<P> Similarly the Catholic Faith Handbook for Youth states that "...not all Catholics are Roman Catholics and there are other Catholic Churches," using the term "Roman Catholic" to refer to Western Church members alone . The same distinction is made by some writers belonging to Eastern Catholic Churches . That this view is not the only one, not alone at the level of the Holy See and in reference books such as John Hardon's Modern Catholic Dictionary, but also at a popular level, is shown by the use of terms such as "Byzantine Roman Catholic" and "Maronite Roman Catholic" as self - identification by individuals or as the name of a church building .
