services of his particular belief. And a Catholic who thinks that
because a Protestant friend can accompany him to Catholic services, he
too should return the compliment and accompany his friend to Protestant
worship, has a faith that needs immediate toning up to the standard of
Catholicity; he is in ignorance of the first principles of his religion
and belief.

A Catholic philosopher resumes this whole matter briefly, and clearly
in two syllogisms, as follows:

(I.)
Major. He who believes in an infallible teacher of revelation cannot
consistently listen to any fallible teacher with a view of getting more
correct information than his infallible teacher gives him. To do so
would be absurd, for it would be to believe and at the same time not
believe in the infallible teacher.

Minor. The Catholic believes in an infallible teacher of revelation.

Conclusion. Therefore, the Catholic cannot listen to any fallible
teacher with a view of getting more correct information about revealed
truth than his Church gives him. To do so would be to stultify himself.

(II.)
Major. He who believes in a fallible teacher--private judgment or
fallible church--is free, nay bound, to listen to any teacher who comes
along professing to have information to impart, for at no time can he
be certain that the findings of his own fallible judgment or church are
correct. Each newcomer may be able to give him further light that may
cause him to change his mind.
