These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:
Matthew 10:5-6
But he answered and said, I am not sent but unto the lost sheep of the house of Israel.
Matthew 15:25
The above verses show that Jesus' message was intended for a select group of people. It was never meant to become a mass inclusive religious movement.
