I’m going to hold off before “weighing in” – it’s way too early J
Suffice to say that most supposed origins of the holiday are wishful thinking at best. Virtually all our modern Halloween traditions come from right here in the good ol’ USA and date no earlier than the early 1900’s. There are a very few vestigial remnants from pre-Christian times (mainly from Pomona celebrations brought to the Celtic lands by the Romans)
Yes, the original holiday is Samhain/Samhuain/Sauin (depending on where you’re from; Ireland, Scotland, or Man - though Man also has Hop Tu Naa), but , as mentioned, most traditions supposedly associated with it are wishful thinking from particular churches/pastors with an agenda with “research” so shoddy, it’s scary (pun intended).
For those not born in this country, the American holiday of Halloween must be a curiously strange thing indeed! Something like modern Halloween, when it’s so intrinsically not at all a part of one’s cultural heritage, must be somewhat confusing and hard to grasp. I imagine it would be something like trying to get all of America to celebrate say, the Hindu festival ‘Diwali’ – sure, we could all do it, but hardly anyone would really understand it; it’s not part of our culture. Sadly, American cultural holidays have a funny way of permeating most other cultures, I mean, is Halloween really celebrated in Asia?? Seriously?? Does it really need to be??? Why???? I suspect for the sole purpose of generating lots of revenue for someone somewhere.
Samhain/Halloween is to some people a very spiritual and magickal time of the year; for some it’s a time of fun and candy, perhaps a way to celebrate Fall in general; others perhaps are not quite sure what to make of it and prefer to steer clear of it, but however you wish to celebrate it….or not – Halloween is only ‘evil’ if one chooses to make it so.
