What is the Future of "Integralism"

A Catholic author provided a good overview of what is being attempted today. To put this in lay language, I may miss the mark to some degree, Integralism is a.) for a Pope to order what the government should do and b.) that is a good thing.

While the link goes deep into scholarly writing about Catholic theology surrounding Integralism we can skip this and go to simple examples. These examples are the many monarchs who took on Popes as collaborators and Popes who did the same with civic rulers. They used each other.

The link points out that arrangement sometimes worked to the benefit of the average citizen. The Pope was an independent actor as was the king. When either of them was tempted to go off the deep end it was sometimes in the interests of the other to push back.  

This model of integralism was established in the Middle Ages when communication and travel was slow and costly. Thus, out in the countryside were both representatives of the King and the Pope. Policies and practices were not consistent across the region because these distant reps worked out their own power sharing deals and the degree to which they conformed or did not conform to the home office. This situation allowed for an ebb and flow in conditions and cultural change.

Today, Catholic leadership wants its religious views on gay marriage and anti-abortion to be nationalized. The courtship between politicians and clergy leadership does the same dance it did back in the middle ages. Back then an edict like no abortions or gay marriage could not be enforced uniformly because of costly travel. Edits could be issued but safety valves allowed noncompliance.

Today we see gay marriage approved across the country. Deals between Bishops and politicians to all but ban abortions are being circumvented. The edicts in some states are failing because women get abortions in other ways. There is speculation that the nation-wide number of abortions, which had started to rise just before the overrule of Roe, may be rising as we speak. I read this in an anti-abortion article. 

Integralism found its way into Catholic writing back in the Middle Ages. It should be abandoned, and the church should stay in its own lane.
