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
Depending on which of these denominations one enters, the sacrament of Confirmation, also known as Chrismation by eastern Christians, may be immediately administered after the baptism. In the Latin Catholic Church, infants who are baptized are not confirmed, but instead must wait until they're in their teens to be confirmed. In the Eastern Orthodox Church, and many Eastern Catholic Churches, infants are Chrismated and communed by a priest or bishop immediately after they are baptized. When an adult convert enters the Catholic or Orthodox Church, they are immediately confirmed after baptism, upon which, a clergy member will anoint the forehead with olive oil (or in the case of Byzantine Christians, the forehead, eyes, nostrils, mouth, ears, breast, hands, and feet), calling upon the Holy Spirit to seal the convert with his gifts. After confirmation ensues, the convert is invited to partake of first communion. These rites usually occur on Easter Vigil.
