Just a note of historical context - Cardinal O'Malley, is a member of the Order of Friars Minor Capuchin. Throughout the history of the unfortunate estrangement between East and West, the various branches of the Franciscan orders have always been much more conciliatory with the East, that, for example, the Dominicans. While this is a generalization, it is supported when you look at the historical evidence that Father Christiaan Kappes has revealed in his various articles and books.
At our little Ruthenian Catholic Church in Olean, New York, the reason that the parish did not go Orthodox at Toth's urging was the intercession of the Franciscan Friars at St. Bonaventure University under Father Joe Butler. Later in the 1930s, when the second schism took place, Father Tom Plassman personally visited the parish and listened to grievances. They were addressed fairly and justly.
