“Can you roast marshmallows over a sacred fire?”
Young Fiona's plaintive question was no idle one.
We'd kindled our Fire of Meeting in the sacred grove on Friday night. All weekend, it had burned continuously, receiving prayers and offerings each morning. Then rain threatened to extinguish it.
(In the end, it didn't, but there was no knowing that at the time.)
So we added a burning log from the sacred Fire to the (non-sacred) fire that burns in the pavilion where people gather when weather's wet, thus (by "contagion") rendering it sacred, thus prompting Fiona's profoundly theological question.
To generalize: may sacral Fire be used for practical purposes as well?
All Fire is sacred, but—by the nature of things—we have to use it for practical purposes, too.
In the face of this paradox, the ancestors cut a deal with the Powers that Be: we maintain sacred Fires to embody, to epitomize, the sanctity of Holy Fire. These we treat with the utmost regard, as honored guests. No waste may be burned in them, only offerings.
Only by virtue of this, is it given to us to make practical use of fire as well.
(We need only look around us in the culture at large to see the dire results of the violation of this primal agreement.)
So: when sacred Fire is the only Fire available—as in this situation—is it permissible to use it for practical purposes—cooking, say—as well?
