Every year, at Halloween, St. John the Divine is the host of a strange event called “The Grand Procession of the Ghouls”. It is basically a parade taking place right inside the sanctuary of the Cathedral where people dressed in costumes of demons, ghouls, monsters and other creepy things, walk around to macabre organ music.

This thing resembles strange rituals held behind closed doors by occult groups. Outside of the great number of costumes representing demons and Satan, some costumes seem to make a mockery out of Christianity.
