The Faithful: hierarchy, laity, consecrated life
IV Sunday of Lent -  March 11
177. Who are the faithful?
The Christian faithful are those who, inasmuch as they have been incorporated in Christ through Baptism, have been constituted as the people of God; for this reason, since they have become sharers in Christ’s priestly, prophetic and royal office in their own manner, they are called to exercise the mission which God has entrusted to the Church. There exists a true equality among them in their dignity as children of God.
 
178. How are the people of God formed?
Among the faithful by divine institution there exist sacred ministers who have received the sacrament of Holy Orders and who form the hierarchy of the Church. The other members of the Church are called the laity. In both the hierarchy and the laity there are certain of the faithful who are consecrated in a special manner to God by the profession of the evangelical counsels: chastity or celibacy, poverty, and obedience.
 
179. Why did Christ institute an ecclesiastical hierarchy?
Christ instituted an ecclesiastical hierarchy with the mission of feeding the people of God in his name and for this purpose gave it authority. The hierarchy is formed of sacred ministers,; bishops, priests, and deacons. Thanks to the sacrament of Orders, bishops and priests act in the exercise of their ministry in the name and person of Christ the Head. Deacons minister to the people of God in the diakonia (service) of word, liturgy, and charity.
 
180. How is the collegial dimension of Church ministry carried out?
After the example of the twelve Apostles who were chosen and sent out together by Christ, the unity of the Church’s hierarchy is at the service of the communion of all the faithful. Every bishop exercises his ministry as a member of the episcopal college in communion with the Pope and shares with him in the care of the universal Church. Priests exercise their ministry in the presbyterate of the local Church in communion with their own bishop and under his direction.
 
181. Why does ecclesial ministry also have a personal character?
Ecclesial ministry also has a personal character in as much as each minister, in virtue of the sacrament of Holy Orders, is responsible before Christ who called him personally and conferred on him his mission.
 
182. What is the mission of the Pope?
The Pope, Bishop of Rome and the Successor of Saint Peter, is the perpetual, visible source and foundation of the unity of the Church. He is the vicar of Christ, the head of the College of bishops and pastor of the universal Church over which he has by divine institution full, supreme, immediate, and universal power.
 
183. What is the competence of the college of bishops?
The college of bishops in union with the Pope, and never without him, also exercises supreme and full authority over the Church.
 
184. How do the bishops carry out their mission of teaching?
Since they are authentic witnesses of the apostolic faith and are invested with the authority of Christ, the bishops in union with the Pope have the duty of proclaiming the Gospel faithfully and authoritatively to all. By means of a supernatural sense of faith, the people of God unfailingly adhere to the faith under the guidance of the living Magisterium of the Church.
 
185. When is the infallibility of the Magisterium exercised?
Infallibility is exercised when the Roman Pontiff, in virtue of his office as the Supreme Pastor of the Church, or the College of Bishops, in union with the Pope especially when joined together in an Ecumenical Council, proclaim by a definitive act a doctrine pertaining to faith or morals. Infallibility is also exercised when the Pope and Bishops in their ordinary Magisterium are in agreement in proposing a doctrine as definitive. Every one of the faithful must adhere to such teaching with the obedience of faith.
 
186. How do Bishops exercise their ministry of sanctification?
Bishops sanctify the Church by dispensing the grace of Christ by their ministry of the word and the sacraments, especially the Holy Eucharist, and also by their prayers, their example and their work.
 
187. How do the Bishops exercise their function of governing?
Every bishop, insofar as he is a member of the college of bishops, bears collegially the care for all particular Churches and for the entire Church along with all the other bishops who are united to the Pope. A bishop to whom a particular Church has been entrusted governs that Church with the authority of his own sacred power which is ordinary and immediate and exercised in the name of Christ, the Good Shepherd, in communion with the entire Church and under the guidance of the Successor of Peter.
 
188. What is the vocation of the lay faithful?
The lay faithful have as their own vocation to seek the Kingdom of God by illuminating and ordering temporal affairs according to the plan of God. They carry out in this way their call to holiness and to the apostolate, a call given to all the baptized.
 
189. How do the lay faithful participate in the priestly office of Christ?
They participate in it especially in the Eucharist by offering as a spiritual sacrifice “acceptable to God through Jesus Christ” ( 1 Peter 2:5) their own lives with all of their works, their prayers, their apostolic undertakings, their family life, their daily work and hardships borne with patience and even their consolations of spirit and body. In this way, even the laity, dedicated to Christ and consecrated by the Holy Spirit, offer to God the world itself.
 
190. How does the laity participate in the prophetic office?
They participate in it by welcoming evermore in faith the Word of Christ and proclaiming it to the world by the witness of their lives, their words, their evangelizing action, and by catechesis. This evangelizing action acquires a particular efficacy because it is accomplished in the ordinary circumstances of the world.
191. How do they participate in the kingly office?
The laity participate in the kingly function of Christ because they have received from him the power to overcome sin in themselves and in the world by self-denial and the holiness of their lives. They exercise various ministries at the service of the community and they imbue temporal activities and the institutions of society with moral values.
 
192. What is the consecrated life?
The consecrated life is a state of life recognized by the Church. It is a free response to a special call from Christ by which those consecrated give themselves completely to God and strive for the perfection of charity moved by the Holy Spirit. This consecration is characterized by the practice of the evangelical counsels.
 
193. What can the consecrated life give to the mission of the Church?
The consecrated life participates in the mission of the Church by means of a complete dedication to Christ and to one’s brothers and sisters witnessing to the hope of the heavenly Kingdom.
