The Second Ecumenical Council of the Vatican, commonly known as the or , addressed relations between the Catholic Church and the modern world.

History of the Catholic Church in Mexico
The Vatican likely sensed a sea-change and in 1990 John Paul II visited Mexico, his first since 1979 for the Puebla conference of Latin American bishops. After the announcement of his intentions, the Mexican Minister of the Interior ("Gobernación") stated flatly that the government would not amend Article 130. Nonetheless, the Mexican government began moves to normalize diplomatic relations with the Vatican. The pope's second 1990 trip in May put increased pressure on the Mexican government to take steps to normalization, particularly after the Vatican and the Soviet Union did so that year. Although Salinas planned a trip to the Vatican in 1991, the Catholic hierarchy in Mexico did not want normalization of relations with the Vatican without discussion of significant changes to the constitution.
