Stand fast in the Liberty of Jesus Christ and stop submitting to the Judaizers who demand you gain their approval (by not being "racist" and "anti-semitic" and not "homophobic").   The Chosen People are those baptized in Jesus Christ -- we are the heirs of the Promise, the Children of Abraham.   Paul warns of the same "leaven" that Jesus Christ warned against -- the leaven is the doctrines of the Jews.
