Many societies fell apart that were theocracies. The Holy Roman Empire was one of them.As for morality, having a state aligned with a church is no guarantee that immorality will be absent.
Oh, certainly not. Sin will always be a problem, whether or not a state accepts its obligation to cooperate with the Church and help build a Christian civilization.
However, the devil is in the details here, and despite the sinfulness of humans who lived during the days of the Holy Roman Empire (or in other Christian states), it cannot even be argued that common culture was orders of magnitude more moral and decent than today’s secularized societies. The past shows us what happens when honest people (those who govern as well as those who are governed) place the Lord first in their lives and the rich, beautiful, innately noble cultures that arise as a result.
The point is that we can do better than what we have now, and we have before, so persisting in failure will never bring success.
History has also shown us that the religious institutions are also susceptible to the allure of sharing power with the temporal state. This has even been the case with our church.
Power-sharing is not the problem; the Church needs to have a voice and leverage in how civil officials govern, or else the Church will not be heeded and her moral guidance ignored. Western civilization was never perfect, of course, but it was infinitely better when the Church could rein in secular profligates with the tools of excommunication, interdict, and the last resort of papal absolution of oaths of allegiance.
They’re a little pricey, but Warren H. Carroll’s second and third volumes of his
History of Christendom series are very well worth the read on this matter. He does a much better job of explaining the details and the facts of good Catholic government better than I ever could; I’d have to plagiarize the man otherwise.
It is better to be in opposition to the government than to be in bed with it.
Certainly, which is what I’m getting at with all my bluster.
Don’t misunderstand me; I am not at all suggesting the state should have any power over the Church. To be in bed with the state would mean to suggest that the civil authority is an authority unto itself that needs no guidance or control. I am suggesting, instead, that Catholic teaching be applied to government and enforced by the Church, following the models of old. The government is the servant of the people, not the master of them, but a government without proper Christian moral authority at its head as both a matter of law and of custom will eventually turn reckless and govern exclusively for its own ends, with Christian teaching marginalized and later, wholly done away with - as is the case with American society.
In all our modern attempts to rein in government and define its limits and its scope, where we have failed is in removing its Christian limitation. Separation of church and state was the worst idea modern politics has had.
