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.
Holy orders in the Catholic Church
Since 1896 many Anglican bishops have been consecrated by bishops of the Old Catholic Church. Nevertheless, all Anglican clergymen who desire to enter the Catholic Church do so as laymen and must be ordained in the Catholic Church in order to serve as priests. Catholics are, according to and Cardinal Ratzinger, obliged to hold the position that Anglican orders are invalid.
