Precisely; think of how the Jews viewed the Samaritans in terms of how Christians commonly view Moslems. Yet the question I posed is whether the Jewish people are at the very least, the least of Jesus' brethren, not are they the only brethren of the Messiah.
OK—then I’ll answer the question as I see it—there are no “least” of Jesus’ brethren. There are no “greatest.”
