This church converted into a parish catering to German Americans in 1871 when the larger Annunciation Church opened. The city's first black Catholic church was St. Nicholas, located in the Third Ward. In 1910 there were no Mexican Catholic churches in Houston. Some Mexicans were excluded from attending English-speaking Catholic churches. Mexicans who did attend found themselves discriminated against. In 1911 the Roman Catholic Diocese of Galveston brought the Oblates of Mary Immaculate, a series of priests intended to minister to the Mexican population of Houston. In 1912 Our Lady of Guadalupe Catholic Church, the first Mexican Catholic church, opened. Due to an increase in demand in Catholic services, oblates established missions in various Mexican-American neighborhoods. The Roman Catholic Church established Our Lady of Guadalupe so that white people accustomed to segregation of races would not be offended by the presence of Mexican people in their churches.

It originated as an oblate mission in Magnolia Park, on the second floor of the residence of Emilio Aranda. A permanent two-story building, funded
