<div dir="ltr">RMB: Usually eilu va'eilu isn't about a question of truth, but of law.<br><br>And what we are discussing here is the trickiest case - a machloket about the halachot of what is considered kefirah. The boundaries of what is acceptable (even if incorrect) belief, vs. what is heresy are not unanimously agreed upon. So does elu v'elu break down in this area of halacha? ANY machloket about what is or isn't kefirah raises this question.<br>
<br>Even in straight halacha - does elu v'elu (in the sense that both are true on a deeper level, but only one can actually be accepted as practice) apply to every single machloket? Up to what point? The gemara? The rishonim? Nowadays? Or are there some opinions that are just not true at all? The posek made a mistake - and perhaps eventually realizes this himself and retracts his opinion. Would we say elu v'elu before the retraction, but not after? Or would we say that this is beyond the bounds of elu v'elu?<br>
