‘Coming to the second element of a religious and priestly vocation, we learn from the Roman Catechism that those have a divine vocation who are called by the legitimate ministers of the Church. This in no way contradicts what we have said about the divine call; rather it is very closely connected with it. For the divine calling of a man to the religious and priestly state destines him to a life in public of holiness and to the exercise of a hierarchic ministry, in the visible, hierarchic society of the Church; consequently such calling ought to have also the confirmation, admission and guidance of those hierarchic rulers to whose administration the Church has been committed by God.’
In these words the Holy Father makes it clear that there would be a kind of contradiction in a vocation to the religious life of priesthood that came simply from God and did not have besides the approval of the Church, that is, of responsible ecclesiastical superiors.
