Oh yes I know, and the Ukrainian/Ruthenian Churches would be much larger in the USA had the Latins not been so bigoted and pigheaded.  The OCA pretty much got its start  and numbers with refugees from the Slavic Eastern Catholics.   St. Luke's Byzantine Catholic Church in Sugar Creek, MO was originally a Ukie Church.  In its many years of existence it went back and forth between Catholic and Russian Orthodox 3 or 4 times.  There are old photos in the parish hall from those days.  How many other parishes did the same?
