The ecumenical council Vatican II of the Catholic Church is considered authoritative by most Catholics in matters of Christian doctrine. Vatican II took place between 1962 to 1965.
The authority of Vatican II is rejected by many Christians including...
These are some excerpts I find particularly relevant.
Decree on Ecumenism — Catholics and other Christians
Decree on Ecumenism
Note: The term "separated brethren" refers to Protestant and Orthodox christians — to non-Catholic christians.
The restoration of unity among all Christians is one of the principal concerns of the Second Vatican Council. Christ the Lord founded one Church and one Church only. However, many Christian communions present themselves to men as the true inheritors of Jesus Christ; all indeed profess to be followers of the Lord but differ in mind and go their different ways, as if Christ Himself were divided. Such division openly contradicts the will of Christ, scandalizes the world, and damages the holy cause of preaching the Gospel to every creature.
Chapter 1 — Catholic Principles on Ecumenism
Even in the beginnings of this one and only Church of God there arose certain rifts, which the Apostle strongly condemned. But in subsequent centuries much more serious dissensions made their appearance and quite large communities came to be separated from full communion with the Catholic Church — for which, often enough, men of both sides were to blame. The children who are born into these Communities and who grow up believing in Christ cannot be accused of the sin involved in the separation, and the Catholic Church embraces upon them as brothers, with respect and affection. For men who believe in Christ and have been truly baptized are in communion with the Catholic Church even though this communion is imperfect. . . . It remains true that all who have been justified by faith in Baptism are members of Christ's body, and have a right to be called Christian, and so are correctly accepted as brothers by the children of the Catholic Church. . . . Our separated brethren, whether considered as individuals or as Communities and Churches [Churches refers to Orthodox; Communities refers to Protestant], are not blessed with that unity which Jesus Christ wished to bestow on all those who through Him were born again into one body.
Catholics, in their ecumenical work, must assuredly be concerned for their separated brethren, praying for them, keeping them informed about the Church, making the first approaches toward them. . . . Although the Catholic Church has been endowed with all divinely revealed truth and with all means of grace, yet its members fail to live by them with all the fervor that they should, so that the radiance of the Church's image is less clear in the eyes of our separated brethren and of the world at large, and the growth of God's kingdom is delayed. . . . Catholics must gladly acknowledge and esteem the truly Christian endowments from our common heritage which are to be found among our separated brethren. . . . Nor should we forget that anything wrought by the Grace Of The Holy Spirit in the hearts of our separated brethren can be a help to our own edification.
Chapter 2 — The Practice of Ecumenism
In certain special circumstances, such as the prescribed prayers "for unity," and during ecumenical gatherings, it is allowable, indeed desirable that Catholics should join in prayer with their separated brethren. . . . Yet worship in common . . . is not to be considered as a means to be used indiscriminately for the restoration of Christian unity.
We must get to know the outlook of our separated brethren.
Chapter 3 — Churches and Ecclesial Communities Separated From the Roman Apostolic See — Separated Churches and Ecclesial Communities in the West
Other divisions arose more than four centuries later in the West, stemming from the events which are usually referred to as "The Reformation." As a result, many Communions, national or confessional, were separated from the Roman See.
However, since these Churches and ecclesial Communities, on account of their different origins, and different teachings in matters of doctrine on the spiritual life, vary considerably not only with us, but also among themselves, the task of describing them at all adequately is extremely difficult. . . . It must however be admitted that in these Churches and ecclesial Communities there exist important differences from the Catholic Church, not only of an historical, sociological, psychological and cultural character, but especially in the interpretation of revealed truth.
Our thoughts turn first to those Christians who make open confession of Jesus Christ as God and Lord and as the sole Mediator between God and men, to the glory of the one God, Father, Son and Holy Spirit. We are aware indeed that there exist considerable divergences from the doctrine of the Catholic Church concerning Christ Himself, the Word of God made flesh, the work of redemption, and consequently, concerning the mystery and ministry of the Church, and the role of Mary in the plan of salvation. But we rejoice to see that our separated brethren look to Christ as the source and center of Church unity.
A love and reverence of Sacred Scripture which might be described as devotion, leads our brethren to a constant meditative study of the sacred text. . . . But while the Christians who are separated from us hold the divine authority of the Sacred Books, they differ from ours—some in one way, some in another—regarding the relationship between Scripture and the Church. For, according to Catholic belief, the authentic teaching authority of the Church has a special place in the interpretation and preaching of the written word of God.
Whenever the Sacrament of Baptism is duly administered as Our Lord instituted it, and is received with the right dispositions, a person is truly incorporated into the crucified and glorified Christ. . . . The ecclesial Communities which are separated from us lack the fullness of unity with us flowing from Baptism, and though we believe they have not retained the proper reality of the eucharistic mystery in its fullness, especially because of the absence of the sacrament of Orders.
The daily Christian life of these brethren is nourished by their faith in Christ and strengthened by the grace of Baptism and by hearing the word of God. This shows itself in their private prayer, their meditation on the Bible, in their Christian family life, and in the worship of a community gathered together to praise God. Moreover, their form of worship sometimes displays notable features of the liturgy which they shared with us of old. Their faith in Christ bears fruit in praise and thanksgiving for the blessings received from the hands of God. Among them, too, is a strong sense of justice and a true charity toward their neighbor. This active faith has been responsible for many organizations for the relief of spiritual and material distress, the furtherance of the education of youth, the improvement of the social conditions of life, and the promotion of peace throughout the world.
Declaration on the Relation of the Church to Non-Christian Religions
From ancient times down to the present, there is found among various peoples a certain perception of that hidden power which hovers over the course of things and over the events of human history; at times some indeed have come to the recognition of a Supreme Being, or even of a Father. . . . . Thus in Hinduism, men contemplate the divine mystery and express it through an inexhaustible abundance of myths and through searching philosophical inquiry. They seek freedom from the anguish of our human condition either through ascetical practices or profound meditation or a flight to God with love and trust.
Again, Buddhism, in its various forms, realizes the radical insufficiency of this changeable world; it teaches a way by which men, in a devout and confident spirit, may be able either to acquire the state of perfect liberation, or attain, by their own efforts or through higher help, supreme illumination. Likewise, other religions found everywhere try to counter the restlessness of the human heart, each in its own manner, by proposing "ways," comprising teachings, rules of life, and sacred rites. The Catholic Church rejects nothing that is true and holy in these religions. She regards with sincere reverence those ways of conduct and of life, those precepts and teachings which, though differing in many aspects from the ones she holds and sets forth, nonetheless often reflect a ray of that Truth which enlightens all men. Indeed, she proclaims, and ever must proclaim Christ "the way, the truth, and the life" (John 14:6), in whom men may find the fullness of religious life, in whom God has reconciled all things to Himself.
The Church regards with esteem also the Moslems. They adore the one God, living and subsisting in Himself; merciful and all- powerful, the Creator of heaven and earth, who has spoken to men; they take pains to submit wholeheartedly to even His inscrutable decrees, just as Abraham, with whom the faith of Islam takes pleasure in linking itself, submitted to God. Though they do not acknowledge Jesus as God, they revere Him as a prophet. They also honor Mary, His virgin Mother; at times they even call on her with devotion. In addition, they await the day of judgment when God will render their deserts to all those who have been raised up from the dead. Finally, they value the moral life and worship God especially through prayer, almsgiving and fasting. Since in the course of centuries not a few quarrels and hostilities have arisen between Christians and Moslems, this sacred synod urges all to forget the past and to work sincerely for mutual understanding and to preserve as well as to promote together for the benefit of all mankind social justice and moral welfare, as well as peace and freedom.
As the sacred synod searches into the mystery of the Church, it remembers the bond that spiritually ties the people of the New Covenant to Abraham's stock. Thus the Church of Christ acknowledges that, according to God's saving design, the beginnings of her faith and her election are found already among the Patriarchs, Moses and the prophets. She professes that all who believe in Christ—Abraham's sons according to faith—are included in the same Patriarch's call, and likewise that the salvation of the Church is mysteriously foreshadowed by the chosen people's exodus from the land of bondage. The Church, therefore, cannot forget that she received the revelation of the Old Testament through the people with whom God in His inexpressible mercy concluded the Ancient Covenant. Nor can she forget that she draws sustenance from the root of that well-cultivated olive tree onto which have been grafted the wild shoots, the Gentiles.
Indeed, the Church believes that by His cross Christ, Our Peace, reconciled Jews and Gentiles. making both one in Himself. . . . As Holy Scripture testifies, Jerusalem did not recognize the time of her visitation, nor did the Jews in large number, accept the Gospel; indeed not a few opposed its spreading. Nevertheless, God holds the Jews most dear for the sake of their Fathers. . . . True, the Jewish authorities and those who followed their lead pressed for the death of Christ; still, what happened in His passion cannot be charged against all the Jews, without distinction, then alive, nor against the Jews of today. Although the Church is the new people of God, the Jews should not be presented as rejected or accursed by God, as if this followed from the Holy Scriptures. . . . Furthermore, in her rejection of every persecution against any man, the Church, mindful of the patrimony she shares with the Jews and moved not by political reasons but by the Gospel's spiritual love, decries [condemns] hatred, persecutions, displays of anti-Semitism, directed against Jews at any time and by anyone.
No foundation therefore remains for any theory or practice that leads to discrimination between man and man or people and people, so far as their human dignity and the rights flowing from it are concerned. The Church reproves, as foreign to the mind of Christ, any discrimination against men or harassment of them because of their race, color, condition of life, or religion.
Declaration on Religious Freedom
On the Right of the Person and of Communities to Social and Civil Freedom in Matters Religious
This Vatican Council declares that the human person has a right to religious freedom. This freedom means that all men are to be immune from coercion on the part of individuals or of social groups and of any human power, in such wise that no one is to be forced to act in a manner contrary to his own beliefs, whether privately or publicly, whether alone or in association with others, within due limits.
The freedom or immunity from coercion in matters religious which is the endowment of persons as individuals is also to be recognized as their right when they act in community. Religious communities are a requirement of the social nature both of man and of religion itself. . . . Religious communities also have the right not to be hindered, either by legal measures or by administrative action on the part of government, in the selection, training, appointment, and transferral of their own ministers, in communicating with religious authorities and communities abroad, in erecting buildings for religious purposes, and in the acquisition and use of suitable funds or properties.
Religious communities also have the right not to be hindered in their public teaching and witness to their faith, whether by the spoken or by the written word. However, in spreading religious faith and in introducing religious practices everyone ought at all times to refrain from any manner of action which might seem to carry a hint of coercion or of a kind of persuasion that would be dishonorable or unworthy, especially when dealing with poor or uneducated people. Such a manner of action would have to be considered an abuse of one's right and a violation of the right of others.
The family, since it is a society in its own original right, has the right freely to live its own domestic religious life under the guidance of parents. Parents, moreover, have the right to determine, in accordance with their own religious beliefs, the kind of religious education that their children are to receive. Government, in consequence, must acknowledge the right of parents to make a genuinely free choice of schools and of other means of education, and the use of this freedom of choice is not to be made a reason for imposing unjust burdens on parents, whether directly or indirectly. Besides, the right of parents are violated, if their children are forced to attend lessons or instructions which are not in agreement with their religious beliefs, or if a single system of education, from which all religious formation is excluded, is imposed upon all.
The protection and promotion of the inviolable rights of man ranks among the essential duties of government. Therefore government is to assume the safeguard of the religious freedom of all its citizens, in an effective manner, by just laws and by other appropriate means. Government is also to help create conditions favorable to the fostering of religious life. . . . Finally, government is to see to it that equality of citizens before the law, which is itself an element of the common good, is never violated, whether openly or covertly, for religious reasons. Nor is there to be discrimination among citizens.
The right to religious freedom is exercised in human society: hence its exercise is subject to certain regulatory norms. In the use of all freedoms the moral principle of personal and social responsibility is to be observed. In the exercise of their rights, individual men and social groups are bound by the moral law to have respect both for the rights of others and for their own duties toward others and for the common welfare of all.
It is one of the major tenets of Catholic doctrine that man's response to God in faith must be free: no one therefore is to be forced to embrace the Christian faith against his own will.
In human society and in the face of government the Church claims freedom for herself in her character as a spiritual authority, established by Christ the Lord, upon which there rests, by divine mandate, the duty of going out into the whole world and preaching the Gospel to every creature. The Church also claims freedom for herself in her character as a society of men who have the right to live in society in accordance with the precepts of the Christian faith. . . . The Christian faithful, in common with all other men, possess the civil right not to be hindered in leading their lives in accordance with their consciences.
Dogmatic Constitution on Divine Revelation
Chapter 2 — Handing on Divine Revelation
In order to keep the Gospel forever whole and alive within the Church, the Apostles left bishops as their successors, "handing over" to them "the authority to teach in their own place." This sacred tradition, therefore, and Sacred Scripture of both the Old and New Testaments. . . .
Sacred tradition and Sacred Scripture form one sacred deposit of the word of God, committed to the Church. . . . But the task of authentically interpreting the word of God, whether written or handed on, has been entrusted exclusively to the living teaching office of the Church [magisterium], whose authority is exercised in the name of Jesus Christ. This teaching office [magisterium] is not above the word of God, but serves it, teaching only what has been handed on, listening to it devoutly, guarding it scrupulously and explaining it faithfully in accord with a divine commission and with the help of the Holy Spirit, it draws from this one deposit of faith everything which it presents for belief as divinely revealed. . . . Sacred tradition, Sacred Scripture and the teaching authority of the Church [magisterium], in accord with God's most wise design, are so linked and joined together that one cannot stand without the others.
However, since God speaks in Sacred Scripture through men in human fashion, the interpreter of Sacred Scripture, in order to see clearly what God wanted to communicate to us, should carefully investigate what meaning the sacred writers really intended, and what God wanted to manifest by means of their words.
Chapter 3 — Sacred Scripture, Its Inspiration and Divine Interpretation
To search out the intention of the sacred writers, attention should be given, among other things, to "literary forms." For truth is set forth and expressed differently in texts which are variously historical, prophetic, poetic, or of other forms of discourse. The interpreter must investigate what meaning the sacred writer intended to express and actually expressed in particular circumstances by using contemporary literary forms in accordance with the situation of his own time and culture. For the correct understanding of what the sacred author wanted to assert, due attention must be paid to the customary and characteristic styles of feeling, speaking and narrating which prevailed at the time of the sacred writer, and to the patterns men normally employed at that period in their everyday dealings with one another.
But, since Holy Scripture must be read and interpreted in the sacred spirit in which it was written, no less serious attention must be given to the content and unity of the whole of Scripture if the meaning of the sacred texts is to be correctly worked out. The living tradition of the whole Church must be taken into account along with the harmony which exists between elements of the faith. It is the task of exegetes to work according to these rules toward a better understanding and explanation of the meaning of Sacred Scripture, so that through preparatory study the judgment of the Church may mature. For all of what has been said about the way of interpreting Scripture is subject finally to the judgment of the Church, which carries out the divine commission and ministry of guarding and interpreting the word of God.
Chapter 6 — Sacred Scripture in the Life of the Church
Easy access to Sacred Scripture should be provided for all the Christian faithful.
Declaration on Christian Education
The Authors of Education
Since parents have given children their life, they are bound by the most serious obligation to educate their offspring and therefore must be recognized as the primary and principal educators. . . . in a special way, the duty of educating belongs to the Church, not merely because she must be recognized as a human society capable of educating, but especially because she has the responsibility of announcing the way of salvation to all men, of communicating the life of Christ to those who believe, and, in her unfailing solicitude, of assisting men to be able to come to the fullness of this life.
The Duties and Rights of Parents
Parents who have the primary and inalienable right and duty to educate their children must enjoy true liberty in their choice of schools. Consequently, the public power, which has the obligation to protect and defend the rights of citizens, must see to it, in its concern for distributive justice, that public subsidies are paid out in such a way that parents are truly free to choose according to their conscience the schools they want for their children.
