The growing cult of the Holy Death is easily seen in many neighborhoods of San Luis Potosi, as the people create temples for the purpose of praying to the Holy Death.
The walls are painted with images of skeletons, and shrines are built on the sidewalks so that passers by can stop and worship them. This practice was started by the narco-traffickers, who are warring against each other and the police. In this cult, people call upon the Holy Death to commit acts of evil against their family members who have wronged them, or have not chosen to remain under Mexican Roman Catholic rule.
Some of our Christian friends here live in a neighborhood prevalent with the worship of the Holy Death. Some of their family members have turned against them and have called upon witches and witch-doctors to cast evil spells on them in order to force them back into Roman Catholicism. Every night, one of their daughters sees shadows roaming around her bedroom. She prays out loud asking God to remove the evil spirits, which He does, and she can finally sleep. One afternoon, her mother was putting clothes on the line to dry. Before she got finished, she went in the house for something and both she and her daughter saw some of the clothes being pulled off the line, but there was nobody there doing it. They prayed together and the evil spirit left. This is very common.
