Gaudium et Spes
88. Christians should cooperate willingly and wholeheartedly in establishing an international order that includes a genuine respect for all freedoms and amicable brotherhood between all. This is all the more pressing since the greater part of the world is still suffering from so much poverty that it is as if Christ Himself were crying out in these poor to beg the charity of the disciples. Do not let men, then, be scandalized because some countries with a majority of citizens who are counted as Christians have an abundance of wealth, whereas others are deprived of the necessities of life and are tormented with hunger, disease, and every kind of misery. The spirit of poverty and charity are the glory and witness of the Church of Christ.
Those Christians are to be praised and supported, therefore, who volunteer their services to help other men and nations. Indeed, it is the duty of the whole People of God, following the word and example of the bishops, to alleviate as far as they are able the sufferings of the modern age. They should do this too, as was the ancient custom in the Church, out of the substance of their goods, and not only out of what is superfluous.
The procedure of collecting and distributing aids, without being inflexible and completely uniform, should nevertheless be carried on in an orderly fashion in dioceses, nations, and throughout the entire world. Wherever it seems convenient, this activity of Catholics should be carried on in unison with other Christian brothers. For the spirit of charity does not forbid, but on the contrary commands that charitable activity be carried out in a careful and orderly manner. Therefore, it is essential for those who intend to dedicate themselves to the services of the developing nations to be properly trained in appropriate institutes.
89. Since, in virtue of her mission received from God, the Church preaches the Gospel to all men and dispenses the treasures of grace, she contributes to the ensuring of peace everywhere on earth and to the placing of the fraternal exchange between men on solid ground by imparting knowledge of the divine and natural law. Therefore, to encourage and stimulate cooperation among men, the Church must be clearly present in the midst of the community of nations both through her official channels and through the full and sincere collaboration of all Christians—a collaboration motivated solely by the desire to be of service to all.
This will come about more effectively if the faithful themselves, conscious of their responsibility as men and as Christians will exert their influence in their own milieu to arouse a ready willingness to cooperate with the international community. Special care must be given, in both religious and civil education, to the formation of youth in this regard.
90. An outstanding form of international activity on the part of Christians is found in the joint efforts which, both as individuals and in groups, they contribute to institutes already established or to be established for the encouragement of cooperation among nations. There are also various Catholic associations on an international level which can contribute in many ways to the building up of a peaceful and fraternal community of nations. These should be strengthened by augmenting in them the number of well qualified collaborators, by increasing needed resources, and by advantageously fortifying the coordination of their energies. For today both effective action and the need for dialogue demand joint projects. Moreover, such associations contribute much to the development of a universal outlook—something certainly appropriate for Catholics. They also help to form an awareness of genuine universal solidarity and responsibility.
Finally, it is very much to be desired that Catholics, in order to fulfill their role properly in the international community, will seek to cooperate actively and in a positive manner both with their separated brothers who together with them profess the Gospel of charity and with all men thirsting for true peace.
The council, considering the immensity of the hardships which still afflict the greater part of mankind today, regards it as most opportune that an organism of the universal Church be set up in order that both the justice and love of Christ toward the poor might be developed everywhere. The role of such an organism would be to stimulate the Catholic community to promote progress in needy regions and international social justice.
91. Drawn from the treasures of Church teaching, the proposals of this sacred synod look to the assistance of every man of our time, whether he believes in God, or does not explicitly recognize Him. If adopted, they will promote among men a sharper insight into their full destiny, and thereby lead them to fashion the world more to man's surpassing dignity, to search for a brotherhood which is universal and more deeply rooted, and to meet the urgencies of our ages with a gallant and unified effort born of love.
Undeniably this conciliar program is but a general one in several of its parts; and deliberately so, given the immense variety of situations and forms of human culture in the world. Indeed while it presents teaching already accepted in the Church, the program will have to be followed up and amplified since it sometimes deals with matters in a constant state of development. Still, we have relied on the word of God and the spirit of the Gospel. Hence we entertain the hope that many of our proposals will prove to be of substantial benefit to everyone, especially after they have been adapted to individual nations and mentalities by the faithful, under the guidance of their pastors.
92. By virtue of her mission to shed on the whole world the radiance of the Gospel message, and to unify under one Spirit all men of whatever nation, race or culture, the Church stands forth as a sign of that brotherhood which allows honest dialogue and gives it vigor.
Such a mission requires in the first place that we foster within the Church herself mutual esteem, reverence and harmony, through the full recognition of lawful diversity. Thus all those who compose the one People of God, both pastors and the general faithful, can engage in dialogue with ever abounding fruitfulness. For the bonds which unite the faithful are mightier than anything dividing them. Hence, let there be unity in what is necessary; freedom in what is unsettled, and charity in any case.
Our hearts embrace also those brothers and communities not yet living with us in full communion; to them we are linked nonetheless by our profession of the Father and the Son and the Holy Spirit, and by the bond of charity. We do not forget that the unity of Christians is today awaited and desired by many, too, who do not believe in Christ; for the farther it advances toward truth and love under the powerful impulse of the Holy Spirit, the more this unity will be a harbinger of unity and peace for the world at large. Therefore, by common effort and in ways which are today increasingly appropriate for seeking this splendid goal effectively, let us take pains to pattern ourselves after the Gospel more exactly every day, and thus work as brothers in rendering service to the human family. For, in Christ Jesus this family is called to the family of the sons of God.
We think cordially too of all who acknowledge God, and who preserve in their traditions precious elements of religion and humanity. We want frank conversation to compel us all to receive the impulses of the Spirit faithfully and to act on them energetically.
For our part, the desire for such dialogue, which can lead to truth through love alone, excludes no one, though an appropriate measure of prudence must undoubtedly be exercised. We include those who cultivate outstanding qualities of the human spirit, but do not yet acknowledge the Source of these qualities. We include those who oppress the Church and harass her in manifold ways. Since God the Father is the origin and purpose of all men, we are all called to be brothers. Therefore, if we have been summoned to the same destiny, human and divine, we can and we should work together without violence and deceit in order to build up the world in genuine peace.
93. Mindful of the Lord's saying: "by this will all men know that you are my disciples, if you have love for one another" (John 13:35), Christians cannot yearn for anything more ardently than to serve the men of the modern world with mounting generosity and success. Therefore, by holding faithfully to the Gospel and benefiting from its resources, by joining with every man who loves and practices justice, Christians have shouldered a gigantic task for fulfillment in this world, a task concerning which they must give a reckoning to Him who will judge every man on the last of days.
Not everyone who cries, "Lord, Lord," will enter into the kingdom of heaven, but those who do the Father's will by taking a strong grip on the work at hand. Now, the Father wills that in all men we recognize Christ our brother and love Him effectively, in word and in deed. By thus giving witness to the truth, we will share with others the mystery of the heavenly Father's love. As a consequence, men throughout the world will be aroused to a lively hope—the gift of the Holy Spirit—that some day at last they will be caught up in peace and utter happiness in that fatherland radiant with the glory of the Lord.
Now to Him who is able to accomplish all things in a measure far beyond what we ask or conceive, in keeping with the power that is at work in us—to Him be glory in the Church and in Christ Jesus, down through all the ages of time without end. Amen. (Eph. 3:20-21).
