Shmendrick, I do not presume to either agree or disagree with a Gadol. I follow piskei halacha. And I, as most people, have been taught all my life that the religion always follows the mother. If she is a Yid her child is a FULL Yid. Perhaps there is an exception when speaking of someone fathered by one of the nations not allowed to be part of K’hal Yisrael. But I doubt one could easily find an authentic Moabite these days.
I will humbly admit to not understanding all the things you quoted, but I suggest you speak to your Rov and ask point blank if the child of a Jewish woman is Jewish or not.
