The Catechism teaches that laity has already been deemed to have a collaborative place with Christ’s kingly, priestly, and prophetic offices within the Church, but in May Pope Benedict offered a deeper and more mature perspective of co-responsibility in a speech in Rome, with special relevancy for the work of lay apostolates such as the Lampstand Foundation.
An excerpt.
“There is still a long way to go. Too many of the baptized do not feel part of the ecclesial community and live on its margins, only coming to parishes in certain circumstances to receive religious services. Compared to the number of inhabitants in each parish, the lay people who are ready to work in the various apostolic fields, although they profess to be Catholic, are still few and far between. Of course, social and cultural difficulties abound but faithful to the Lord's mandate, we cannot resign ourselves to preserving what exists. Trusting in the grace of the Spirit which the Risen Christ guaranteed to us, we must continue on our way with renewed energy. What paths can we take? In the first place we must renew our efforts for a formation which is more attentive and focused on the vision of the Church, of which I spoke and this should be both on the part of priests as well as of religious and lay people to understand ever better what this Church is, this People of God in the Body of Christ. At the same time, it is necessary to improve pastoral structures in such a way that the co-responsibility of all the members of the People of God in their entirety is gradually promoted, with respect for vocations and for the respective roles of the consecrated and of lay people. This demands a change in mindset, particularly concerning lay people. They must no longer be viewed as "collaborators" of the clergy but truly recognized as "co-responsible", for the Church's being and action, thereby fostering the consolidation of a mature and committed laity. This common awareness of being Church of all the baptized in no way diminishes the responsibility of parish priests. It is precisely your task, dear parish priests, to nurture the spiritual and apostolic growth of those who are already committed to working hard in the parishes. They form the core of the community that will act as a leaven for the others. Although these communities are sometimes small, to prevent them from losing their identity and vigour they must be taught to listen prayerfully to the word of God through the practice of lectio divina, as the recent Synod of Bishops ardently hoped. Let us truly draw nourishment from listening, from meditating on the word of God. Our communities must not lack the knowledge that they are "Church", because Christ, the eternal Word of the Father, convokes them and makes them his People. Indeed, on the one hand faith is a profoundly personal relationship with God but on the other it possesses an essential community component and the two dimensions are inseparable. Thus young people, who are more exposed to the growing individualism of contemporary culture, the consequences of which inevitably involves the weakening of interpersonal bonds and the enfeeblement of the sense of belonging, will also taste the beauty and joy of being and feeling Church. Through faith in God we are united in the Body of Christ and all become united in the same Body. Thus, precisely by profoundly believing we may achieve communion among ourselves and emerge from the loneliness of individualism.”
