Among the practical consequences and tasks regarding the mission, some require the Church's commitment to families, others regard the family itself, and others require the concerted efforts of both.

Marriage preparation, which often engages the attention of engaged person at the exterior and emotional level, should be enriched by placing a proper accent on the spiritual and ecclesial character of marriage. In pastoral preparation for marriage we have to go deeply into the aspects underlining the essential properties of marriage at the natural and supernatural levels. It is extremely useful to have the joyous participation of the Christian community which welcomes the new family, which is to be a living member of the ecclesial family. Vgl. Bisschoppensynodes, De roeping en de missie van het gezin in de Kerk en de moderne wereld, Instrumentum Laboris voor de 14e Gewone Bisschoppensynode (2015) (23 juni 2015), 73.103 Thus it is very useful for Catholic families to be involved in the preparation of engaged couples. The newlyweds can come to know a community of true friends, and from these encounters there can be born human relationships of enrichment, support, and help in difficult situations or in problems within the couple. Belonging to such a group, the faith of the couple can mature, especially if these communities of family meet regularly, read Sacred Scripture, pray together, and cultivate their faith in the light of the teaching of the Church, especially through the Catechismus-Compendium
Catechismus van de Katholieke Kerk
(15 augustus 1997). Beside all this, and as its 'fruit', there is accomplished a mutual help in daily problems which are part of the life of every family. The formation of such groups of families seems to be a sign of the times. They often arise within new communities or ecclesial movements, but are also often rooted in the parish. It seems an urgent and fascinating task to form such communities, and promote them among all the dioceses.

It will often be good to animate these groups with the presence of a priest or a pastoral worker who is well prepared. Vgl. Bisschoppensynodes, De roeping en de missie van het gezin in de Kerk en de moderne wereld, Instrumentum Laboris voor de 14e Gewone Bisschoppensynode (2015) (23 juni 2015), 75

At both the level of small communities and of parish ministry and the mass media there is needed a “... conversion of language that it might prove to be effectively meaningful”. Bisschoppensynodes, De roeping en de missie van het gezin in de Kerk en de moderne wereld, Instrumentum Laboris voor de 14e Gewone Bisschoppensynode (2015) (23 juni 2015), 77-78 This constitutes a challenge for bishops, priests, and other ministers of the Word and requires, or may require, new forms of catechesis and testimony, in full fidelity to the truth revealed by Christ. If we speak from the depths of our heart, if we never tire of being accountable to ourselves and our faith, then we can turn to others with conviction and courage. If we speak frankly to others about what we believe, we don't need to be afraid of being misunderstood, because we, too, are children of our time. While not everyone will accept what we announce, they will at least understand the proposal. This is confirmed especially by the experience of missionaries in large cities.

Beyond the joyous announcement of the Gospel, and within the context of announcing the good news of the family, it is necessary also to help those living in problematic and difficult situations to discern their living conditions in the light of the gospel. This discernment must not be content with subjective criteria, as a test for justification, but must bring together mercy with justice. The project of God in marriage and family is the way to happiness for the human being. In this work of announcing, the pastors of the Church, particularly where other worldviews or religions are present, should know such ways to conceive of and implement marriage and family to illuminate them with the light of the Gospel.
