On "Christifideles Laici" Benedict XVI, Full text
The Laity are "co-responsible"
Co-responsibility requires a change in mentality, particularly with regard to the role of the laity in the Church, who should be considered not as "collaborators" with the clergy, but as persons truly "co-responsible" for the being and activity of the Church. It is important, therefore, that a mature and committed laity be united, who are able to make their own specific contribution to the Church’s mission, in accordance with the ministries and tasks each one has in the life of the Church, and always in cordial communion with the bishops.
In this regard, the Dogmatic Constitution Lumen Gentium describes the nature of the relationships between laity and Pastors with the adjective "familiar": "A great many wonderful things are to be hoped for from this familiar dialogue between the laity and their spiritual leaders: in the laity a strengthened sense of personal responsibility; a renewed enthusiasm; a more ready application of their talents to the projects of their spiritual leaders. The latter, on the other hand, aided by the experience of the laity, can more clearly and more incisively come to decisions regarding both spiritual and temporal matters. In this way, the whole Church, strengthened by each one of its members, may more effectively fulfill is mission for the life of the world" (n. 37).
Dear friends, it is important to deepen and to live out this spirit of profound communion in the Church, which characterized the early Christian community, as the book of the Acts of the Apostles attests: "Now the company of those who believed were of one heart and soul" (4:32). Feel the commitment to work for the Church’s mission to be your own: through prayer, through study, through active participation in ecclesial life, through an attentive and positive gaze at the world, in the continual search for the signs of the times. Never tire of becoming more and more refined, through a serious and daily commitment to formation, through the aspects of your particular vocation as lay faithful, who are called to be courageous and credible witnesses in every sphere of society, so that the Gospel might be the light that brings hope in difficult situations, in troubles and in the darkness that men today so often find along the path of life.
