Wikipedia, the on-line encyclopedia, has this to say about Halloween: “The word Halloween is first attested in the 16th century and represents a Scottish variant of the fuller All-Hallows-Even ("evening"), that is, the night before All Hallows Day. Although the phrase All Hallows is found in Old English (ealra hálȝena mæssedæȝ, the feast of all saints), All-Hallows-Even was not attested until 1556.
We often decorate our house with scary “nature things” like spiders & webs, lizards, snakes, mice, birds, bats - and not “death and demon” related items most often found in Halloween-themed stores. We carve real pumpkins or put out the plug-in type. We hand out candy or tiny Christian toys and witnessing tracts that are family-friendly. For the past couple of years (as an empty-nester) I take my two dogs out and walk the neighborhood, visiting with those we meet. You can make October 31st a night to talk about death, eternity, and how Jesus laid His life down for them.
