The Ukrainian Catholic Church in the United States has limited growth opportunities, because in the United States and in other non-Ukrainian jurisdictions, it is primarily a church for immigrants from Ukraine and their children (during the time the children are subject to parental control). It maintains this characteristic by resisting the use of English in its liturgies and, in some parishes, insisting on the use of the Julian Calendar to calculate dates of Christmas, Easter, and other religious holidays, thus placing themselves outside the U.S. mainstream. The Ukrainian Catholic Church considers the descendants of those who migrated from Ukraine to be part of a “diaspora,” not recognizing that many in the so-called “diaspora” have lived in the United States for generations and do not necessarily desire to return to Ukraine.
