The difficulty of giving catechesis to children living in families who do not practice their religion at all or do so in an entirely inadequate way is becoming more and more marked. Sometimes questions are raised about the very possibility and appropriateness of giving them a catechesis. Catechesis is certainly not to be omitted for such children; rather, it is to be planned and carried out in a way that fits in with actual circumstances and conditions. In these cases there is need to establish contact with the families and to study their mental attitudes and styles of life, SO that some means can be found to open a dialogue with them. It is also necessary that catechesis present its material in a way that really responds to the concrete possibilities of these children.
