the prayer of one alone. 3. Christ, even as man, is termed _the Saint of Saints_;[281] and it belongs to Him, as man, to pray. Yet we never ask Christ to pray for us. Hence it is superfluous to make the Saints our intercessors with God. But prayer is an act. And acts belong to individual beings. Consequently, if we were to say, _Christ, pray for us_, we should appear, unless we added something, to be referring this to Christ's Person, and thus we might seem to fall into the error of Nestorius who regarded the Person of the Son of Man as distinct in Christ from the Person of the Son of God; or perhaps, too, into the error of Arius who regarded the Person of the Son as less than the Father. In order, then, to avoid these errors, the Church does not say, _Christ, pray for us_, but _Christ, hear us_, or _Christ, have mercy on us_. 4. Once more, when one is asked to intercede for another, he presents the latter's prayers to him with whom he has to intercede. But it is superfluous to present anything to Him to Whom all things are present. Hence it is superfluous to make the Saints our intercessors with God. But the Saints are not said to present our prayers to God as though they were manifesting to Him something which He did not know, but in the sense that they ask that these prayers may be heard by God, or that they consult the Divine Truth concerning them, so as to know what, according to His providence, ought to be done. 5. Lastly, that must be held superfluous which is done for the sake of something which, whether the former were done or not, would yet take place--or not take place--all the same. But similarly, the Saints would pray for us or not pray for us whether we asked them to do so or not. For if we deserve that they should pray for us, they would pray for us, even though we did not ask them to do so; if, on the other hand, we are not deserving that they should pray for us, then they do not pray for us--even though we ask them to do so. Hence to ask them to pray for us seems altogether superfluous.
