Would you mind if I e-mailed you? I married a young man whose mother was reared "Jewish", so technically he is Hebrew by birth. No one in his family practices Judaism per se - some of us are Messianic Jews/Christians, others very interested in roots and just beginning to examine them and their impact. I take that back. His Uncle Jack is now the President of his synagogue and just married a woman who converted to Judaism.
When Derek Prince adopted several Jewish girls just after WW2, he observed that although they were being reared in a Christian household, the older they became, the more Jewish they became. It is in the blood.
