Roman Catholic Christianity

Roman Catholic is the most popular religion in Mexico with 82.7% of the population associated with it. The Catholic Church in Mexico is a subset of the global Catholic Church headed by the Pope and is headquartered in the Vatican. Mexican Catholic history is divided into colonial and postcolonial history. During the military conquest of Mexico, efforts were made to evangelize the indigenous population of Mexicans, which led to the establishment of the episcopal hierarchy. After independence in the 19and century, a legal framework was established to promote the affairs of the Catholic Church. The established framework declaring Catholic as the only religion led to the Mexican Revolution which was won by the Constitutionalists which led to the restriction of the church. However, the Catholic Church will later embark on the construction of social facilities and the formation of a political party, the National Action Party. A new framework was then established which lifted some of the restrictions placed on the church. Currently, Mexico is the second largest Catholic country in the world with 18 ecclesiastical provinces and a total of 90 dioceses. The Catholic Church in Mexico has 15,700 diocesan priests and more than 45,000 people in the religious order.

In Mexico, 6.6% of the population belong to other Christian denominations, including Pentecostal, Evangelical, and other mainline Protestant Christianity. Evangelical Christianity is the most popular denomination forming 4% of the population while Pentecostals form 1.6%. Evangelicals in Mexico were born with British and American missionaries in the 19and century. Pentecostals in Mexico, like other evangelicals, adhere to the Bible as divine inspiration.

An atheist or agnostic person in Mexico is defined as anyone who does not literally practice the faith or adhere to any religion or practice any religious activity.
