Writing in the Herald (behind the paywall), Glynn Cardy shows that not all Christians are pouty-faced over Halloween:
The God I believe in - full of life, love and laughter - joins me as I giggle at ghosts and groan at the horror genre. To take such things seriously, to give them a "real" presence, allows them too much power.
Halloween is a day to celebrate the imagination, and to become for an evening something mysterious and strange.
It's a day to rejoice in make-believe. It's a day to thumb our noses at the real world and go skipping off with winged horses and fairy folk. There is a reality to fiction and a value in fantasy that is wonderful and God-given.
By contrast, Christians of the pouty-faced variety seem to be ruled by fear - fear not just that the things we laugh at on Halloween are real, but also fear that they are not, and that nothing bad will happen for mocking them. After all, if ghosts, goblins, ghouls and evil spirits aren't real, and people aren't punished for thinking that, what might that imply about their god...?
