In order for this vision of the domestic Church to exist, we must form parents.
204. Within the parish boundaries, the Christian family is the ﬁrst and most basic ecclesial community. That is where the fundamental values of Christian life are lived and passed on. It is called “domestic church.”(Lumen Gentium 11) In it the parents are the primary transmitters of the faith to their children, teaching them through example and word to be true missionary disciples.
Pope John Paul envisioned the Christian family as a seed in the world, relating to others not first and not exclusively through religious stuff, but in the concerns of ordinary life:
Likewise, when this experience of missionary discipleship is authentic, “a family becomes the evangelizer of many other families, and of the neighborhood of which it forms part.”(Familiaris Consortio 52) This operates in daily life, “in and through the events, problems, difficulties and circumstances of everyday life.”(Familiaris Consortio 51)
The operative verb for family formators is “equip.” If people can be formed in effective outreach, then this vision of family might have a chance of realization:
The Spirit who makes everything new, acts even within abnormal situations in which a process of transmission of faith takes place, but we must recognize that under current circumstances, this process sometimes faces considerable difficulties. The parish intends to reach not only isolated individuals, but the life of all families, to enhance their missionary dimension.
