At this stage of the Seder, we combine the Maror with the Matzah according to the opinion of Hillel. Most haggadahs state at this point: “This is in remembrance of the Temple, as Hillel used to do.” Hillel was of the opinion that in order to fulfill the mitzvos of eating maror and matza (and the passover offering during the time that the Temple stood), they must be eaten together.
The halacha is not like Hillel and we only eat Korech as a rememberance of the Temple. The interesting thing is that while we do find in halacha that we will fulfill a minority opinion if possible but here the minority opinion is incorporated as an actual step of the seder. Why is it that Hillel’s opinion merited to be added as a separate step of the seder and why was it specifically added as a “rememberance of the Temple”?
Hillel was the paradigm of patience and truly embodied the concept of “loving your fellow Jew”. It is Hillel’s example that we must follow in order to merit the construction of the Third Temple. By giving prominence to a minority opinion, we make the ultimate expression of loving your fellow Jew. That is, even if I don’t agree with you, your opinion, when properly formed within a Torah framework, is important. That is why Hillel’s Korech sandwich is incorporated as a step in the seder and that is why it is a rememberance of the Temple. May we all merit to see that Temple rebuilt, speedily, in our days.
Why do you say that he did not embody the concept of “loving your fellow jew”?
I think Hillel did not embody the concept of “loving your fellow Jew” at all. His love was much less self-involved than than. The famous story the contrasts his personality with that of Shammai’s involved a *non-Jew* to whom he showed respect and patience.
