Tensions also existed between the Roman Catholic Church and the post-Revolution Mexican government. Severe restrictions on the rights of the Church and members of the clergy were written into the country's 1917 constitution that led to the eruption of the Cristero War in 1926. In 1992 the government reestablished diplomatic relations with the Holy See and lifted almost all restrictions on the Catholic Church. This later action included granting all religious groups legal status, conceding them limited property rights, and lifting restrictions on the number of priests in the country. However, the law continues to mandate a strict separation of church and state. The constitution still bars members of the clergy from holding public office, advocating partisan political views, supporting political candidates, or opposing the laws or institutions of the state.
