 The magisterium of the papacy is according to Parente, of divine and not human origin.He used the papacy not only to teach the truth but also to bring together all Christians separated from the Holy Roman Catholic Church, but not by reducing basic the truth entrusted to the Church.Pius XII according to Parente, set firm pointers in mariology (Munificentissimus Deus and Fulgens corona), liturgy (Mediator Dei), the definition of the Church, ("Mystici corporis"), biblical exegesis ("Divino afflante Spiritu"), and, the application of papal infallibility (with the Dogma of the Assumption).
