Page "Greek Old Calendarists" Paragraph 4

After a largely successful grassroots effort to resist the Greek state's new doctrine and the Gregorian calendar that originated in Western Christendom, the popularity of the Old Calendar was attacked.

The Church of Greece is the official state church and resorted to the use of state power to suppress the movement.

By the 1960s and 1970s, the ecumenical activities of a number of Orthodox leaders infused the Old Calendar Church with new followers in Greece, particularly from 1965-1972 when the monasteries of Mount Athos broke communion with the Patriarchate of Constantinople.

The Old Calendarists were relatively more successful in the United States, where religion is not regulated by the state.
