Question: How many years was Calles predecessor President? Passage:President Álvaro Obregón and his successor Calles, as well as other politicians, wanted the revolutionary government to restrict and terminate the Catholic Church in Mexico. In February 1925, armed intruders calling themselves "Knights of the Order of Guadeloupe" occupied the church of María de la Soledad in Mexico City where , a Freemason and former Catholic priest, proclaimed himself the future patriarch of a new national church; parishioners attacked the interlopers and rioted the next day; similar riots were incited when other churches in Mexico were occupied by armed intruders that month. These armed intruders occupying churches induced fear of anti-Catholic persecution that led to the formation of the National League for the Defense of Religious Liberty (LNDLR) a militant Catholic defense organization. Official favoritism of a national church enraged revolutionaries who saw this as a "violation of state '" with potential to faction the revolution, so Calles stopped his support of after about 3 months. Nevertheless, the government failed in 1925 to orchestrate Pérez's consecration by a visiting Eastern Orthodox bishop, but in 1926, North American Old Roman Catholic Church Bishop Carmel Henry Carfora consecrated Pérez, Antonio Benicio López Sierra, and Macario López Valdez as bishops. In 1927, López Sierra established an church in San Antonio, Texas, where Archbishop Arthur Jerome Drossaerts, of the Roman Catholic Archdiocese of San Antonio, called the ' (Spanish for schismatics) "designing proselytizers of the sects supported by Calles and the Mexican government, that archenemy of all Christianity;" and in 1929, López Valdes established an church in Los Angeles, California.
