I think one of the most important questions we as Christians need to ask about Halloween is: What kind of fruit does it bear?
Think about. Fear, depression, introductory to divination, mischief, discord, rebellion.
Anyone ever heard of Devil's Night? That is what they used to call it or still do in my city. Some have switched to Angel's night to try to counteract all the mess that happens on DN. But anyway, they have to watch for homes not to be burnt down and have you all heard what happens in NY;Crips slashing people's faces.
This is the fruit borne by Halloween and is why I do not participate at all.
Look, Jesus said "you will know them by their fruit."
He wants us to produce good fruit, not just produce. Go look it up if you don't believe me.
