The Bible gives one consequential answer to these two queries: the human being is created in the image of God, and God himself is love. It is therefore the vocation to love that makes the human person an authentic image of God: man and woman come to resemble God to the extent that they become loving people.
This fundamental connection between God and the person gives rise to another: the indissoluble connection between spirit and body: in fact, the human being is a soul that finds expression in a body and a body that is enlivened by an immortal spirit.
The body, therefore, both male and female, also has, as it were, a theological character: it is not merely a body; and what is biological in the human being is not merely biological but is the expression and the fulfilment of our humanity.
Likewise, human sexuality is not juxtaposed to our being as person but part of it. Only when sexuality is integrated within the person does it successfully acquire meaning.
Thus, these two links, between the human being with God and in the human being, of the body with the spirit, give rise to a third: the connection between the person and the institution.
Indeed, the totality of the person includes the dimension of time, and the person’s “yes” is a step beyond the present moment: in its wholeness, the “yes” means “always”, it creates the space for faithfulness. Only in this space can faith develop, which provides a future and enables children, the fruit of love, to believe in human beings and in their future in difficult times.
The freedom of the “yes”, therefore, reveals itself to be freedom capable of assuming what is definitive: the greatest expression of freedom is not the search for pleasure without ever coming to a real decision; this apparent, permanent openness seems to be the realization of freedom, but it is not true. The true expression of freedom is the capacity to choose a definitive gift in which freedom, in being given, is fully rediscovered.
In practice, the personal and reciprocal “yes” of the man and the woman makes room for the future, for the authentic humanity of each of them. At the same time, it is an assent to the gift of a new life.
Therefore, this personal “yes” must also be a publicly responsible “yes”, with which the spouses take on the public responsibility of fidelity, also guaranteeing the future of the community. None of us, in fact, belongs exclusively to himself or herself: one and all are therefore called to take on in their inmost depths their own public responsibility.
Marriage as an institution is thus not an undue interference of society or of authority. The external imposition of form on the most private reality of life is instead an intrinsic requirement of the covenant of conjugal love and of the depths of the human person.
