Someone recently asked me why we keep Shabbat restrictions now if violation of those restrictions was clearly necessary to burn korbanot in the Beit Hamikdash.
My knee-jerk response is: God said so. He said that we have to keep these restrictions, and He said that we have to bring these korbanot, including on Shabbat. This is, of course, the first-order reason why our practices include this apparent contradiction.
However, I think it would be much more edifying - to the asker and also to me, now that my curiosity is piqued - if I could also explain why, to the best of our traditional knowledge, God made the rules that way. (To my surprise, I was unable to find anything directly addressing this point in R' Hirsch's commentary in some parts of the Torah where Shabbat is juxtaposed with the Mishkan and its service, such as Exodus 35:1-2 or Numbers 28:9-10.)
What are traditional conceptual understandings of why we take actions that are normally forbidden on Shabbat in order to bring korbanot?
