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.
Catholicisation
In 1439 in Florence, the Declaration of Union was adopted, according to which "the Roman Church firmly believes that nobody, who does not belong to the Catholic Church, not only unbelievers, but Judeans (Jews), nor heretics, nor schismatics, cannot enter the kingdom of heaven, but all will go to the eternal fire, which is saved for devils and their angels, if they not before death turn to that church". The Council of Trent (1545–63) had the mission to gain, apart from "stray" Protestants, also the numerous "schismatics" in southeastern Europe.
