There is now a lot of good literature readily available on the liturgical changes since Vatican II and writers openly critical of these changes now extend far beyond the confines of the SSPX and the sedevacantist world. The same cannot be said of the debate on religious liberty and Vatican II where, with the notable exception of Fr. Bryan Harrison, all the controversy on this subject seems to emanate from the SSPX milieu. Hopefully, this will change soon but in the meantime Opuscula is striving manfully to help plug that gap and with his latest posts (which can be read
here) is taking us to the heart of the pre-Vatican II debate, namely the promulgation by Pope Pius IX of the
Syllabus of Errors in 1864. The controversy over religious liberty centres on whether or how this document can be harmonized with
Dignitatis Humanae.
According to Pope Pius IX the
Syllabus of Errors was "raw meat, needing to be cooked" and from the begininng there have been heated discussions between those who like it rare and those who like it well done and some who quite frankly like it raw. One of the most curious things about the
Syllabus was that the concept of "tolerance" (i.e. tolerance of error to achieve a greater good or avoid a greater evil) was not once mentioned and this had to be "corrected" later by Pope Leo XIII. Certainly today to speak of the Catholic state without even mentioning tolerance is a bit like talking of the ark without the flood but even back then the omission caused misunderstandings and controversy. Immediately Msgr Dupanloup, Archbishop of Paris, wrote an explanation of the
Syllabus in which he propounded his famous "thesis/anthithesis" rule of interpetation which introduced, though under different terminology, the theory of "tolerance" later to be taken up by Pope Leo XIII. Six hundred bishops wrote to thank him, a sign of the percieved need for some such explanation. However, at the time and ever since there have been other Catholics who have condemned Dupanloup's intervention as seeking to evade the plain wording of the
Syllabus and hence evidence of liberal inclinations. It was particularly in France that this debate ignited and the SSPX have been inspired by this strict, anti-Dupanloup school. There were many great and distinguished names amongst this group such as Cardinal Billot but it is important to know that they did not represent the entire body of pre-Vatican II thinking on the subject. The Jesuit Vermeersch for example, represented the opposite school and wrote an entire book titled
Tolerance. Likewise for the famous theologian Pohle whose article on religious tolerance for the 1913 Catholic Encyclopedia can be read
here. Over time the pre-Vatican II Popes seem to have recognised more explicitly the need and advisability for the tolerance of false religions, even in a Catholic state, culminating perhaps in Pope Pius XII's talk to Italian jurists in 1953. Speaking of the public, and not just private, practice of other religions he said:
Could it be that in certain circumstances He would not give men any mandate, would not impose any duty, and would not even communicate the right to impede or to repress what is erroneous and false? A look at things as they are gives an affirmative answer...Hence the affirmation: religious and moral error must always be impeded, when it is possible, because toleration of them is in itself immoral, is not valid ‘absolutely and unconditionally.…The duty of repressing moral and religious error cannot therefore be an ultimate norm of action. It must be subordinate to ‘higher and more general’ norms, which ‘in some circumstances’ permit, and even perhaps seem to indicate as the better policy, toleration of error in order to promote a ‘greater good.’
This "affirmation" that the Pope criticises is one I think that is to be found, at least implicitly, in the old debates on the subject from the anti-Dupanloup school as is also the reluctance to embrace the meaning of the first sentence. Anyway, this is one area where some historical background is important in understanding the to and fro of the arguments and the history is still not well known in the English speaking world.
