Why did Jesus call the Canaanite woman a 'dog'?

In Matthew 15:22-28, when Jesus referred to the Canaanite woman as a 'dog,' He was not demeaning her but rather using the cultural context to expose and affirm her humility and faith. This derogatory term was commonly used in that era, especially reflecting the Jewish-Gentile dynamic. However, the woman's response, 'truth, Lord, yet the dogs eat of the crumbs which fall from the master's table,' demonstrates her understanding of her need for grace despite her status. This interaction illustrates that faith and humility can transcend cultural and social barriers, affirming the biblical truth that those who recognize their need for mercy are ultimately the ones who receive grace from Jesus. It reaffirms the notion that God's love and salvation are extended to all who express their dependence on Him.
