Did Jesus call the Caananite woman a dog yes or no?
Did Jesus call the Pharisies children of the devil yes or no?
Because of their behavior.
Nice try though, using God’s word to justify condemning God’s children.
Jesus chose to reveal his identity as the Messiah to that Canaanite “dog” before anyone else, and the Pharisees were the same race that He was. Hyperbole was then, as it is now, a common tool Jews used to express a point and Jesus used it to great effect.
He looks only at the heart. We are the ones who can’t get past the skin.
