In the light of these and other texts of the New Testament it is possible to understand what is meant by the “civilization of love”, and why the family is organically linked to this civilization. If the first “way of the Church” is the family, it should also be said that the civilization of love is also the “way of the Church”, which journeys through the world and summons families to this way; it summons also other social, national and international institutions, because of families and through families. The family in fact depends for several reasons on the civilization of love, and finds therein the reasons for its existence as family. And at the same time the family is the centre and the heart of the civilization of love.
Yet there is no true love without an awareness that God “is Love”—and that man is the only creature on earth which God has called into existence “for its own sake”. Created in the image and likeness of God, man cannot fully “find himself” except through the sincere gift of self. Without such a concept of man, of the person and the “communion of persons” in the family, there can be no civilization of love; similarly, without the civilization of love it is impossible to have such a concept of person and of the communion of persons. The family constitutes the fundamental “cell” of society. But Christ—the “vine” from which the “branches” draw nourishment—is needed so that this cell will not be exposed to the threat of a kind of cultural uprooting which can come both from within and from without. Indeed, although there is on the one hand the “civilization of love”, there continues to exist on the other hand the possibility of a destructive “anti-civilization”, as so many present trends and situations confirm.
Who can deny that our age is one marked by a great crisis, which appears above all as a profound “crisis of truth“? A crisis of truth means, in the first place, a crisis of concepts. Do the words “love”, “freedom”, “sincere gift”, and even “person” and “rights of the person”, really convey their essential meaning? This is why the Encyclical on the “splendour of truth” (Veritatis Splendor) has proved so meaningful and important for the Church and for the world—especially in the West. Only if the truth about freedom and the communion of persons in marriage and in the family can regain its splendour, will the building of the civilization of love truly begin and will it then be possible to speak concretely—as the Council did—about “promoting the dignity of marriage and the family”.
