"Halloween was not the original name of this day. the Pre-Christian Druids and Celts of Northern Europe held a celebration every Nov. 2nd called "The Vigil of Shamhain", lord of death. They held the belief that Shamhain, the lord of death, was overpowering their sun god (Muck Olla), because the leaves were falling, the days were shorter and the weather was getting colder. Their belief was that Shamhain sent the spirits of those who had deceased over the past year into animals, because of the evil they had committed while alive. Then, on Nov. 2nd, the Vigil of Shamhain, those spirits would be released to go back and visit their homes and family members with acts of horror and evil. Therefore, in efforts of keeping these released evil spirits from coming to their homes, a ritual of this holiday included locking up various species of animals (including humans) in wicker cages and burning them alive, all in attempts of appeasing Shamhain and preventing the visitation of these evil spirits upon their homes!
Christians, desirous of their own fall celebration, refused to participate with the Druids, and established Nov.1st, one day earlier than the Vigil of Shamhain, as "All Hallow's Day" (recognizing/honoring christian martyrs and saints). In reaction to the Christians' action, the pagan/satanic worshippers counteracted "All Hallow's Day", preempting them by one day - October 31st, with their own celebration, "All Demon's Night." This festival evolved into the 'high holy day' of all opposing Christ(ianity) and was celebrated via incantations, sacrifice, satanic worship/rituals and horrors for all who opposed them. Finally in a horrid attempt to Christianize the paganistic holiday, the eve prior to "All Hallow's Day" became known as "All Hallow'en" (Oct. 31st) which was eventually shortened to "Halloween."

It's more important to follow Christ than tradition. The act of recognizing and participating in any of this day's festivities is, in fact, celebration. Stand for righteousness...and please God.
