Abstract
The Mexican Reforma is often considered a classic example of the power struggles that occurred between church and state throughout the nineteenth century. However, since in this case both sides claimed to be Catholic, the most important battles in Mexico were actually intra ecclesiam. Ultimately, it was a fight over access to the sacraments that drove Mexico into civil war, transforming both the Church and society in the process. The current debate in the United States over allowing public figures who violate Church teaching to receive Holy Communion should be considered within the context of the Mexican experience.
