But the commandment "you shall not kill" establishes only the point of departure of a journey to true freedom, a journey which must lead to the active promotion of life, the development of attitudes and modes of behavior which serve life. It is to this positive and constructive prospect that the fourth and final chapter of the document of Pope John Paul II is devoted: "for a new culture of human life."
First of all, the pope points out that the "Gospel of life" is at the heart of the evangelizing mission of the church, which must proclaim Jesus, the "Word of life" (1 Jn. 1:1), the one in whom "the life was made manifest" (1 Jn. 1:2). The church, defined in a new and expressive way as "the people of life," has the task of proclaiming, celebrating and serving life.
Against doubts, skepticism, obscurity and falsehoods, it is a question of proclaiming in its entirety the joyful message of the value of life; the commandment "you shall not kill" is also part of this message. Ever nourished by the word of God, the church has the primary task of ensuring that the Gospel of life reaches the heart of every man and woman, and that it finds its way into the hidden recesses of the whole of society.
She is called also to celebrate the gift of life, considering it with a contemplative and grateful spirit in the light of God's love made manifest in his Son Jesus. The sacraments of the church in an eminent manner, but also the many rituals of various popular and cultural traditions as well as those of everyday life must be means of experiencing joy for this gift, means which help to sustain people in moments of trial and by which their gaze is fixed on the Creator, from whom life comes and to whom it returns.
The mission of the Christian and of the church on behalf of life is fulfilled through the service of charity because charity leads us "to show care for all life and for the life of everyone" (No. 87), with a profound attitude of solidarity in every condition and situation, without prejudice or discrimination. Mention is made of the extraordinary history of charity in the church, which introduced into society a host of organizations at the service of life. The Holy Father exhorts us to strengthen and continue today the numerous projects which have been undertaken in this regard, calling for creative innovation in responding adequately to new challenges. In the area of professional health care, volunteer services, education, social involvement and political commitment and in the face of complex demographic problems, it is a question of fostering mature attitudes and finding solutions which respect life.
In particular, at the center of attention must be the family, the "sanctuary of life," in which life is welcomed, nourished, brought up and supported, and taken care of in sickness. However, the family needs to be helped by a social context which is favorable to these values and by policies which promote its primary and irreplaceable role.
It is a question, the pope affirms, of bringing about a true transformation of culture: the promotion of a "culture of life," in which human freedom will find its authentic meaning by joining forces with truth, life and love. This culture needs new lifestyles which will show respect for the dignity of every individual, especially the weakest, which will recognize the value of human sexuality in the development of the person, and which will accept the mysterious meaning of suffering and of death. A very special task is entrusted to women, who are particularly close to the mystery of life, who are called to be its guardians and to reveal its fruitfulness when that task matures into relationships marked by unselfish giving and willing service. These are the demands of a "new feminism," which, free from individualism, will favor the culture of life. The pope addresses particularly moving words to women who have had abortions. He invites them to be open to repentance, with humility and trust (cf. No. 99). Prayer and fasting, finally, are the great resources which will bring about the purification of all hearts in this great undertaking of proclaiming the Gospel of life on behalf of the whole of human society and for the sake of peace (No. 101).
This important magisterial document of Pope John Paul II closes with a trusting appeal to Mary, the "mother of life." Contemplating the scene in the Book of Revelation of the struggle between the woman who is about to give birth and the dragon which sets a snare for the life of the child, the pope invites us to recognize that throughout history "life is always at the center of a great struggle" (No. 104). But in the mutual relationship between the motherhood of Mary and her own motherhood toward all men and women, the church finds a source of great hope. Mary is the "living word of consolation" on history's difficult journey: To her, with filial confidence, the pope entrusts the cause of life.
