Here is what Bishop Jenky actually stated. Note that he shows the example of four different enemies of the Church in the past 150 years, not only Hitler or Stalin.
"Remember that in past history other governments have tried to force Christians to huddle and hide only within the confines of their churches like the first disciples locked up in the Upper Room.
In the late 19th century, Bismarck waged his “Kulturkampf,” a Culture War, against the Roman Catholic Church, closing down every Catholic school and hospital, convent and monastery in Imperial Germany.
Clemenceau, nicknamed “the priest eater,” tried the same thing in France in the first decade of the 20th Century.
Hitler and Stalin, at their better moments, would just barely tolerate some churches remaining open, but would not tolerate any competition with the state in education, social services, and health care.
In clear violation of our First Amendment rights, Barack Obama – with his radical, pro abortion and extreme secularist agenda, now seems intent on following a similar path."
