(1) the Church is a separate group of elect composed solely of non-Jews;
(2) Israel is composed only of ethnic Jews and those who have converted under Jewish auspices.
Naturally, Gene is not open to the truth that the Ekklesia is not a separate group of elect but rather refers to Israel. He doesn't want to hear that. He wants non-Jews to stay in church and learn Christian traditions (e.g. pork is tasty on Easter and fondling pigskinned footballs can be a religious experience).
Naturally, Gene disagrees with Paul's assessment in Ephesians 2 that the physical Jews have failed to recognize the covenantal status of non-Jewish Believers. Gene sees such talk as de-legitimizing the Jewish race (which, of course, it does not).
So the lines are becoming sharper with each passing day.
