Chazal have disputes only on correct viewpoint - all they say is true

From Daas Torah - translation copyrighted

Shomer Emunim Hakadmon (Second Introduction First Principle):… Included in our faith (emuna) is to believe in all the words of the Talmudic Sages – even if some of their words appear unlikely and against the laws of nature. We are to ascribe the problem to our understanding and not them. That is because all their words were said with ruach hakodesh that was within them. Therefore all those who ridicule any aspect of their words is severely punished as we see in Eiruvin (21b), Gittin (57a), “All those who ridicule the words of the Sages are punished in Hell in boiling excrement.” Bava Basra (75a) relates that a certain student ridiculed words of the Sages [and was turned into a heap of bones]. And this prohibition also applies in the case of midrashim where there is a dispute between the Sages. That is because there is nothing in the words of the Sages that is insignificant or meaningless. All that they say is true (eilu v’eilu) and therefore both sides are saying something of value… For example Rav and Shmuel have a dispute in Berachos (61a). One says that Eve was a attached to Adam (like Siamese twins) while the other said she was simply an insignificant appendage like a tail. In fact both views are true from different perspectives as we know from the teachings of the Arizal. This is the way it is for all other matters which two Sages disagree – both sides are true and correct depending on the place and time or world and perspective. You should know that even those matters mentioned in the Talmud which appear to be unnecessary or imprecise – that is simply not true. In fact these matters have esoteric meaning or important allusions…
