Canonically, each Eastern Catholic Church is "" or autonomous with respect to other Catholic churches, whether Latin or Eastern, though all accept the spiritual and juridical supreme authority of the pope. Thus a Maronite Catholic is normally directly subject only to a Maronite bishop. However, if members of a particular church are so few that no hierarchy of their own has been established, their spiritual care is entrusted to a bishop of another ritual church. For instance, members of the Latin Church in Eritrea are under the care of the Eastern rite Eritrean Catholic Church, whereas the other way around may be the case in other parts of the world.
