The MB forbids asking a gentile to light candles for Neilah. Why is this not categorised as Shvus bemokom Mitzva and / or zorceh rabbim which is permitted (even though the Melocho is min Hatorah)? Thanks very much
See Rema O:CH 276-2 that we may not ask a gentile to do a melacha d’orayso unless it is needed for many people and there is a great need. Then see and M:B 276-24 that even if there is a great need many poskim don’t allow it, and therefore it shouldn’t be done.
