The holiday of Chanukah raises a number of questions:
The truth is, had the Maccabees not found the small cruse of pure olive oil, they could have used any oil. While it is best to use olive oil, any oil that burns well may be used in the Temple Menorah.
The miracle of Chanukah could have been the Menorah burning all eight days with ‘miracle oil.’ But while ‘miracle oil’ is as good as any other oil, it is not olive oil. Thus the miracle of the first day of Chanukah was not the burning of ‘miracle oil,’ but that the Maccabees found ritually pure olive oil. This discovery was quite unexpected, and it enabled them to light with the optimal type of oil.
In addition, since the majority of the nation at the time was ritually impure, the Maccabees could even have used impure oil. The miracle of finding the cruse of olive oil thus allowed them to fulfill two hidurim: lighting on the first day with olive oil, and lighting with ritually pure oil. We commemorate this miracle by similarly performing two hidurim, with every family member lighting, and lighting multiple candles.
But why was there no comparable miracle with the Menorah itself ? Why didn’t the Maccabees also find a gold Menorah in the desecrated Temple?
The Menorah corresponds to the material state of the Jewish people. It is a vessel for holding the oil. The olive oil, on the other hand, is a metaphor for the nation’s inner spirit.
While it is fitting that the external vessel should be aesthetically pleasing, there are times when the physical reality is harsh and discouraging. During such times, we make do with what we have, even if it means lighting with a Menorah improvised out of iron rods.
However, the spirit — the oil that nourishes the inner flame — must always remain spiritually rich, with all of the hidurim of purity and holiness. This is an important part of the message of Chanukah: the miracle occurred, not with the Menorah, but with the oil. We may suffer physical hardships and deprivation, but our inner spiritual life should always shine with a clear and pure light.
