From Pope St. John Paul II’s Apostolic Exhortation Familiaris Consortio (1981):
Still within the Church, which is the subject responsible for the pastoral care of the family, mention should be made of the various groupings of members of the faithful in which the mystery of Christ’s Church is in some measure manifested and lived. One should therefore recognize and make good use of—each one in relationship to its own characteristics, purposes effectiveness and methods—the different ecclesial communities, the various groups and the numerous movements engaged in various ways, for different reasons and at different levels, in the pastoral care of the family.
For this reason the Synod expressly recognized the useful contribution made by such associations of spirituality, formation and apostolate. It will be their task to foster among the faithful a lively sense of solidarity, to favor a manner of living inspired by the Gospel and by the faith of the Church, to form consciences according to Christian values and not according to the standards of public opinion; to stimulate people to perform works of charity for one another and for others with a spirit of openness which will make Christian families into a true source of light and a wholesome leaven for other families.
It is similarly desirable that, with a lively sense of the common good, Christian families should become actively engaged, at every level, in other non-ecclesial associations as well. Some of these associations work for the preservation, transmission and protection of the wholesome ethical and cultural values of each people, the development of the human person, the medical, juridical and social protection of mothers and young children, the just advancement of women and the struggle against all that is detrimental to their dignity, the increase of mutual solidarity, knowledge of the problems connected with the responsible regulation of fertility in accordance with natural methods that are in conformity with human dignity and the teaching of the Church. Other associations work for the building of a more just and human world; for the promotion of just laws favoring the right social order with full respect for the dignity and every legitimate freedom of the individual and the family, on both the national and international level; for collaboration with the school and with the other institutions that complete the education of children, and so forth.
