By the time the immigrants’ children, and especially the immigrants’ grandchildren, grow up, they have learned English in school, know little to no Ukrainian, and are otherwise fully assimilated into U.S. culture. To the extent that the children maintain any religious affiliation, they are either Roman Catholic or join some non-Catholic denomination. To the extent that a Ukrainian Catholic Church in the United States is able to make progress toward adaptation (e.g. the use of English in its liturgies and in the conducting of parish business), the next group of immigrants arrives from the old country and insists that the church maintain its old world characteristics without change and all former progress is reversed.
