The MNCC Archdiocese was founded in 1649 by Rome as three separate dioceses within Mexico. These dioceses formed the archdiocese in 1790. During the Mexican Revolution, the Catholic church was split into two factions. Half were on the Federal side, which lost the conflict, and all of their clergy and bishops were expelled from Mexico. This Archdiocese was on the winning side and was named the National Catholic Church of Mexico by President Plutarco Calles in 1928.

The MNCC formed a friendship with Roman Catholic bishop Carlos Duarte Costa of Brazil who had separated from Rome due to Pope Pius XIII signing a concordat with Adolf Hitler in 1943. Intercommunion was signed between the two Catholic Archdioceses. We have worked together for many years in many areas of the Americas. The MNCC is a founding member of the Worldwide Communion of Catholic and Apostolic Churches that was founded by the successor of Bishop Carlos Duarte Costa, Bishop Luis Mendez Castillo.  There are two Communions founded by Bishop Luis Mendez Castillo.  Our Communion is very Catholic and holds fast to the True teaching of the One Holy Catholic and Apostolic churches and believes in the fullness of God's authority as spoken through his Holy and infallible Word that came to us from the Apostles of Jesus Christ. We literally can trace our church all the way back to Jesus Christ and His Apostles through our unbroken Apostolic lines of succession.
