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.
Secular Order of Discalced Carmelites
Depending on their existing provincial statutes and with the approval of their local council, their communities accept Catholics in good standing in the Church who meet the age requirement into formation. Admission into formation depends on a clear indication of a Carmelite vocation and maturity in faith in the opinion of the local council of the community petitioned, and permission to profess the Promise of the Seculars requires a number of years spent in spiritual formation and the study of contemplative prayer under the direction of the community's formators. Catholics begin by discovering a community of Seculars which they visit for monthly meetings and may eventually join. Communities are listed in online provincial directories (see bibliography below).
