Viva Cristo Rey!
“¡Viva, Cristo Rey!” was the resounding battle cry of the Cristeros in their struggle against the violent imposition of a secularist, anti-Catholic, anti-clerical state in Mexico during La Cristiada (1926-1929), a war described by Graham Greene as “the fiercest persecution of religion anywhere since the reign of Elizabeth.”
“¡Viva Cristo Rey!” was also the final confession on the lips of Blessed Miguel Agustín Pro, a martyr of the Cristeros war. He was not a resistance fighter but a Catholic priest of wit and courage who selflessly ran a clandestine ministry during the treacherous reign of President Plutarco Calles. In 1927, Father Miguel was falsely charged and sentenced to death without due trial for the attempted assassination of Mexico’s former president, President Álvaro Obregón. The photographs of his execution were ordered by President Calles and were intended to show the cowardly death of a Catholic priest. Ironically, what has been seared into our collective historical memory is the very opposite of what Calles intended. The photographs immortalize an otherworldly truth. - from Sr. Theresa Marie Chau Nguyen, O.P., Ph.D. (https://www.usccb.org/committees/religious-liberty/viva-cristo-rey)
