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.
Legion of Mary
Membership is open to all baptised Catholics. After visiting a Praesidium a few times, one can join the legion as a probationary member for three months. Then, a decision is made on whether to join the legion as an active member permanently. During the probationary period, probationary members learn about the legion system by reading the "Handbook of the Legion of Mary" and its active works by listening to reports of active works undertaken by fellow legionaries. At the end of probationary period, members say an oath of "Legion promise", a pledge of allegiance to the Holy Spirit and to Mary, and become apermanent active members.
