The parents’ ministry of evangelization and catechesis ought to play a part in their children’s lives also during adolescence and youth, when the children, as often happens, challenge or even reject the Christian faith received in earlier years. Just as in the church the work of evangelization can never be separated from the sufferings of the apostle, so in the Christian family parents must face with courage and great interior security the difficulties that their ministry of evangelization sometimes encounters in their own children.
