At heart, it seems to me that Roman Catholicism monarchist. If it is, why would it be expected to promote, rather than adapt to, a society of individualistic thought and entrepreneurship, which at their base are by definition anti-authoritarian?
The United States isn't catholic or protestant. It is Judeo-Christian.
Attempts to make it other than that almost always go awry, as we are founded on what a man believes is his own business; not his neighbors, and especially not his government's.
