The Error: An embracing of false ideas of religious liberty and the radical separation of Church and State (as opposed to recognizing them as two distinct spheres, the secular being informed by – but not controlled by – the religious). This contradicts the oldest teaching of the Church, Leo XIII’s “Testem Benevolentiae Nostra,” etc.
The Truth: While it is often (perhaps more often than not) prudent and beneficial to the common good to tolerate error, while no one may ever be forced to believe against his conscience, and while those in error must be treated with charity and simple kindness, error has no positive “rights” in itself. A State whose laws are not based on natural law, whose laws don’t have the Christian understanding of the True, Good, and Beautiful at their center, and whose laws don’t have the good of the souls of its citizens/subjects at their heart is bound to lead to trouble with great eternal and temporal consequences.
If one stops to think about it, it is quite obvious that there are only a few options in this regard:
1.We can have no rule of law at all.
2.We can have a rule of law based on Catholic morality.
3.We can have a rule of law based on Jewish, Muslim, Hindu, Buddhist, Wiccan, or other non-Catholic views of morality, and have our civic holidays and symbolism based on that belief system.
4.We can have a rule of law based on “secular precepts” of radical individualism and tolerance for the sake of tolerance, the effects of which:
• deny any role of religion or of the religious in the public sphere unless they deny their own precepts. This forces the religious into “schizophrenic” lives split in half between their “religious, private selves” and their “public, political selves”;
• end in abortion, “homosexual marriage,” euthanasia, divorce, rampant pornography, un-Catholic economic systems, attacks on the family via social programs (or, in a libertarian system of this sort, result in no support via acknowledgment of the rights of fathers), etc. One need not be religious to see the social effects of such policies;
• secularize historically Christian holidays and symbolism in order to appease all religions, either denying those things any civic status at all, or forcing recognition of these aspects of all religious systems equally, giving equal weight in law, for ex., to Satanism, Scientology, and Catholicism;
• sacrifice: man’s needs for culture (rooted in the word “cult”); a society’s need of a shared vision of the Good, True, and Beautiful; and a sense of historical continuity and rootedness, all in favor of ideologies which have shown themselves to be divisive and socially and psychologically unsatisfying.
That’s it. Those are the options. Which is the right choice for a Catholic? Which ends in sanity? Which builds community, a sense of place, of belonging and rootedness? Which system is more likely to be coherent and lead to happiness? Which is consistent with Catholic teaching? And, most importantly, which is most likely to lead to the salvation of souls?
