The Church has been occupied by Modernists for awhile now. Were you not aware of that?
You seem to be equating being "occupied by Modernists" -- i.e., some of the members of the Roman Catholic Church are as-yet-undisciplined Modernists as individuals -- with the demonstrable fact that the entire entity formerly known as the Roman Catholic Church is now and has been for more than five decades unabashedly Modernist in Her clearly-altered doctrine, worship and discipline. These two situations are not even remotely equivalent.
