Halloween is originally a Christian Holiday, and the name "Halloween" was derived from the Old English word "Hallow" which means "Holy". Halloween is also known as "All Hallow's Eve", because the Holiday is celebrated on October 31, the day before the Solemnity of All Saints (November 1). It is said that a long time ago, the celebration of Halloween is sacred, and children dress themselves as their favorite Patron Saints to honor them and their holiness. Sadly, Halloween lost its sacredness, and children of today dress themselves as monsters, demons, witches and anything scary, and many people think of Halloween as a Pagan Holiday, instead of a Christian Holiday. What happened to the Christian Halloween? And who started the idea of dressing as monsters during Halloween?
