In Roman Catholicism, the term national church can refer to the church claiming pastoral oversight over a specific country (for which concept see national church), but more often to either a parish catering to immigrants from another nation, or to a church building in Rome dedicated to a specific country. Such national churches may hold church services and other activities in that nation's language, and/or following that nation's liturgies, which may be slightly different from the liturgy approved by the local episcopal conference.
