You have a strange theology of Church, Hermenegild. Why talk of churches? Are you a protestant? The Church is ONE, holy, CATHOLIC (universal), apostolic.
So what is this "All particular Churches / Just the Roman Church?" of which you speak?
Our Lady at La Salette spoke of the Church being in eclipse, the world being in dismay. It's a simple enough concept. We can observe this for ourselves 171 years later.
