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.
Ecumenical Catholic Church
The Ecumenical Catholic Church (ECC) is a denomination within the universal Christian Church. It teaches the faith of the Nicene Creed, that one God exists in three coequal and coeternal persons—the Father, Son, and Holy Spirit—and that Jesus is the Son of God and redeemer of humanity, uniting Christians through the rebirth of Baptism and the fellowship of the Eucharist. The liturgy of the ECC is similar to that of the Roman Catholic Church, but it is politically independent and not under the jurisdiction of the Vatican or the Roman hierarchy and thus is one of the "Independent Catholic Churches". While the ECC shares the core Christian beliefs with the Roman Church and most Protestant and Orthodox denominations, it is more liberal on many social issues.
