October 31 is All Hallows Eve. Over the years it has been corrupted into Halloween. The Church of England Diocese of Manchester is promoting a campaign called Halloween Choice. It's not intended to eliminate all the gruesome "fun" of Halloween, but rather to promote the positive and Christian aspects of All Hallows Eve and lobbies retail outlets to provide more diversity in their marketing.
halloweenchoice.org has more information. I think it would be nice to see this campaign taken up by the church in other areas, including Australia.
