Thought this video relating to the history of Halloween, was both informative, and fun to watch...
My favorite time of year -- Halloween. There have been many varying stories behind the origin of Halloween, and this video shares a bit of them.
I have Christian friends who believe it to be a night of evil, and often don't partake of the 'holiday,' and instead...have separate functions at their churches. When I followed Christianity, I never viewed it as a dark and 'satanic' holiday, and what is interesting to note while viewing the video, is that Christianity sort of 'redefined' it away from its pagan roots. Not at all surprising.
Hope you choose to watch the video...it's pretty interesting. Happy Halloween!
