The government rejects exercise of any authority by organs of the Catholic Church outside China after 1949, the year communists gained power over all of mainland China. CPCA, which was founded eight years later, thus does not recognize the proclamation of the dogma of the Assumption of the Blessed Virgin Mary by Pope Pius XII in 1950, canonizations from 1949 onward (e.g. the canonization of Pope Pius X), Vatican declarations on even well-established devotional piety (e.g. on the Sacred Heart of Jesus or on Mary as Queen), and the Second Vatican Council (1962–1965). In practice, however, the Catholic Church in China uses Chinese translations of the documents of the Second Vatican Council, of the 1983 Code of Canon Law, of the 1992 Catechism of the Catholic Church (revised in 1997) and of the 1970 Roman Missal. These had at first to be imported from Taiwan and Hong Kong, but have been printed locally for some years.
