Apologies- sincerely, am having difficulty parsing out what you mean. Drawing from current events, are you speaking about a collapse of the Church's status in society, such as public subsidies and government grants, the loss of assets and so forth?

Or is this about foreign conquest? An autocratic anti-Catholic regime?

In all of these cases, I agree that the answer for each individual is to keep the faith,  embrace the cross. Plenty of regimes have collapsed throughout history, and the faithful have responded in all kinds of ways.

The responsibility of Church leadership prior to the collapse is to try to prevent it from happening. Afterwards, the responsibility of each person is to hold fast to the faith.

But maybe my morning brain is totally missing your point.
