§ 80. Marriage is firstly an “intimate partnership of life and love” which is a good for the spouses themselves, while sexuality is “ordered to the conjugal love of man and woman”. It follows that “spouses to whom God has not granted children can have a conjugal life full of meaning, in both human and Christian terms”. Nonetheless, the conjugal union is ordered to procreation “by its very nature”. The child who is born “does not come from outside as something added on to the mutual love of the spouses, but springs from the very heart of that mutual giving, as its fruit and fulfilment”. He or she does not appear at the end of a process, but is present from the beginning of love as an essential feature, one that cannot be denied without disfiguring that love itself. From the outset, love refuses every impulse to close in on itself; it is open to a fruitfulness that draws it beyond itself. Hence no genital act of husband and wife can refuse this meaning, even when for various reasons it may not always in fact beget a new life.
On conjugal love between a man and a woman and the transmission of life
§ 81. A child deserves to be born of that love, and not by any other means, for “he or she is not something owed to one, but is a gift”, which is “the fruit of the specific act of the conjugal love of the parents”. This is the case because, “according to the order of creation, conjugal love between a man and a woman, and the transmission of life are ordered to each other (cf. Gen 1:27-28). Thus the Creator made man and woman share in the work of his creation and, at the same time, made them instruments of his love, entrusting to them the responsibility for the future of mankind, through the transmission of human life”.
On the generation of human life to one variable of an individual’s or a couple’s plans
§ 82. The Synod Fathers stated that “the growth of a mentality that would reduce the generation of human life to one variable of an individual’s or a couple’s plans is clearly evident”. The Church’s teaching is meant to “help couples to experience in a complete, harmonious and conscious way their communion as husband and wife, together with their responsibility for procreating life. We need to return to the message of the Encyclical Humanae Vitae of Blessed Pope Paul VI, which highlights the need to respect the dignity of the person in morally assessing methods of regulating birth… The choice of adoption or foster parenting can also express that fruitfulness which is a characteristic of married life”. With special gratitude the Church “supports families who accept, raise and surround with affection children with various disabilities”.
The family as the sanctuary of life
§ 83. Here I feel it urgent to state that, if the family is the sanctuary of life, the place where life is conceived and cared for, it is a horrendous contradiction when it becomes a place where life is rejected and destroyed. So great is the value of a human life, and so inalienable the right to life of an innocent child growing in the mother’s womb, that no alleged right to one’s own body can justify a decision to terminate that life, which is an end in itself and which can never be considered the “property” of another human being. The family protects human life in all its stages, including its last. Consequently, “those who work in healthcare facilities are reminded of the moral duty of conscientious objection. Similarly, the Church not only feels the urgency to assert the right to a natural death, without aggressive treatment and euthanasia”, but likewise “firmly rejects the death penalty”.
