'A true Catholic is he who loves the truth revealed by
God, who loves the Church, the Body of Christ, who esteems religion, the
Catholic faith, higher than any human authority, talents, eloquence,
and philosophy; all this he holds in contempt, and remains firm and
unshaken in the faith which, he knows, has always from the beginning
been held by the Catholic Church; and if he notices that any one, no,
matter who he may be, interprets a dogma in a manner different from that
of the Fathers of the Church, he understands that God permits such an
interpretation to be made, not for the good of religion, but as a
temptation, according to the words of St. Paul: "For there must be also
heresies; that they also, who are reproved, may be made manifest among
you." (I Cor. xi. 19) "And indeed, no sooner are novel opinions
proclaimed, than it becomes manifest what kind of a Catholic a man is;"'
