Particularly in view of the fact that they will become the domestic church and "Sanctuary of life" (EV 92-92), they will become part in a new way of the "people of life and for life" (EV 6, 101). The contraceptive mentality which is prevalent today in so many places, and the widespread, permissive laws with all they imply in terms of contempt for life from the moment of conception to death, constitute a series of multiple attacks to which the family is exposed and wounded in the most intimate part of its mission, and which impede its development according to the requirements of authentic human growth (cf. Centesimus Annus, 39). Therefore, today more than before, formation is needed of the minds and hearts of the members of new families not to conform to the prevailing mentality. In this way, through their own new family life, one day they will be able to contribute towards creating and developing the culture of life by respecting and welcoming new lives in their love, as the testimony and expression of the proclamation, celebration and service to every life (cf. EV 83-84, 86, 93).
