Haydock's Catholic Bible Commentary: Matthew
Chapter 6
Ver. 1. Your justice;[1] in the common Greek copies, your alms, which seems to be the sense in this place. (Witham) --- Hereby it is plain that good works are justice, and that man doing them doth justice, and is thereby just and justified, and not by faith only. All which justice of a christian man, our Saviour here compriseth in the three eminent good works, alms deeds, prayer, and fasting. (St. Augustine, lib. perf. just. chap. viii.) So that to give alms is to do justice, and the works of mercy are justice. (St. Augustine, in Psalm xlix, ver. 5.) (Bristow) --- St. Gregory says, that the man who by his virtuous actions would gain the applause of men, quits at an easy rate a treasure of immense value; for, with what he might purchase the kingdom of heaven, he only seeks to acquire the transitory applause of mortals. This precept of Christ, says St. Chrysostom, beautifully evinces the solicitude and unspeakable goodness of God, lest we should have the labour of performing good works, and on account of evil motives be deprived of our reward. (Hom. xix.) "Shut up alms in the heart of the poor." (Ecclesiasticus xxix. 15.)
Ver. 2. This must be understood figuratively, that we must avoid all ostentation in the performance of our good works. Many respectable authors are of opinion, that it was customary with the Pharisees and other hypocrites, to assemble the poor they designed to relieve by sound of trumpet. (Menochius) --- Let us avoid vain glory, the agreeable plunderer of our good works, the pleasant enemy of our souls, which presents its poison to us under the appearance of honey. (St. Basil)
Ver. 3. Be content to have God for witness to your good works, who alone has power to reward you for them. They will be disclosed soon enough to man, when at the day of general retribution the good and the evil will be brought to light, and every one shall be rewarded according to his works. (Haydock)
Ver. 4. This repaying or rewarding of good works, so often mentioned here by Jesus Christ, clearly evinces that good works are meritorious, and that we may do them with a view to a reward, as David did, propter retributionem. (Haydock)
Ver. 5. Hypocrisy is forbidden in all these three good works of justice, but not the doing of them openly for the glory of God, the edification of our neighbour, and our own salvation. Let your light so shine before men, i.e. let your work be so done in public, that the intention remain in secret. (St. Gregory)
Ver. 6. Because he who should pray in his chamber, and at the same time desire it to be known by men, that he might thence receive vain glory, might truly be said to pray in the street, and sound a trumpet before him: whilst he, who though he pray in public, seeks not thence any vain glory, acts the same as if he prayed in his chamber. (Menochius) --- Jesus Christ went up to the temple, to attend public worship on the festival days.
Ver. 7. [Speak not much.[2] ] Long prayer is not here forbidden; for Christ himself spent whole nights in prayer: and he sayeth, we must pray always; and the apostle, that we must pray without intermission, 1 Thessalonians v.; and the holy Church hath had from the beginning her canonical hours for prayer, but rhetorical and elaborate prayer, as if we thought to persuade God by our eloquence, is forbidden; the collects of the Church are most brief and most effectual. (St. Augustine, ep. 121. chap. viii, ix, x.) (Bristow) --- Perseverance in prayer is recommended us by the example of the poor widow, who by her importunity prevailed over the unjust judge. (St. Chrysostom, hom. xix.) --- The Greek word means, to babble or trifle.
Ver. 9. As God is the common Father of all, we pray for all. Let none fear on account of their lowly station here, for all are comprised in the same heavenly nobility. ... By saying, "who art in heaven," he does not mean to insinuate that he is there only, but he wishes to withdraw the humble petitioner from earth, and fix his attention on heaven. (St. Chrysostom, hom. xx.) Other prayers are not forbidden. Jesus Christ prayed in different words (John, chap. viii.[xvii.?]), and the apostles; (Acts i, 24,) but this is an example of the simple style to be used in prayer, and is applicable to all occasions. --- Hallowed be thy name, from the word holy, be held and kept holy, be glorified by us, and that not only by our words, but principally by the lives we lead. The honour and glory of God should be the principal subject of our prayers, and the ultimate end of our every action; every other thing must be subordinate to this. (Haydock)
Ver. 10. Those who desire to arrive at the kingdom of heaven, must endeavour so to order their life and conversation, as if they were already conversing in heaven. This petition is also to be understood for the accomplishment of the divine will in every part of the world, for the extirpation of error, and explosion of vice, that truth and virtue may everywhere obtain, and heaven and earth differ no more in honouring the supreme majesty of God. (St. Chrysostom, hom. xx.)
Ver. 11. Our supersubstantial bread.[3] So it is at present in the Latin text: yet the same Greek word in St. Luke, is translated daily bread, as we say it in our Lord's prayer, and as it was used to be said in the second or third age, as we find by Tertullian and St. Cyprian. Perhaps the Latin word, supersubstantialis, may bear the same sense as daily bread, or bread that we daily stand in need of; for it need not be taken for supernatural bread, but for bread which is daily added, to maintain and support the substance of our bodies. (Witham) --- In St. Luke the same word is rendered daily bread. It is understood of the bread of life, which we receive in the blessed sacrament. (Challoner) --- It is also understood of the supernatural support of the grace of God, and especially of the bread of life received in the blessed eucharist. (Haydock) --- As we are only to pray for our daily bread, we are not to be over solicitous for the morrow, nor for the things of this earth, but being satisfied with what is necessary, turn all our thoughts to the joys of heaven. (St. Chrysostom, hom. xx.)
Ver. 12. Of all the petitions this alone is repeated twice. God puts our judgment in our own hands, that none might complain, being the author of his own sentence. He could have forgiven us our sins without this condition, but he consulted our good, in affording us opportunities of practising daily the virtues of piety and mildness. (St. Chrysostom, hom. xx.) --- These debts signify not only mortal but venial sins, as St. Augustine often teaches. Therefore every man, be he ever so just, yet because he cannot live without venial sin, ought to say this prayer. (Cont. 2 epis. Pelag. lib. i. chap. 14.) --- (lib. xxi. de civit. Dei. chap. xxvii.) (Bristow)
