Ad Gentes §12

¹² The presence of the Christian faithful in these human groups should be inspired by that charity with which God has loved us, and with which He wills that we should love one another (cf. 1 John 4:11). Christian charity truly extends to all, without distinction of race, creed, or social condition: it looks for neither gain nor gratitude. For as God loved us with an unselfish love, so also the faithful should in their charity care for the human person himself, loving him with the same affection with which God sought out man. Just as Christ, then, went about all the towns and villages, curing every kind of disease and infirmity as a sign that the kingdom of God had come (cf. Matt. 9:35ff; Acts 10:38), so also the Church, through her children, is one with men of every condition, but especially with the poor and the afflicted. For them, she gladly spends and is spent (cf. 2 Cor. 12:15), sharing in their joys and sorrows, knowing of their longings and problems, suffering with them in death's anxieties. To those in quest of peace, she wishes to answer in fraternal dialogue, bearing them the peace and the light of the Gospel. Let Christians labor and collaborate with others in rightly regulating the affairs of social and economic life. With special care, let them devote themselves to the education of children and young people by means of different kinds of schools, which should be considered not only as the most excellent means of forming and developing Christian youth, but also as a valuable public service, especially in the developing nations, working toward the uplifting of human dignity, and toward better living conditions. Furthermore, let them take part in the strivings of those peoples who, waging war on famine, ignorance, and disease, are struggling to better their way of life and to secure peace in the world. In this activity, the faithful should be eager to offer prudent aid to projects sponsored by public and private organizations, by governments, by various Christian communities, and even by non - Christian religions. However, the Church has no desire at all to intrude itself into the government of the earthly city. It claims no other authority than that of ministering to men with the help of God, in a spirit of charity and faithful service (cf. Matt. 20:26; 23:11). Closely united with men in their life and work, Christ's disciples hope to render to others true witness of Christ, and to work for their salvation, even where they are not able to announce Christ fully. For they are not seeking a mere material progress and prosperity for men, but are promoting their dignity and brotherly union, teaching those religious and moral truths which Christ illumined with His light; and in this way, they are gradually opening up a fuller approach to God. Thus they help men to attain to salvation by love for God and neighbor, and the mystery of Christ begins to shine forth, in which there appears the new man, created according to God (cf. Eph. 4:24), and in which the charity of God is revealed. ARTICLE 2: Preaching the Gospel and Gathering together the People of God
