In Matthew 15:26 and Mark 7:27 the Lord Jesus referred to Jews as “children” and to the Gentiles as “dogs”. In Romans 10:12, Galatians 3:28 and Colossians 3:11 I read “there is no difference?” What brought about the change?
In Matt. 15:26 the Lord said, “It is not right to take the children’s bread and toss it to their dogs.” His point was that it wasn’t right to take something meant for one group and give it to another group. His comments were not meant to be demeaning to Gentiles. He proved that when He commended the Gentile woman for her faith and delivered her daughter from demon possession.
Paul was showing us that in the Church there is no difference between Jew and Gentile but all are one in Christ. All believers are saved by grace and will go in the rapture and receive their inheritance as part of the Church, whether Jew or Gentile.
