2. The Ministries of the Lay Christian Faithful in the Celebration of Holy Mass
[43.] For the good of the community and of the whole Church of God, some of the lay faithful according to tradition have rightly and laudably exercised ministries in the celebration of the Sacred Liturgy. It is appropriate that a number of persons distribute among themselves and exercise various ministries or different parts of the same ministry.
[44.] Apart from the duly instituted ministries of acolyte and lector, the most important of these ministries are those of acolyte and lector by temporary deputation. In addition to these are the other functions that are described in the Roman Missal, as well as the functions of preparing the hosts, washing the liturgical linens, and the like. All, “whether ordained ministers or lay faithful, in exercising their own office or ministry should do exclusively and fully that which pertains to them”. In the liturgical celebration itself as well as in its preparation, they should do what is necessary so that the Church’s Liturgy will be carried out worthily and appropriately.
[45.] To be avoided is the danger of obscuring the complementary relationship between the action of clerics and that of laypersons, in such a way that the ministry of laypersons undergoes what might be called a certain “clericalization”, while the sacred ministers inappropriately assume those things that are proper to the life and activity of the lay faithful.
[46.] The lay Christian faithful called to give assistance at liturgical celebrations should be well instructed and must be those whose Christian life, morals and fidelity to the Church’s Magisterium recommend them. It is fitting that such a one should have received a liturgical formation in accordance with his or her age, condition, state of life, and religious culture. No one should be selected whose designation could cause consternation for the faithful.
[47.] It is altogether laudable to maintain the noble custom by which boys or youths, customarily termed servers, provide service of the altar after the manner of acolytes, and receive catechesis regarding their function in accordance with their power of comprehension. Nor should it be forgotten that a great number of sacred ministers over the course of the centuries have come from among boys such as these. Associations for them, including also the participation and assistance of their parents, should be established or promoted, and in such a way greater pastoral care will be provided for the ministers. Whenever such associations are international in nature, it pertains to the competence of the Congregation for Divine Worship and the Discipline of the Sacraments to establish them or to approve and revise their statutes. Girls or women may also be admitted to this service of the altar, at the discretion of the diocesan Bishop and in observance of the established norms.
