The authors of these treatises decide unanimously in favour of a negative and indirect rather than a positive and direct
infallibility, inasmuch as in her general discipline, i.e. the
common laws imposed on all the
faithful, the
Church can prescribe nothing that would be contrary to the natural or the
Divine law, nor prohibit anything that the natural or the
Divine law would exact. If well understood this thesis is undeniable; it amounts to saying that the
Church does not and cannot impose practical directions contradictory of her own teaching.
Infallibility is directly related to the teaching office (
magisterium), and although this office and the disciplinary power reside in the same
ecclesiastical authorities, the disciplinary power does not necessarily depend directly on the teaching office. Teaching pertains to the order of
truth; legislation to that of
justice and
prudence. Doubtless, in last
analysis all ecclesiastical laws are based on certain fundamental
truths, but as
laws their purpose is neither to confirm nor to condemn these
truths. It does not seem, therefore, that the
Church needs any special
privilege of
infallibility to prevent her from enacting
laws contradictory of her
doctrine. To claim that disciplinary
infallibility consists in regulating, without possibility of
error, the adaptation of a general
law to its end, is equivalent to the assertion of a (quite unnecessary) positive
infallibility, which the incessant abrogation of
laws would belie and which would be to the
Church a burden and a hindrance rather than an advantage, since it would suppose each
law to be the best. Moreover, it would make the application of
laws to their end the object of a positive judgment of the
Church; this would not only be useless but would become a perpetual obstacle to disciplinary reform.
From the disciplinary
infallibility of the
Church, correctly understood as an indirect consequence of her
doctrinal infallibility, it follows that she cannot be rightly accused of introducing into her discipline anything opposed to the
Divine law;
