Other Pastoral Ministries include:
How does a priest carry out his proper ministry?
A priest, although ordained for a universal mission, exercises his ministry in a particular Church. This ministry is pursued in sacramental brotherhood with other priests who form the “presbyterate”. In communion with the bishop, and depending upon him, they bear responsibility for the particular Church.
With what authority is the priestly ministry exercised?
Ordained priests in the exercise of their sacred ministry speak and act not on their own authority, nor even by mandate or delegation of the community, but rather in the Person of Christ the Head and in the name of the Church. Therefore, the ministerial priesthood differs essentially and not just in degree from the priesthood common to all the faithful for whose service Christ instituted it.
