"I was sent only to the lost sheep of the house of Israel." Mt 15:24
Matthew's perspective makes perfect sense in context. It was important that Jesus' disciples remember their audience while not changing Jesus' message. Luke's gospel, because it was addressed primarily to Gentiles, was not concerned with connecting Jesus' teaching to the Torah. Quoting Jesus warning his first followers to avoid Samaria would make no sense to Gentiles who knew nothing about Palestinian geography or the quarrels among Jews.
How important it is to learn to announce the Good News to the people of the 21st century in a form they can understand. For those who have never lived without a computer or a cell phone, images and metaphors that were helpful to the people of the 20th century make little sense. In order to follow the powerful example of the early church, we need to be more sophisticated about social media, the music they enjoy and how they interact with the world.
Today, live the Gospel in a way that speaks to the those born in the 21st century.
