Personal ordinariate
If membership by reception of the sacraments of initiation within an ordinariate is open not only to the Catholics mentioned in the 2013 amendment but to others also who have no Anglican background - something on which no express statement has been issued - anyone who has not yet received all three sacraments of initiation may join. This includes non-Christians, those who, in the view of the Catholic Church, do not have valid baptism (such as Mormons), and those who, again in the view of the Catholic Church, have valid baptism but not valid confirmation or Eucharist. Protestants in general are seen as lacking valid confirmation, but the Eastern churches and some Western ones, such as some Old Catholic churches and the Polish National Catholic Church, are recognized as having valid sacraments.
Catholic Church in the United States
By far, most Catholics in the United States belong to the Latin Church and the Roman Rite of the Catholic Church. Rite generally refers to the form of worship ("liturgical rite") in a church community owing to cultural and historical differences as well as differences in practice. However, the Vatican II document, "Orientalium Ecclesiarum" ("Of the Eastern Churches"), acknowledges that these Eastern Catholic communities are "true Churches" and not just rites within the Catholic Church. There are 14 other Churches in the United States (23 within the global Catholic Church) which are in communion with Rome, fully recognized and valid in the eyes of the Catholic Church. They have their own bishops and eparchies. The largest of these communities in the U.S. is the Chaldean Catholic Church. Most of these Churches are of Eastern European and Middle Eastern origin. Eastern Catholic Churches are distinguished from Eastern Orthodox, identifiable by their usage of the term Catholic.
