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.
Conversion to Christianity
The Church of Jesus Christ of Latter-day Saints (LDS Church) teach that baptism is the first sacrament, called an ordinance in LDS theology, following conversion and is required for membership in the LDS Church. Baptism, according to the LDS theology, requires that the convert be accountable (credobaptism), that it be by immersion, and that it be performed by an authorized priesthood holder. As the LDS Church does not recognize the priesthood authority of other churches, all converts, even those from other Christian denominations, are required to be baptized. Following baptism, a convert is confirmed a member of the LDS Church and receives the Gift of the Holy Ghost by the laying on of hands of a Melchizedek Priesthood holder.
