Mixed — ranges from innocent costume fun to genuinely dark occult celebration. Three defensible Christian positions. What you actually do matters more than the calendar date.
Position 1: Avoid entirely — based on Ephesians 5:11 and associations with death and the occult. Coherent and defensible; becomes problematic as law binding on all Christians.
Position 2: Redeem and engage — community opportunity, innocent fun, missional contact. 1 Corinthians 10:25-27 provides framework. Pagan history does not determine current meaning.
Position 3: Participate selectively — trunk-or-treat, non-dark costumes, community connection while avoiding glorification of evil. Most common evangelical position.
The question is not Halloween yes or no — it is what you are actually doing. Children in superhero costumes collecting candy from neighbors is not spiritually dangerous. Horror movies glorifying the demonic and engagement with actual occult practice are different questions entirely. Romans 14:5-6 affirms believers can honor God differently on different days. See the Biblical Discernment Guide for the full framework.

Questions about sin fall into two categories: things explicitly called sin in Scripture, and disputable matters (Romans 14-15) where Christians with different convictions should respect each other's consciences. Even when something isn't explicitly sinful: Does this practice reflect Christ's lordship over all of life (Colossians 3:17)? Is it beneficial — not just permissible? (1 Corinthians 10:23). Score: 50/100 Mixed.
