Question

Hello Rabbi. I know that in the Rabbi’s view, the inquiry into whether saving a life on the Sabbath is fully permitted or merely overrides the Sabbath has no practical difference. What about “permitted” versus “deferred” in other areas? For example, a positive commandment overriding a prohibition, a brother’s wife in levirate marriage, a unattended corpse that must be buried, and relatives of a priest? And is it possible that this inquiry has significance even without a practical difference? Thank you
