§2 For the particular Churches entrusted to them, that office is exercised by the individual Bishops, who are the moderators of the entire ministry of the word in their Churches. Sometimes, however, in accordance with the law, a number of Bishops simultaneously carry out that office together in respect of a number of different Churches.
Can. 757 It belongs to priests, as cooperators of the Bishops, to proclaim the Gospel of God. For the people entrusted to their care, this task rests especially on parish priests, and on other priests entrusted with the care of souls. Deacons also are to serve the people of God in the ministry of the word, in union with the Bishop and his presbyterium.
Can. 758 By reason of their consecration to God, members of institutes of consecrated life bear particular witness to the Gospel, and so are fittingly called upon by the Bishop to help in proclaiming the Gospel.
Can. 759 The lay members of Christ’s faithful, by reason of their baptism and confirmation, are witnesses to the good news of the Gospel, by their words and by the example of their Christian life. They can also be called upon to cooperate with Bishops and priests in the exercise of the ministry of the word.
Can. 760 The mystery of Christ is to be faithfully and fully presented in the ministry of the word, which must be founded upon sacred Scripture, Tradition, liturgy and the Magisterium and life of the Church.
Can. 761 While pride of place must always be given to preaching and catechetical instruction, all the available means of proclaiming Christian doctrine are to be used: the exposition of doctrine in schools, in institutes of higher learning, at conferences and meetings of all kinds; public declarations by lawful authority on the occasion of certain events; the printed word and other means of social communication.
CHAPTER I : PREACHING THE WORD OF GOD
Can. 762 The people of God are first united through the word of the living God, and are fully entitled to seek this word from their priests. For this reason sacred ministers are to consider the office of preaching as of great importance, since proclaiming the Gospel of God to all is among their principal duties.
Can. 763 Bishops have the right to preach the word of God everywhere, even in churches and oratories of religious institutes of pontifical right, unless the local Bishop has expressly forbidden it in particular cases.
Can. 764 Without prejudice to the provisions of can. 765, priests and deacons, with the at least presumed consent of the rector of a church, have the faculty to preach everywhere, unless this faculty has been restricted or removed by the competent Ordinary, or unless particular law requires express permission.
Can. 766 The laity may be allowed to preach in a church or oratory if in certain circumstances it is necessary, or in particular cases it would be advantageous, according to the provisions of the Episcopal Conference and without prejudice to can. 767 §1.
Can. 767 §1 The most important form of preaching is the homily, which is part of the liturgy, and is reserved to a priest or deacon. In the course of the liturgical year, the mysteries of faith and the rules of Christian living are to be expounded in the homily from the sacred text.
§3 It is strongly recommended that, if a sufficient number of people are present, there be a homily at weekday Masses also, especially during Advent and Lent, or on a feast day or an occasion of grief.
Can. 768 §1 Those who announce the word of God to Christ’s faithful are first and foremost to set out those things which it is necessary to believe and to practice for the glory of God and the salvation of all.
§2 They are also to explain to the faithful the teaching of the Magisterium of the Church concerning the dignity and freedom of the human person; the unity, stability and duties of the family; people’s social obligations and the ordering of temporal affairs according to the plan established by God.
Can. 770 At certain times, according to the regulations of the diocesan Bishop, parish priests are to arrange for sermons in the form of retreats and missions, as they are called, or in other forms adapted to requirements.
Can. 771 §1 Pastors of souls, especially Bishops and parish priests, are to be solicitous that the word of God is preached to those also of the faithful who, because of the circumstances of their lives, cannot sufficiently avail themselves of the ordinary pastoral care or are even totally deprived of it.
§2 They are also to take care that the good news of the Gospel reaches those living in their territory who are nonbelievers, since these too, no less than the faithful, must be included in the care of souls.
CHAPTER II : CATECHETICAL FORMATION
Can. 773 It is pastors of souls especially who have the serious duty of attending to the catechesis of the christian people, so that, through doctrinal formation and the experience of the christian life, the living faith of the people may be manifest and active.
Can. 775 §1 While observing provisions made by the Apostolic See it is the responsibility of diocesan Bishops to issue norms concerning catechetical matters; to ensure that appropriate means of catechesis are available, even by preparing a catechism, if this seems opportune; to foster and to coordinate catechetical initiatives.
Can. 776 By virtue of his office, the parish priest is bound to ensure the catechetical formation of adults, young people and children. To this end, he is to avail himself of the help of clerics attached to the parish, as well as of members of institutes of consecrated life and of societies of apostolic life, being mindful of the character of each institute; and the assistance of lay members of Christ’s faithful, especially catechists. All of these, unless they are lawfully impeded, are not to refuse to give their labours willingly. The parish priest is also to promote and to foster the role of parents in the family catechesis mentioned in can. 774, §2.
5° the faith of young people and of adults is strengthened, enlightened and developed by various catechetical methods and initiatives .
Can. 778 Religious Superiors and Superiors of societies of apostolic life are to ensure that catechetical formation is diligently given in their churches and schools, and in other works in any way entrusted to their care.
Can. 779 Catechetical formation is to be given by employing all those aids, educational resources and means of communication which seem the more effective in securing that the faithful, according to their character capability, age and circumstances of life, may be more fully steeped in catholic teaching and prepared to put it into practice.
Can. 780 Local Ordinaries are to ensure that catechists are duly trained to carry out their office properly, namely, that continuing formation is available to them, that they have an appropriate knowledge of the teaching of the Church, and that they learn both the theory and the practice of the principles of pedagogy.
