Throughout the history of messianic groups it has been found that some of its characteristic are that of, the separation from society, break rules, and deny any authority for the purpose to distinguish and isolate themselves from the disorder and immorality of society, trying to protect the "chosen ones" from a great catastrophe that is coming very soon, in a matter of five or ten years.
Examples of events with tragic outcomes are many, which are lead by charismatic leaders who offer alternatives to avoid the contamination of the evils of the global society, leading their followers to suffer all kinds of sacrifices, humiliation and in many cases end their lives.
Perhaps the most recent event to memory is that of the religious sect of Heaven's Gate, which was led by Marshall Applewhite that on March 26, 1997, police in San Diego, California, discovered the bodies of 39 of its members poisoned with cyanide, whom all of them had committed mass suicide because they believed that the comet Hale-Bopp was followed by an alien ship which they wanted to get onboard on.
The greatest tragedy of this kind occurred in 1978, in Guyana, where James Warren a.k.a. "Jim Jones", who was the leader of the Peoples Temple cult, caused the largest mass suicide in history where 914 people died which 200 out of that were children.
The New Jerusalem was founded in the state of Michoacan, which is located in the southern part of Mexico, where in 1973 the peasant Gabina Romero, claimed to have seen the Virgin Mary and received a message that she need to speak with pastor Nabor Cárdenas, and create a penitent town to so save themselves from an inevitable tragic fate that the world will face.
Cardenas then left the Catholic Church and became Pope Nabor, cult leader, and Romero became Mother Salome, the visionary who constantly received messages from the Virgin Mary, but then throughout the years disagreements arose from other visionaries who succeeded Mother Salome.
The purpose of the founders of the New Jerusalem was to be saved from the apocalypse, which was first announced to be in 1980, then in 1988 and the last time was in 2000.
