There is neither male nor female in Christ Jesus, and women DID, Biblically, have a legal right to inherit.
28There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus. 29And if you belong to Christ, then you are Abraham’s seed and heirs according to the promise.
This passage shows exactly what we were talking about. In Christ both male and female is entitled to the inheritance of Abraham. If they are the descendant of Sarah the free women or Hagar the Slave women. They both share in the inheritance. As gentiles Paul tells us that we are adopted into the family. I study Kabbalah under Hasidic Rabbi so I have some rights because of that.
