Did any of the speakers take your approach?
Funny you ask. I just came back to make a correction to my post above. The summary in the link in your first post didn’t mention what Fr. Harrison said and so I decided to see what approach he took on the matter (I’ve read him on other topics before)–it turns out that in other articles he takes this same approach (I assume he did at this conference too). As I mentioned, this seems to also be the interpretation the Church has actually taken as found in the CCC, especially given how it incorporates those 19th century papal texts. Harrison also appears to do a good job of not confounding the issue of religious liberty with the issue of the relationship between the Church and State/Social Kingship of Christ. DH only deals with the latter in the brief “…leaves untouched…” sentence and a neutral passing statement about “special civil recognition.”
That being said, I would bolster Harrison’s argument a couple ways (he may do this in his longer books I have not read):
I think it’s important to show how the Church defines the common good and also show that it is the
raison d’etre for public authority. The common good is public authority’s special province and determines “the fixed limits within which it is contained.” (Leo XIII, Immortael Dei 13). That’s when and why it can interfere with man’s freedom.
The Church is clear that to serve the common good is why public authority exists:
CCC 1898 Every human community needs an authority to govern it.16 The foundation of such authority lies in human nature. It is necessary for the unity of the state. Its role is to ensure as far as possible the common good of the society.
Leo XIII, Diuturnum: But now, a society can neither exist nor be conceived in which there is no one to govern the wills of individuals, in such a way as to make, as it were, one will out of many, and to impel them rightly and orderly to the common good; therefore, God has willed that in a civil society there should be some to rule the multitude.
St. John XXIII, Pacem in Terris: 54. The attainment of the common good is the sole reason for the existence of civil authorities.
Pope Francis, Evangelii Gaudium: 240. It is the responsibility of the State to safeguard and promote the common good of society.
So what is the common good? Murray, for example, argued that public authority only had competency for what he called the “common peace,” which he said was a subset of the common good–this is the most minimum restraints on activity needed for coexistence. Pink adds natural reason/morality to public authority’s purview (saying it can only go beyond this with the delegation of the Church). The CCC (2109) explicitly rules out such exclusively naturalistic conceptions in the context of religious liberty and cites to two papal documents, from Pius VI and Bl. Pius IX, respectively, which
harshly condemned such a naturalistic approach to religious liberty. On the other hand, the common good also includes “the prosperity, or the development of the spiritual and temporal goods of society.” (CCC 1925). Notice the inclusion of the spiritual well-being of society. As St. John XXIII taught:
St. John XXIII, Pacem in Terris 57. In this connection, We would draw the attention of Our own sons to the fact that the common good is something which affects the needs of the whole man, body and soul. That, then, is the sort of good which rulers of States must take suitable measure to ensure. They must respect the hierarchy of values, and aim at achieving the spiritual as well as the material prosperity of their subjects.(42)
- These principles are clearly contained in that passage in Our encyclical Mater et Magistra where We emphasized that the common good "must take account of all those social conditions which favor the full development of human personality.(43)
- Consisting, as he does, of body and immortal soul, man cannot in this mortal life satisfy his needs or attain perfect happiness. Thus, the measures that are taken to implement the common good must not jeopardize his eternal salvation; indeed, they must even help him to obtain it.(44)
Man’s supernatural end and well-being need to be taken into account (see also CCC 2244).
In the 19th century the Popes were fighting against the Liberals/Rationalists/Naturalists who wanted to impose a liberty based on naturalist, indifferentist, and even anti-clerical and anti-Catholic principles for the purpose of diminishing or even destroying the spiritual prosperity of certain countries (since they denied any public value to spiritual things or even argued they caused public harm). This is the exact opposite of a liberty founded on man’s relationship to God and duty to seek the truth, and, because he is a social creature, limited by the needs of the authentic common good of the society to which he belongs, which is what DH and the CCC declare.
Since the measures needed to advance the common good vary by the circumstances (as the CCC notes in 2109), the diversity in how false religious activity has been dealt with across time and place is accounted for without contradiction in principle (even admitting that it may not have always been handled with perfect prudence and justice).
Just to add, the same principles apply to freedom of speech and publication (this is important since the disputed aspect of religious liberty is the public expression of error, which falls under the broader umbrella of speech and publication). See e.g. St. John XXIII, Pacem in Terris 12.
