Move Halloween?

Not quite, it has it origins in Celtic druidism and predates Christianty by at least 5 decades
All the Christian's did was take a pagan holiday and place a "christian" moniker over it

The rituals, the pictures, the severed heads with the souls still burning (we call them Jack-o-lanterns) they all kept

Feel free to believe what you want, but if you want to convince me I'm wrong (wouldn't be the first time) then show me the verses which teach the doctrines that "all hallows" is based on

Whatever you say sir. Whose to say that something founded in paganism cannot be turned into something good? The blood of Jesus Christ washes away all sin, or have you forgotten that, too? I don't have to show you jack. I just proved it.
