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.
Clerical celibacy
Within the Roman Catholic Church, clerical celibacy is mandated for all clergy in the Latin Church except in the permanent diaconate. Exceptions are sometimes admitted for ordination to transitional diaconate and priesthood on a case-by-case basis for married clergymen of other churches or communities who become Catholics, but ordination of married men to the episcopacy is excluded (see Personal ordinariate). Clerical marriage is not allowed and therefore, if those for whom in some particular Church celibacy is optional (such as permanent deacons in the Latin Church) wish to marry, they must do so before ordination. Eastern Catholic Churches either follow the same rules as the Latin Church or require celibacy for bishops while allowing priestly ordination of married men.
