On December 8, Pope Benedict XVI released his message for the World Day of Peace (January 1, 2013). While the bulk of the message is about life, economic concerns, and freedom, Pope Benedict also discussed the role of marriage and the family in promoting a “culture of peace.”
Pope Benedict XVI: There is also a need to acknowledge and promote the natural structure of marriage as the union of a man and a woman in the face of attempts to make it juridically equivalent to radically different types of union; such attempts actually harm and help to destabilize marriage, obscuring its specific nature and its indispensable role in society.
These principles are not truths of faith, nor are they simply a corollary of the right to religious freedom. They are inscribed in human nature itself, accessible to reason and thus common to all humanity. The Church’s efforts to promote them are not therefore confessional in character, but addressed to all people, whatever their religious affiliation. Efforts of this kind are all the more necessary the more these principles are denied or misunderstood, since this constitutes an offence against the truth of the human person, with serious harm to justice and peace.
No one should ignore or underestimate the decisive role of the family, which is the basic cell of society from the demographic, ethical, pedagogical, economic and political standpoints. The family has a natural vocation to promote life: it accompanies individuals as they mature and it encourages mutual growth and enrichment through caring and sharing. The Christian family in particular serves as a seedbed for personal maturation according to the standards of divine love. The family is one of the indispensable social subjects for the achievement of a culture of peace. The rights of parents and their primary role in the education of their children in the area of morality and religion must be safeguarded. It is in the family that peacemakers, tomorrow’s promoters of a culture of life and love, are born and nurtured.
