The gemara in Zevachim 47a quotes the opinion of Rabbi Elazar Bar Rabbi Yose who holds that not only the kohen who is being makrev a korban can disqualify, but even the owner can disqualify. Upon this opinion we can come to a case where the Sotah herself will have in mind while the kohen is preparing the mincha for a non accepted time, and will make the korban mincha into piggul. Then the water won't be valid to test the woman since the korban wasnt accepted since it was turned piggul, and no one but her will know that she has no risk even though she is guilty. So how can we confidently say the sotah test always works if there is a loophole for the Sotah to be guilty and survive?
This question was asked by Rav Yosef Engel and he gave 80 answers in his Gevuros Shimonim. I beileve one of his answers is that this shitta of Rabbi Elazar Bar Rabbi Yose only applies by Kodsehi Kalim,but not by Kodesh Kodoshim. Does anyone know his other answers? (I do not own his sefer)
I also wanted to know if one of his answers states that although there is a loophole, we can still say that a miracle will occur and if she is guilty she would still be killed even though the korban mincha was invalid.
