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.
Open communion
The Catholic Church does not practise or recognise open communion. In general it permits access to its Eucharistic communion only to baptized Catholics. In lieu of Holy Communion, some parishes invite non-Catholics to come forward in the line, with their arms crossed over their chest, and receive a blessing from the priest. However, Canon 844 of the 1983 Code of Canon Law of the Latin Church and the parallel canon 671 of the Code of Canons of the Eastern Churches also recognizes that in certain circumstances, by way of exception, and under certain conditions, access to these sacraments may be permitted, or even commended, for Christians of other Churches and ecclesial Communities.
