 During the 1920s, Mexico underwent a period of instability under the Plutarco Elías Calles administration who was seeking to limit the influence of the Catholic Church to modernize and centralize the state within the religious sphere of Mexican society. To protest the policies, the Catholic Church suspended all religious services, bringing about an uprising in Mexico. This uprising, or Cristero War, lasted from 1926 to 1929 and reemerged in the 1930s. On April 6, 1926 González had a vision in which God changed his name from Eusebio to Aarón and was later told to leave Monterrey where he and his wife served Saulo and Silas. On his journey, he preached near the entrances of Catholic churches — often facing religious persecution — until he arrived at Guadalajara on December 12, 1926. The Cristero Wars impacted both Catholic and non-Catholic congregations and preachers, especially evangelical movements. Small movements were attacked by the government and the Cristeros, resulting in a hostile environment for González's work.
