Theophylact of Ohrid
Catena Aurea · Markusevangelium 7
And from thence he arose, and went into the borders of Tyre and Sidon, and entered in to an house, and would have no man know it: but he could not be hid. For a certain woman, whose young daughter had an unclean spirit, heard of him, and came and fell at his feet: The woman was a Greek, a Syrophenician by nation; and she besought him that he would cast forth the devil out of her daughter. But Jesus said unto her, Let the children first be filled: for it is not meet to take the children’s bread, and to cast it unto the dogs. And she answered and said unto him, Yes, Lord: yet the dogs under the table eat of the children’s crumbs. And he said unto her, For this saying go thy way; the devil is gone out of thy daughter. And when she was come to her house, she found the devil gone out, and her daughter laid upon the bed.
He calls the Gentiles dogs, as being thought wicked by the Jews; and He means by bread, the benefit which the Lord promised to the children, that is, to the Jews. The sense therefore is, that it is not right for the Gentiles first to be partakers of the benefit, promised principally to the Jews. The reason,therefore, why the Lord does not immediately hear, but delays His grace, is, that He may also shew that the faith of the woman was firm, and that we may learn not at once to grow weary in prayer, but to continue earnest till we obtain.
