Alberto Magno Rivera Romero (September 19, 1935 – June 20, 1997) was an anti-Catholic religious activist who was the source of many of the theories about the Vatican espoused by fundamentalist Christian author Jack Chick.

An exposé by Gary Metz in Cornerstone magazine[1] as well as another one in Christianity Today[2] questioned many of Rivera's statements about his life, alleging that he was a fraud.

Two years later, as his mother was dying, she saw "ugly creatures" coming at her deathbed, and faced a "Christless eternity" because of her Catholic faith.

According to the Cornerstone exposé,[1] Rivera had a 'history of legal entanglements' including fraud, credit card theft, and writing bad checks.

In an employment form dated 1963, Rivera stated he was married to Carmen Lydia Torres, and the couple had two children in the U.S.

Rivera allegedly admitted that he had received these degrees from a non-accredited entity sometimes referred to as a diploma mill located in the state of Colorado.

Rivera said that the Jesuit order was responsible for the creation of communism, Islam[4][5] and Nazism, and causing the World Wars, recession, the Jonestown Massacre, and the assassinations of Abraham Lincoln and John F. Kennedy (a Catholic).

Rivera also alleged that the Vatican staged an apparition at Fátima (named after Fatimah, daughter of Muhammad) to cultivate favor with Muslims.
