Events and decisions in our lives fall into three categories—biblical, nonbiblical, and unbiblical.
Halloween is nonbiblical: God’s word does not command it, which would make it biblical, or forbid it, which would make it unbiblical. However, Scripture does teach us what would be biblical to do today, such as using the day for church outreach events, getting to know your neighbors so you can build relationships for the gospel, and spending fun time together as a family. And it teaches us what would be unbiblical to do today, such as engaging in occult practices or anything that would glorify Satan.
