The English word goblin originated from an ancient Greek word, pronounced kobalos, which meant a malignant (dangerous, destructive) spirit i.e. a demon. Should Christians pander to demons by observing demonic festivals? To most Christian-professing people, the answer is an emphatic no. And yet millions of Christian-professing people do just that every year at Halloween.
"Ye cannot be partakers of The Lord's table, and of the table of devils"
The respected and authoritative Encyclopedia Britannica has a startling account of the origin of demonic Halloween that degenerated, even further, from a pagan Church of Rome "All Saints Day" (the Church of Rome has martyred true of saints of God for centuries and will do so even more just prior to Christ's return) to a blatantly Satanic festival.
"Halloween, in medieval times All Hallows Eve, a holy or hallowed evening observed on October 31, the eve of All Saints Day; in modern times, it is the occasion for pranks and for children requesting treats or threatening tricks."
"In ancient Britain and Ireland, the Celtic festival of Samhain was observed on October 31, the end of summer. The date was also the eve of the new year in both Celtic and Anglo-Saxon times and was the occasion for one of the ancient fire festivals when huge bonfires were set on hilltops to frighten away evil spirits. The date was connected with the return of herds from pasture, and laws and land tenures were renewed. The souls of the dead [see What Happens When You Die? and Where Is Your Soul?] were supposed to revisit their homes on this day, and the autumnal festival acquired sinister significance, with ghosts, witches, hobgoblins, black cats, fairies, and demons of all kinds said to be roaming about. It was the time to placate the supernatural powers controlling the processes of nature. In addition, Halloween was thought to be the most favorable time for divinations concerning marriage, luck, health and death. It was the only day on which the help of the devil was invoked for such purposes." (Encyclopedia Britannica, 15th Edition, volume 4, page 862)
And what about participating in activities based on paganism, witchcraft, demons, divination, and "seeking the help of the devil"? According to God's Word in The Holy Bible:
"But I say, that the things which the Gentiles [pagans in other translations] sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils. Ye cannot drink the cup of The Lord, and the cup of devils: ye cannot be partakers of The Lord's table, and of the table of devils." (1 Corinthians 10:20-21 KJV)
"There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, or an observer of times, or an enchanter, or a witch, Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer. For all that do these things are an abomination unto The Lord: and because of these abominations The Lord thy God doth drive them out from before thee. Thou shalt be perfect with The Lord thy God." (Deuteronomy 18:10-13 KJV)
