Haydock's Catholic Bible Commentary: Matthew
Ver. 12. Scandalized. When the Pharisees had received our Lord's answer, they had nothing to reply. His disciples perceiving their indignation, came and asked Jesus if he observed they were scandalized, i.e. offended. It is probable the disciples were also a little hurt, or afraid lest his words were contrary to the law of Moses or the tradition of the ancients, and took this occasion of having their scruples removed. St. Hilary, St. Chrysostom and Theophylactus understand this answer, Every plant, &c. to signify that every doctrine not proceeding from God, consequently the traditions of the Pharisees here in question, were to be eradicated by the promulgation of the gospel truths, which were not to remain unpublished on account of the scandal some interested or prejudiced persons might choose to take therefrom. (Jansenius) --- It must be here observed, that Christ was not the direct cause of scandal to the Jews, for such scandal would not be allowable; he only caused it indirectly, because it was his doctrine, at which, through their own perversity, they took scandal. (Denis the Carthusian)
Ver. 14. Let them alone. It must not be hence inferred, that he desired not the conversion of the Scribes and Pharisees. He only says: if, through their own perversity, they choose to take scandal, let them do it; we must not neglect to teach the truth, though it displease men. (St. Jerome) --- When, says St. Gregory, we see scandal arise from our preaching truth, we must rather suffer it to take place than desert the truth. Our Lord says they are blind, let us leave them. For the land which has often been watered with the dews of heaven, and still continues barren is deserted. Behold your house shall be left desolate. (Luke xiii. 35) And Isaias (v. 6.) says, It shall not be pruned, and it shall not be digged, but briers and thorns shall come upon it; and I will command the clouds to rain no more rain upon it. For, although God never refuses man grace sufficient to enable him to rise, if he pleases, yet he sometimes denies such assistance as would render his rise easy. The state of a sinner is then desperate indeed, when Christ tells his disciples to leave him. For as the Sodomites were destroyed, so soon as Lot, who was just and good in the sight of God, had departed from them, and as Jerusalem was laid waste when Jesus went out of it, (for he suffered without the gates) so the sinner is in a very dangerous state, when he is left by the ministers of religion as one infected with a mortal distemper. (Paulus de Palacio)
Ver. 19. For out of the heart. We must here observe, that our divine Redeemer mentions offences against our neighbour, to shew us that he is even more desirous we should love our neighbour than worship himself. (Idem.)
Ver. 21. Confines of Tyre. It perhaps may be asked, why Jesus went among the Gentiles, when he had commanded his apostles to avoid those countries? One reason may be, that our Saviour was not subject to the same rules he gave his disciples; another reason may be brought, that he did not go then to preach; hence St. Matthew observes that he kept himself retired. (St. Chrysostom) --- Tyre and Sidon were both situated on the Mediterranean sea, about 20 miles distant from each other, and the adjoining country to the west and north of Galilee was called the coast or territories of Tyre and Sidon. The old inhabitants of this tract were descendants of Chanaan, (for Sidon was his eldest son) and continued in possession of it much longer than they did of any other part of the country. The Greeks called it Phœnicia; and when, by right of conquest, it became a province of Syria, it took the name of Syrophœnicia; hence the woman, whom St. Matthew calls a Chanaanite, St. Mark calls a Syrophœnician and Gentile; as being both by religion and language a Greek.
Ver. 22. It is probable that woman first cried out before the door, and assembled a crowd, and then went into the house. Have mercy on me. The great faith of the Chanaanæan woman is justly extolled. She believed him to be God, whom she calls her Lord, and him a man, whom she styles the Son of David. She lays no stress upon her own merits, but supplicates for the mercy of God; neither does she say, have mercy on my daughter, but have mercy on me. ... To move him to compassion, she lays all her grief and sorrow before him in these afflicting words: my daughter is grievously afflicted by a devil. (Glossa.)
Ver. 23. He answered her not. It must not be supposed that our Saviour refused to hear the woman through any contempt, but only to shew that his mission was in the first instance to the Jews; or to induce her to ask with greater earnestness, so as to deserve more ample assistance. (Denis the Carthusian)
Ver. 26-27. And to cast it to the dogs; i.e. to Gentiles, sometimes so called by the Jews. (Witham) --- The diminutive word Kunarios, or whelp, is used in both these verses in the Septuagint. Our Lord crosses the wishes of the Chanaanæan, not that he intended to reject her, but that he might bring to light the hidden and secret treasure of her virtue. Let us admire not only the greatness of her faith, but likewise the profoundness of her humility; for when our Saviour called the Jews children, so far from being envious of another's praise, she readily answers, and gives them the title of lords; and when Christ likened her to a dog, she presently acknowledges the meanness of her condition. (St. Chrysostom, hom. liii.) He refused at first to listen to her petition, says the same saint, to instruct us with what faith, humility, and perseverance we ought to pray. To make his servants more sensible of his mercy, and more eager to obtain it, he often appears to pay no attention to their prayers, till he had exercised them in the virtues of humility and patience. Ask, and you shall receive; knock, and it shall be opened to you. (Haydock)
Ver. 28. Be it done. In the beginning God said, Let there be light, and there was light; here Jesus Christ says, let it be done, &c. and her daughter was healed from that hour. So powerful with God is earnest and fervent prayer. (St. Chrysostom, hom. liii.)
