This past April, St. Augustine’s Press published Religious Freedom: Did Vatican II Contradict Traditional Catholic Doctrine? A Debate by Arnold T. Guminski and Father Brian W. Harrison (Pontifical Catholic U. of Puerto Rico). The publisher’s description follows.

One of the gravest and most divisive issues confronting the Catholic Church in recent decades – a major factor in an ongoing institutionalized rupture between Rome and at least half a million traditionalist Catholics – is the question of whether Vatican II’s Declaration Dignitatis Humanae can be reconciled with traditional Church doctrine on religious liberty.

In this spirited exchange of essays on a topic central to our understanding of justice and human rights, Arnold Guminski and Fr. Brian Harrison debate this difficult question. Guminski argues that DH teaches that there is (and always has been) a natural right not to be prevented from publicly propagating or manifesting non-Catholic religions, subject to the exigencies of a just public order, which is to be understood as not presupposing the truth of natural or any positive religion (including Catholicism), or any supernatural considerations. Harrison disagrees. In his view, DH nowhere teaches that it is always and everywhere unjust for civil authorities to presuppose the truth of Roman Catholicism in determining what restrictions a just public order allows.

According to Harrison, the central innovative feature of DH is its clearly implied prudential policy judgment, or norm of ecclesiastical public law, to the effect that in the modern world – so very different from the old Christendom – repression of the public propagation or manifestation of non-Catholic religions as such can no longer be justified by the requirements of the common good. Harrison argues that precisely because this undeniable reversal of the Church’s previous position belongs in the category of changeable prudential judgments, it does not constitute a doctrinal rupture with Catholic tradition. Guminski, on the other hand, contends that the doctrine of DH, properly understood, is inconsistent with relevant preconciliar doctrine. The latter, in his view, was never proposed definitively – i.e., infallibly.

Both authors agree to a comprehensive theory of the nature and scope of the Church’s inherent coercive power as it pertains to liberty in religious matters. They agree that this power is limited to the imposition of spiritual penalties and temporal penalties, and that the Church’s inherent coercive power nevertheless must be exercised within the limits of a just public order.
