Fratelli Tutti §80

⁸⁰ Jesus told the parable of the Good Samaritan in answer to the question: Who is my neighbour? The word “neighbour”, in the society of Jesus’ time, usually meant those nearest us. It was felt that help should be given primarily to those of one’s own group and race. For some Jews of that time, Samaritans were looked down upon, considered impure. They were not among those to be helped. Jesus, himself a Jew, completely transforms this approach. He asks us not to decide who is close enough to be our neighbour, but rather that we ourselves become neighbours to all.
