I am comforted to see that a number of posters have noted that there is a major difference between “yemos hamoshiach” -as per the Rambam paskening like Shmuel in chelek- when nothing changes except “shibud malchyios” (the throwing off of our oppressors yoke).
One question on the Ben Ish Chai- how do we know that the Bnai Yisroel did NOT need another kiddushin after mattan torah?
gavra-a-work- are you referencing a woman ‘married to two men’ as the “mehashtoh’ and ‘leachar zman’ sugya? (Kiddushin, perek Ho-omer) I haven’t looked up your references yet.
I am pretty sure that in that case,she must divorce both.
In any case, this whole thread is totally speculative-as techiyas hameisim is a real difficult concept to understand. Does the person come back as a young man/woman? or as the old man/woman that died?
there may be a small indication from the “atzomos hajeveishim” and the Tanna who declared that he was a descendant of theirs. Presumably, he was not a mamzer-even though he was born later, after their ressuscitation. Was he born to the same parents?
As far as the hetter of a woman “after death”, if my memory serves me correctly, isn’t there a question about “eishes eliyahu”, who went up to heaven alive? was he considered dead to the world?
