halloween's origination is of a pagan nature where people would wear costumes to ward off ghosts & light bon fires. it was all part of a ritual to welcome the harvest. so "pagan" is the main word here. that's definitely not of God! sure, it has softened a bit in america. giving kids candy & gifts is fine. so clearly, any involvement having to do with those things God said are evil, yes, it is evil to celebrate halloween that way. i myself, have never decorated for any holiday in my life nor have i celebrated halloween ever. i celebrate Christmas & Resurrection day spiritually. other holidays, i celebrate just for what it is, nothing added.
