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.
Primitive Catholic
While the Roman Catholic Church is not in communion with Primitive Catholic churches, Primitive Catholics are permitted under the Roman Catholic Church's 1983 Code of Canon Law to receive the sacraments of Holy Eucharist, Reconciliation, and Anointing of the Sick from Roman Catholic priests under Canon 844,3.
An ecclesiastical jurisdiction known as the Primitive Catholic Church lays claim to having spiritual and historical connections with the church of the first century and to its clergy having valid apostolic succession, but its acceptance of women clergy and the remarriage of divorcees have called the claim into question by some in the movement.
