Memory of the Korban: A Foundational Principle
The Mishna and Gemara guide us with a delicate yet firm hand. We wish to remember the sacrifices, but not to create the illusion that they still exist. This is a fine balance.
We construct a 'zekher' – a symbol, a reminder – but we avoid 'ma'aseh' – a precise imitation that might appear as an actual offering. This is 'memory without enacting'.
אמר רב נחמן: צלי אש אסור לאכול בלילי פסחים, גזירה שמא יאמרו: הרי אנו אוכלין קדשים בחוץ.
Rav Nachman said: It is forbidden to eat roasted meat on Pesach nights, as a decree lest people say: 'Behold, we are eating consecrated offerings outside [the Temple].'
