Rafael Guízar y Valencia was a Mexican Catholic bishop born in 1878 in Cotija de la Paz. Following his ordination in 1901, he eventually served as the Bishop of Veracruz-Jalapa. During the Mexican Revolution, he faced intense political persecution, which forced him to live in hiding or exile for many years. To continue his ministry while avoiding authorities, he often used various disguises, such as working as a musician or a street seller, to secretly administer sacraments to the faithful.
