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.
Catholic theology
Catholics believe that the Catholic Church is the continuing presence of Jesus on earth. Jesus told his disciples "Abide in me, and I in you. … I am the vine, you are the branches". Thus, for Catholics, the term "Church" refers not merely to a building or exclusively to the ecclesiastical hierarchy, but first and foremost to the people of God who abide in Jesus and form the different parts of his spiritual body, which together composes the worldwide Christian community.
