The Church, cont'd: "The will to fulfill all God's commandments is, and must be, present in all of them. Such a wish implicitly includes the desire for incorporation with the visible Church: for this, though they know it not, has been commanded by God. They thus belong to the Church by desire (voto). Moreover, there is a true sense in which they may be said to be saved through the Church."
"Hence, too, that meaning of the sacred dogmas is ever to be maintained which has once been declared by Holy mother Church, and there must never be any abandonment of this sense under the pretext or in the name of a more profound understanding."
"“A theologian," says St. Augustine, “who is humble, will never teach anything as true Catholic doctrine, unless he is perfectly sure of the truth which he asserts. If he is corrected in anything in which he erred, he thanks for the correction, because his only desire is to know the truth." (Epist. ad S. Hier. 73 n. 1.)
""Those who have learned theology well," says St. Basil, “will not allow even one iota of Catholic dogmas to be betrayed. They will, if necessary, willingly undergo any kind of death in their defence." (Apud. Theod., lib. 4, Hist. Eccl., c. xvii.)"
