Walking with lay people to foster their vocation and mission in the world and the Church


Lay people comprise over 99.9% of the “People of God” as the Council characterised the Church in Lumen Gentium. In turn, perhaps 90% or more of the lives of lay people is spent at work, raising families, contributing to communities or otherwise building up the Kingdom of God..Hence, the importance of what Joseph Cardijn often characterised as the “lay apostolate of lay people” carrying out their mission building up and transforming their lives, communities and the world. And the added importance of those movements, communities and organisations that promote this lay apostolate.

The lay apostolate

Cardijn’s vision corresponds closely with that ultimately incorporated in Lumen Gentium, §31:

[T]he laity, by their very vocation, seek the kingdom of God by engaging in temporal affairs and by ordering them according to the plan of God. They live in the world, that is, in each and in all of the secular professions and occupations. They live in the ordinary circumstances of family and social life… They are called there by God that by exercising their proper function and led by the spirit of the Gospel they may work for the sanctification of the world from within as a leaven. In this way they may make Christ known to others, especially by the testimony of a life resplendent in faith, hope and charity… 

This vision is further developed in Gaudium et Spes §43, which adds:

Secular duties and activities belong properly although not exclusively to laypeople. Therefore acting as citizens in the world… Laypeople should also know that it is generally the function of their well-formed Christian conscience to see that the divine law is inscribed in the life of the earthly city… [E]nlightened by Christian wisdom and giving close attention to the teaching authority of the Church, let the layperson take on his/her own distinctive role.

In turn, Apostolicam Actuositatem reiterates this understanding and emphasises the need for formation for this lay apostolate, praising the work of those movements, communities and organisations devoted to its promotion. Indeed, §26 of the decree insists on the need to incorporate the work of these movements, communities and organisations into the Church’s work through councils established at diocesan, national and global  level. In particular, it calls for “a special secretariat” to be established “at the Holy See for the service and promotion of the lay apostolate” in which “the various movements… of the apostolate of the laity throughout the world should also be represented.”


Paradoxically, despite this clear endorsement of the lay apostolate by the Council Fathers, the concept of “lay apostolate” has largely disappeared from Church vocabulary, particularly in English, where it has been displaced by a growing emphasis on “ministry,” including “lay ministry.” And yet it is clear that “ministry” in the Vatican II documents relates principally to the ordained ministry. In another paradox, despite the impressive growth in the number of lay theologians around the world, the study of the lay apostolate by theologians appears to have barely progressed since the Council.

Even more concerning is the equally paradoxical decline since the Council of many movements devoted to the lay apostolate. Instead, we have witnessed the rise of many more overtly “spiritual” movements that sometimes appear to lack the social dimension of the lay apostolate movements. We particularly note that the provisions of Apostolicam Actuositatem §26 remain largely unimplemented, particularly in relation to the establishment of participative structures for lay movements. Even the Dicastory for Laity, Family and Life established in 2016 fails to provide for this.

In this context, we note the dissolution of the Conference of International Catholic Organisations in 2008, a conference that brought together many of the international movements and organisations most responsible for the promotion of the lay apostolate. As a result, there is no longer any body that represents or advocates on behalf of lay organisations before the universal Church. The consequences of this, we believe, are particularly visible in the lack of participation by international lay movements in the First Assembly of the Synod on Synodality.


Theologians often speak of the “reception” or “non-reception” of a particular teaching of the Church or a Council. Here, we regretfully observe that the Vatican II teaching on lay apostolate and the role of the lay movements appears not to have been received to the extent that the Council Fathers – and the lay auditors who assisted in the drafting of the Council documents – would have envisaged and desired. While the post-conciliar understanding of “lay ministry” is undoubtedly a positive development, we are nevertheless greatly concerned that it appears to have obscured and overshadowed the Church’s understanding of “the lay apostolate” “proper” to lay people. 

We lament the decline of the lay apostolate movements and we express our concern at the lack of a successor organisation to the ICO Conference. We believe that there is an urgent need for a renewed attention to and reception of the teachings of the Council on lay apostolate.

We note that the Instrumentum Laboris for the First Assembly raises many questions relating to lay movements, organisations and communities. We believe that it is contrary to the notion of synodality understood as “walking together” that these questions should be addressed in the absence of so many lay movements.


We call on participants at the Synod on Synodality to reflect deeply on the above developments. We express the hope that changes will be made to ensure much broader representation of the international lay movements, communities and organisations at the Second Assembly of the Synod.

We call on the Synod participants, particularly its lay participants, to speak out strongly on the above issues and ensure that measures are proposed to meet these challenges, including particularly the promotion of the lay apostolate and the development of structures representing lay people, their movements and communities at every level of the Church…

Let us together build a Church that walks together with ordinary people in the struggles of their daily lives at work, in their families and in the community.
