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.
Society of Catholic Priests
In the SCP NA, membership is open to all Anglican clergy who a) believe that the churches of the Anglican Communion are part of the one holy and catholic and apostolic church; b) are members of The Episcopal Church or the Anglican Church of Canada; c) embrace as colleagues all those admitted to holy orders in the same; d) believe in the real presence of Christ in the Eucharist; e) embrace the sacramental life of the Church as means of God's grace; f) and keep the rule of life of the society. In the SCP NA, professed but unordained members of religious communities may also be admitted as full members. Seminarians and seminary graduates preparing for ordination may be admitted as "provisional members", becoming full members automatically upon their diaconal ordination.
