I can understand the idea behind not using matches, but I would say that it really is up to the practitioner. What makes or breaks a ritual is how the practitioner feels about that ritual, ie: if they think that the sulfer will "taint" the energies they are drawing upon, and they still use matches, then, by their own will, will introduce that "taint" themselves. Conversely, if they don't feel that the matches affect it one way or the other, odds are it won't.
I'd say, it's easy enough to get around, if it bothers someone.. simply allow the match to burn down for a few seconds, the sulfer will burn away rather quickly.. imagine it as a self-clensing fire, if you will... then you simply have flame on a wooden stick. Like Tarty mentioned before, you could transfer the flame to something else as well. :)
I do, however, have to agree somewhat with the concept of using a lighter... at least one that's also used to light your cigerettes. If you must use a lighter, like any tool, it should be the *only* thing it's used for.
Btw, Thanks for the compliment Grey! It was nice to be referred to as "one well versed in lore" :)
