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.
Personal ordinariate
Ordinariate membership as an entry to full communion with the Catholic Church is not limited solely to members of churches in the Anglican Communion. The founding document of personal ordinariates stated that their members would either be people "originally belonging to the Anglican Communion and now in full communion with the Catholic Church" (former Anglicans) or those "who receive the Sacraments of Initiation within the jurisdiction of the Ordinariate". (The sacraments of initiation are baptism, confirmation, and eucharist.) Moreover, the personal ordinariates have extended the meaning of the word "Anglican" in this context to include members of any "Protestant Church linked to the Church of England, such as the Lutheran or Methodist Church" in Great Britain or to anyone who has ever been an "Anglican, Episcopalian, Methodist, or AME" in the United States. Therefore, many individuals who have never formally been part of a church in the Anglican Communion may become Catholic through an ordinariate, just as they might through any diocesan parish.
