Thanks for the term. I didn't know the Catholic Church regarded this concept as applicable doctrine. What did the Priest reply to you?
The Priest was clueless.
He admitted that Subsidiarity was still doctrine, yet he did not understand how his support for outright socialism, and his advocacy of “social justice” was not in keeping with the doctrine of Subsidiarity.
I later mailed him a bunch of Catholic literature in support of my view that it is “impossible to be, at the same time, a true Catholic and a Socialist”
