I had to go through through The Lanes, Brighton's old town, yesterday evening, it was full of ghouls and witches getting drunk on the streets, they weren't children but young adults, I was tempted to cry out, "Burn the witch", but that seemed a bit protestant outside of Germany.
When I was young Halloween was pretty low key, on a par with St Agnes' Eve , learning from our American cousins it has grown in retail significance.
I wonder if there is also something hidden going on, a yearning for "communion" with the dead. With no heaven or purgatory the dead become an object of fun or something on which to focus our hidden fears. In Catholic countries Halloween was a time for a certain un-Christian cult of the dead, like Carnivale it was a time of misrule but it was balanced and contrastred by All Saints day which offered a vision of the future and All Souls Day which offered the present reality of the faithful departed dependant on Christ and on us and the saints.
I am intrigued by why the misrule anarchic aspects of Christian Feasts are kept, when the feast itself is neglected.
