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
A 2013 modification of the norms governing personal ordinariates made it clear that membership of an ordinariate is open to those who are Catholics by baptism but have not received both of the other two sacraments of initiation, if evangelising by an ordinariate brings them back to the faith and practice of the Catholic Church. Although they lack an Anglican background, they acquire membership of an ordinariate by receiving within it some of the sacraments of initiation. Other Catholics cannot "for purely subjective motives or personal preference" be enrolled in an ordinariate. However, all Catholics may regularly attend and receive communion at ordinariate services, as they can in any Latin or Eastern Catholic parish.
