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.
Religious conversion
Membership into a Latter Day Saint church is granted only by baptism whether or not a person has been raised in the church. Latter Day Saint churches do not recognize baptisms of other faiths as valid because they believe baptisms must be performed under the church's unique authority. Thus, all who come into one of the Latter Day Saint faiths as converts are baptized, even if they have previously received baptism in another faith.
