The Bible tells Christians specifically not to adopt the practices of pagans and make them a part of worshipping Him. He tells us in His word how he wants to be worshipped and co-opting a pagan holiday and pretending they’re Christian is not what He told us to do.
No one in our family worships Lucifer. We worship One Lord. I don’t even really care when or where Halloween originated because at the end of the evening we’re too busy praising our children for the great manners they’d displayed; how they shared what they received and how much fun we had! And as we inspect and pour through their bags of candy, we debrief with the kids just like we do every evening in our home. And we *laugh* and talk about what great costumes we saw, who dressed like this or that, etc. It’s all about families having fun and being silly one night a year and still coming home knowing there is One Lord for our house.
So in your face, Devil. This family refuses to sit home and hand this day over to the evil one; nor will we provide him with any satisfaction. Maybe staking claim to something once owned by the devil and turning it into something joyful and fun is something to consider — instead of turning your lights out and sitting in the dark.
