[Avodah] hardest question on SA

[Eli Turkel]

I heard a shiur today where the abbi claimed this was the hardest
question on a psak of the SA

The is a disagreement of Rambam and Rosh about the definition of a
parsha petucha and a parsha stumah.
The psak of the SA is that one should only uses the 1 possibility of a
petucha and the one of the stumah
that is common to both shitot

The question from R Natan Adler (rebbe of CS). Rambam lists all the
parshiot petuchot
and stumot in the Torah based on the Torah of R. Asher. However, given
that sefer Torah one can decide
what is stuma or petucha only using the shitot of Rambam or Rosh.
Hence, what the Rambam call a parsha petucha might according to Rosh
be really a stuma
and now writing it as a petucha according to all shitot doesnt help
since according to Rosh
it is a stumah

Note: mixing up a parsha petucah with a stumah is pasul bideved

Note: We now have keter Aram Tzovah and can see that he used
possibilities for parshiyot
that would indeed be an argument between Rosh and Rambam and so cant
answer that the original
version only used posibilities that was agreed by everyone
