Bede the Venerable — as excerpted in the Catena Aurea on Mark 7:24-30

“(ubi sup.) The time will come when even you who are Gentiles will obtain salvation; but it is right that first the Jews who deservedly are wont to be called by the name of children of God’s ancient election, should be refreshed with heavenly bread, and that so at length, the food of life should be ministered to the Gentiles. There follows: For it is not meet to take the children’s bread, and to cast it to the dogs.”
