From Pope St. John Paul II’s Apostolic Exhortation Familiaris Consortio (1981):
Since God’s plan for marriage and the family touches men and women in the concreteness of their daily existence in specific social and cultural situations, the Church ought to apply herself to understanding the situations within which marriage and the family are lived today, in order to fulfill her task of serving.8
This understanding is, therefore, an inescapable requirement of the work of evangelization. It is, in fact, to the families of our times that the Church must bring the unchangeable and ever new Gospel of Jesus Christ, just as it is the families involved in the present conditions of the world that are called to accept and to live the plan of God that pertains to them. Moreover, the call and demands of the Spirit resound in the very events of history, and so the Church can also be guided to a more profound understanding of the inexhaustible mystery of marriage and the family by the circumstances, the questions and the anxieties and hopes of the young people, married couples and parents of today.9
To this ought to be added a further reflection of particular importance at the present time. Not infrequently ideas and solutions which are very appealing but which obscure in varying degrees the truth and the dignity of the human person, are offered to the men and women of today, in their sincere and deep search for a response to the important daily problems that affect their married and family life. These views are often supported by the powerful and pervasive organization of the means of social communication, which subtly endanger freedom and the capacity for objective judgment.
Many are already aware of this danger to the human person and are working for the truth. The Church, with her evangelical discernment, joins with them, offering her own service to the truth, to freedom and to the dignity of every man and every woman.
