A bit late to the thread but if your still interested
Does that make my Grandad Jewish even though he wasn't raised in the Jewish religion and didn't have a Jewish father?Sort of. He would have been "legally jewish" but would needed to have be circumsized/bar mitzvah'd
2. To my understanding Jewishness is passed down through the maternal line so my mother and I are not Jewish but someone referred to us as a "seed of Isreal." Does that mean anything more than we have Jewishness running through the paternal line?
its because of a lack of dna testing back in the day (& rumors of rape against jewish women) so it was easier to prove it on a mothers line rather then the fathers
although later professional dna studys showed that the majority like 90% or something of ashkenazi jews actually all descend from 4 specific women all from eastern europe/married to middle eastern men yeeaars ago due to 'intergration' into their mothers country (& just enough variation for the descendants to meet & marry each other) these children simply survived & bred the foundations of whats now the ashkenazis so one of them will likely also be your/your grandfathers ancestor aswell - which would make sense as europe itself has always been a patriacle society so 4 men 'running' their wives/familys how they were raised while the children being cared for day to day by a 'normal' socially acceptable mother makes more sense then a group of women having survived years of persecution & breeding a continual line
it is controversial though as is the whole 'mothers, mothers, mothers' idea (theyres also a video on youtube where israelis were talked to on the street & most accepted a male father makes a child jewish by personal opinion)
3. I don't understand why Jewish law only permits Jewishness to pass down the maternal line and exclude children born to a Jewish father and non Jewish mother - it seems very odd to exclude certain members of the family?
Because a child that comes out of a jewish woman is garunteed to be biologically related a man's paternity can't be 100% sure unless there was no other men around (affairs/rape/prostitution ect)
4. My elderly cousin said something about how my Great Grandmother could only see her parents when they were asleep because they discommunicated her. Is this some mad orthodox rule or/and what am I not understanding here
She just knew where they lived & could literally see them when they were asleep as they wouldn't see her back via the window theres nothing orthodox about it, just longing to be near them
