Alberto Rivera
Chick's anti-Catholic comic book series based its stories off the testimony of a man named Alberto Rivera. He claimed to be an ex-Jesuit from Spain, although there is no evidence to support this. Rivera would go on to allege the Catholic Church used the Jesuits as secret police to do everything from the creation of Islam, to the assassination Abraham Lincoln.
The Crusaders Series, (1979-2011)
Through webs of conspiracy theories, these comic books lay most historical tragedies at the hands of the Church, such as the Jesuits being behind the rise of both Communism and Nazism. The comics also state that sacraments like the Eucharist and Reconciliation were created to allow the Pope to wield more secular power.
