9.2: Doctrine and Practice

II. Doctrine and Practice

A community, a way of life, a system of belief, a liturgical observance, a tradition—Christianity is all of these, and more. Each of these aspects of Christianity has affinities with other faiths, but each also bears unmistakable marks of its Christian origins. Thus, it is helpful, in fact unavoidable, to examine Christian ideas and institutions comparatively, by relating them to those of other religions, but equally important to look for those features that are uniquely Christian.

A. Central Teachings

Any phenomenon as complex and as vital as Christianity is easier to describe historically than to define logically, but such a description does yield some insights into its continuing elements and essential characteristics. One such element is the centrality of the person of Jesus Christ. That centrality is, in one way or another, a feature of all the historical varieties of Christian belief and practice. Christians have not agreed in their understanding and definition of what makes Christ distinctive or unique. Certainly they would all affirm that his life and example should be followed and that his teachings about love and fellowship should be the basis of human relations. Large parts of his teachings have their counterparts in the sayings of the rabbis—that is, after all, what he was—or in the wisdom of Socrates and Confucius. In Christian teaching, Jesus cannot be less than the supreme preacher and exemplar of the moral life, but for most Christians that, by itself, does not do full justice to the significance of his life and work.

What is known of Jesus, historically, is told in the Gospels of the New Testament of the Bible. Other portions of the New Testament summarize the beliefs of the early Christian church. Paul and the other writers of Scripture believed that Jesus was the revealer not only of human life in its perfection but of divine reality itself. See also Christology.

The ultimate mystery of the universe, called by many different names in various religions, was called “Father” in the sayings of Jesus, and Christians therefore call Jesus himself “Son of God.” At the very least, there was in his language and life an intimacy with God and an immediacy of access to God, as well as the promise that, through all that Christ was and did, his followers might share in the life of the Father in heaven and might themselves become children of God. Jesus’ crucifixion and resurrection, to which early Christians referred when they spoke about him as the one who had reconciled humanity to God, made the cross the chief focus of Christian faith and devotion and the principal symbol of the saving love of God the Father.

This love is, in the New Testament and in subsequent Christian doctrine, the most decisive among the attributes of God. Christians teach that God is almighty in dominion over all that is in heaven and on earth, righteous in judgment over good and evil, beyond time and space and change; but above all they teach that “God is love.” The creation of the world out of nothing and the creation of the human race were expressions of that love, and so was the coming of Christ. The classic statement of this trust in the love of God came in the words of Jesus, in the Sermon on the Mount: “Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they?” (Matthew 6:26). Early Christianity found in such words evidence both of the special standing men and women have as children of such a heavenly Father and of the even more special position occupied by Christ. That special position led the first generations of believers to rank him together with the Father—and eventually “the Holy Spirit, whom the Father [sent] in [Christ’s] name”—in the formula used for the administration of baptism and in the several creeds of the first centuries. After controversy and reflection, that confession took the form of the doctrine of God as Trinity. See also Holy Spirit.

Baptism “in the name of the Father and of the Son and of the Holy Spirit,” or sometimes perhaps more simply “in the name of Christ,” has been from the beginning the means of initiation into Christianity. At first it seems to have been administered chiefly to adults after they had professed their faith and promised to amend their lives, but this turned into a more inclusive practice with the baptism of infants. The other universally accepted ritual among Christians is the Eucharist, or Lord’s Supper, in which Christians share in bread and wine and, through them, express and acknowledge the reality of the presence of Christ as they commemorate him in the communion of believers with one another. In the form it acquired as it developed, the Eucharist became an elaborate ceremony of consecration and adoration, the texts of which have been set to music by numerous composers of masses. The Eucharist has also become one of the chief points of conflict among the various Christian churches, which disagree about the “presence” of Christ in the consecrated bread and wine and about the effect of that presence upon those who receive. See also Liturgy; Mass;Mass, Musical Settings of.

Another fundamental component of Christian faith and practice is the Christian community itself—the church. Some scholars question the assumption that Jesus intended to found a church (the word church appears only twice in the Gospels), but his followers were always convinced that his promise to be with them “always, to the close of the age” found its fulfillment in his “mystical body on earth,” the holy catholic (universal) church. The relation of this holy catholic church to the various ecclesiastical organizations of worldwide Christendom is the source of major divisions among these organizations. Roman Catholicism has tended to equate its own institutional structure with the catholic church, as the common usage of the latter term suggests, and some extreme Protestant groups have been ready to claim that they, and they alone, represent the true visible church. Increasingly, however, Christians of all segments have begun to acknowledge that no one group has an exclusive right to call itself “the” church, and they have begun to work toward the reunion of all Christians. See Ecumenical Movement; Protestantism; Roman Catholic Church.

B. Worship

Whatever its institutional form, the community of faith in the church is the primary setting for Christian worship. Christians of all traditions have placed a strong emphasis on private devotion and individual prayer, as Jesus taught. But he also prescribed a form of praying, universally known as the Lord’s Prayer, the opening words of which stress the communal nature of worship: “Our Father, who art in heaven.” Since New Testament times, the stated day for the communal worship of Christians has been the “first day of the week,” Sunday, in commemoration of the resurrection of Christ. Like the Jewish Sabbath, Sunday is traditionally a day of rest. It is also the time when believers gather to hear the reading and preaching of the word of God in the Bible, to participate in the sacraments, and to pray, praise, and give thanks. The needs of corporate worship have been responsible for the composition of thousands of hymns, chorales, and chants, as well as instrumental music, especially for the organ. Since the 4th century, Christian communities have also been constructing special buildings for their worship, thereby helping to shape the history of architecture. See Basilica; Church; Early Christian Art and Architecture; Hymn; Prayer.

C. Christian Life

The instruction and exhortation of Christian preaching and teaching concern all the themes of doctrine and morals: the love of God and the love of neighbor, the two chief commandments in the ethical message of Jesus (see Matthew 22: 34-40). Application of these commandments to the concrete situations of human life, both personal and social, does not produce a uniformity of moral or political behavior. Many Christians, for example, regard all drinking of alcoholic beverages as sinful, whereas others do not. Christians can be found on both the far left and the far right of many contemporary questions, as well as in the middle. Still it is possible to speak of a Christian way of life, one that is informed by the call to discipleship and service. The inherent worth of every person as one who has been created in the image of God, the sanctity of human life and thus of marriage and the family, the imperative to strive for justice even in a fallen world—all of these are dynamic moral commitments that Christians would accept, however much their own conduct may fall short of these norms. It is evident already from the pages of the New Testament that the task of working out the implications of the ethic of love under the conditions of existence has always been difficult, and that there has, in fact, never been a “golden age” in which it was otherwise.

D. Eschatology

There is in Christian doctrine, however, the prospect of such a time, expressed in the Christian hope for everlasting life. Jesus spoke of this hope with such urgency that many of his followers clearly expected the end of the world and the coming of the eternal kingdom in their own lifetimes. Since the 1st century such expectations have tended to ebb and flow, sometimes reaching a fever of excitement and at other times receding to an apparent acceptance of the world as it is. The creeds of the church speak of this hope in the language of resurrection, a new life of participation in the glory of the resurrected Christ. Christianity may therefore be said to be an otherworldly religion, and sometimes it has been almost exclusively that. But the Christian hope has also, throughout the history of the church, served as a motivation to make life on earth conform more fully to the will of God as revealed in Christ.
