In Latin, the word minister means “service,” and in a way, all Catholics participate in the ministry of the Church. However, ordained ministry still has authority over the faithful laity. The pope rules over the hierarchy of the Church. Ordained bishops and priests serve in dioceses and parishes; their responsibilities include administering the sacraments. Members of religious orders who take vows of poverty, chastity, and obedience, also fulfill special aspects of the Church's ministry.
