John Chrysostom — as excerpted in the Catena Aurea on Matthew 15:21-28

“Observe this woman’s prudence; she does not dare to contradict Him, nor is she vexed with the commendation of the Jews, and the evil word applied to herself; But she said, Yea, Lord, yet the dogs eat of the crumbs which fall from their masters’ table. He said, It is not good; she answers, ‘Yet even so, Lord;’ He calls the Jews children, she calls them masters; He called her a dog, she accepts the office of a dog; as if she had said, I cannot leave the table of my Lord.”
