Rivera was born in Las Palmas de Gran Canaria, Canary Islands, Spain. He is most notable for his statements about his time as a Catholic priest and the inner workings of the Catholic Church. Most of these statements are fiercely disputed by the Catholic Church and others and Rivera was not able to provide compelling evidence in support of this statement. An exposé by Gary Metz in Cornerstone magazine as well as another one in Christianity Today questioned many of Rivera's statements about his life, alleging that he was a fraud. The two conflicting versions are summarized below.
Rivera's account
According to Rivera, he was brought into a seminary in 1942 when he was 7. 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. When visiting his mother's grave, Rivera vowed to find answers to the truth. After education at an unnamed Catholic seminary, he was sent to destroy various Protestant organizations and discredit Protestant leaders, but Rivera says that he became disillusioned upon finding that the Vatican was behind Freemasonry and that its reverence of the Virgin Mary was contradicted by the Bible. In 1965, at an Ecumenical Conference in a Guatemalan stadium, he denounced the Catholic Church to an audience of 50,000 people. Rivera says that the Jesuits then sent him to a top-secret psychiatric hospital in Spain to make him embrace the Catholic faith—what Rivera referred to as "recanting his faith." Here he says that he was tortured and given poison until he nearly died, eventually being put into an iron lung because his lungs had broken down from the abuse. According to Rivera, he was "nearly at death" when he asked Jesus to forgive him and was miraculously healed. Rivera said that a senior Jesuit attempted to persuade Rivera to return to Catholicism, but instead was himself persuaded to give Rivera the passport and papers he needed to escape Spain. Afterwards, he flew to London and saved his sister María, a nun, after she nearly died in a convent of an unspecified illness or injury.
''Cornerstone'''s account
According to the Cornerstone exposé, Rivera had a 'history of legal entanglements' including fraud, credit card theft, and writing bad checks. Warrants had been issued for his arrest in New Jersey and Florida, and he was wanted by the Spanish police for 'swindles and cheats'. While in the U.S. in 1967, he said he was collecting money for a Spanish college, which never received this money. The details of his religious statements changed over time. For example, in 1964 he said that he had left the Catholic Church in July 1952. Rivera later put the date at March 20, 1967 - an almost 15-year discrepancy. Despite this second statement of conversion from Catholicism in March 1967, Rivera was still promoting Catholicism in a newspaper interview of August that same year. Although supposedly placed involuntarily in the sanatorium where he said he was nearly murdered in 1965 and held there for three months, he gave the date of his release as September 1967. This leaves a period of more than a year unaccounted for in Rivera's narrative. The document exhibited by Rivera to prove his status as a Catholic priest was fraudulent. The Catholic Church says his statement of having been a Jesuit priest, or another statement that he was a bishop, are not true. He had only one sister in London, she was not a nun but a maid working in a private London home, she did not live in a convent, so the statement that his sister the nun nearly died in a convent in London was a lie. 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.. In his narrative, Rivera said that he was a priest living in Spain in 1963. Cornerstone also questioned Rivera's statement to various degrees, including three doctorates, reporting that his known chronology did not allow enough time to have completed these degrees. 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 also made several allegations about Islam, which he did not offer proof for. This includes allegations that Muhammad was manipulated by the Catholic Church to create Islam and destroy the Jews and other groups of Christians, and that Muhammad's first wife Khadijah bint Khuwaylid, was actually a Catholic nun in an Arabian monastery, who was told by a bishop to marry Muhammad and create Islam. Rivera also alleged that the Vatican staged an apparition at Fátima to cultivate favor with Muslims. He further says that it also staged the 1981 assassination attempt on Pope John Paul II using a Muslim as the marksman "to guilt-induce the Muslim world, bringing them still closer to the Catholic faith!"
Presence in "Chick Tracts"
Six of Jack Chick's comics feature Rivera specifically: Alberto, Double Cross, The Godfathers, The Force, Four Horsemen, and The Prophet. He also wrote the introduction to Chick's republication of The Secret History of the Jesuits by Edmond Paris.
Death
Rivera died in 1997 of colon cancer. His ministry was taken over by his widow, Nury Rivera. A popular conspiracy theory alleges that Rivera died due to food poisoning. According to cemetery records, he is buried in Section Moore L-14 #3 at Rose Hill Cemetery in Tulsa, Oklahoma.
