The forms of Christian worship changed and developed considerably during the first four centuries of its existence, not least from a distinctive local or regional diversity to an increasing standardization of practice throughout the ancient world. One of the major factors influencing these changes was the eventual adoption of the New Testament as the Christian scripture, and another was the emergence of the church into public life early in the 4th century. Rites of initiation chiefly involving baptism in water marked the entry of new converts into the community of believers. The central observance was the Eucharist, celebrated every Sunday from at least the end of the 1st century. This was supplemented by services of the word on certain days of the week and by regular times of prayer each day undertaken by individuals or small groups of believers. Annual festal celebrations, the majority of which were associated with the anniversaries of martyrs and others who had died, also increased in number as time passed.
Christians understood the worship that they offered through Jesus Christ to be the spiritual fulfillment of the sacrificial cult of the Old Testament. Although at first insisting that they were not a religion like others around them—indeed, they were regarded as atheists by their contemporaries—they ultimately came to adopt the language, images, and terminology of standard religious discourse once their persecution had ceased and the Church had emerged as a cultus publicus in the 4th century. This also coincided with a shift from an understanding of worship as an essentially corporate action presided over by its appointed ministers to one where those ministers were seen as carrying out its liturgy on behalf of the people.

Medieval Christian Liturgy
Joanne M. Pierce
The liturgy of the medieval Christian West (ca. 600–1500) provided the structure around which life in Western Europe was structured for almost a thousand years. Rooted in Christian antiquity, in the early central liturgical structures of Initiation and Eucharist, the private and public observance of daily prayer, and the development of a liturgical year, the long medieval period that followed saw a broadening elaboration and expansion of the liturgical life of Christians in many different directions. By the year 1200, theologians had defined seven of the Church’s liturgical rites as primary sacraments: Baptism and Confirmation (from the ancient initiation sequence); Eucharist; Penance (with the emphasis on private confession of sins); Ordination (through various minor orders to the three major orders of deacon, presbyter, and bishop); Extreme Unction (anointing of the sick, now reserved for the gravely ill); and Matrimony (as the liturgical rites for the originally domestic rituals of marriage become more elaborate and set in the church rather than the home). A more fulsome cycle of the liturgical year developed around the ancient feasts of Easter, Pentecost, Christmas, and Epiphany, augmented by an elaborate calendar of commemorations and feasts of saints. Monastic influence resulted in a daily round of liturgical prayer, the Divine Office, in which various “hours” of prayer during the day and night were marked by liturgical “offices” of psalmody and scripture—some longer, others more brief. One of the major ways this liturgical growth and diversity can be studied is through an examination of the various liturgical books compiled and used during these medieval centuries, books used for the celebration of the Eucharist (the Mass), for the Divine Office, and for other liturgical rites. In addition to the volumes containing rubrics and prayers for liturgical celebrations, a separate cluster of books contained music to be used during these rites, in a style known as chant; Gregorian chant became the dominant form. The full impact of medieval liturgy as it was experienced in the Western Europe, however, extended far beyond the “bare bones” contained in these books, intertwined as it was with the development of art and architecture, law and commerce, and the political/socio-economic developments that would take Christian society and religion from the twilight of late antiquity to the dawn of early modernity.

The “Classic” Age of Christian Worship, 4th–6th Century
John F. Baldovin
The 4th–6th centuries can be considered a classic period in the development of Christian worship. During this time many of the liturgical forms that are still recognizable today were consolidated: the architectural disposition of church buildings, the shape of the Eucharist and the various traditions of the eucharistic prayer, the rites of initiation, the annual liturgical cycle (calendar), and the rites associated with ordination, weddings, the anointing of the sick, penance, and the burial of the dead. This was the period in which the great diversity and variety that characterized the first Christian centuries gradually settled into the basic structures that are familiar today. At the same time, it was the period of the development of the great rites of Christian worship that were centered on the major cities of the Roman Empire: Antioch, Alexandria, Constantinople, Edessa, Jerusalem, and Rome. The new diversity of these rites often corresponded to the various languages in which they were celebrated: Greek, Syriac, Coptic, and Latin.

Liturgical Vestments, Vessels, and Objects in Christian Worship
Joanne M. Pierce
Any history of Christian liturgy must address the origins and development of the various material elements that are used during these celebrations. These have their own specific history, just as does the architectural and artistic context of the liturgy. Many of the specialized garments, or vestments, worn by ministers during liturgical services in several contemporary Christian churches originated in elements of ordinary or honorific dress used in the ancient Roman Empire. Over the course of several centuries, the style and type of vestments used in Western Christianity diverged from those used in Eastern Christianity, until today the differences are more striking than the similarities, even in shared individual elements like the stole and the chasuble. In addition, different kinds of vestments are used by different ministers (for example, the deacon, priest, or bishop) and in different kinds of sacramental and liturgical ceremonies. What a minister might wear at one service, for example evening prayer or the administration of baptism, might not be the same as those expected for the celebration of the Eucharist (the Mass, the holy communion, or the divine liturgy). The same is true for the essential vessels used during the celebration of the Eucharist: the chalice to hold the wine, and the paten, or plate, on which rests the bread to be blessed. Both of these have developed in distinctive styles in both West and East over time. The same is true of many of the other vessels and implements needed for the Eucharist and those used in other liturgical services. Examples include containers designed to hold water, oil, or incense as well as the number and style of altar cloths, veils, and candles utilized at different times and places.

Byzantine and Slavic Orthodoxy
Alexander Rentel
The Byzantine-Slav liturgical tradition emerged as an aggregate rite from the diverse liturgical practices of the Eastern Mediterranean from the early 4th century. This tradition developed around the city of Constantinople but was also influenced by the liturgical traditions of Jerusalem and the monasteries surrounding Jerusalem. While Constantinople remained the center of this tradition, it also found its home and developed in unique ways throughout the Mediterranean and the Balkan Peninsula, into Ukraine and Russia, and eventually throughout the world.
The liturgical tradition itself weaves together the diverse practices of monastic and urban worship, creating very much a hybrid rite. The daily office, primarily drawn from monastic practices, utilizes a mix of invariable texts, prayers, psalmody, and composed hymns of ancient provenance as well as a wide array of variable hymns of different origins and genre. Throughout these services, the monastic elements stand side by side with remnants of the urban cathedral worship. The Divine Liturgy, the Eucharist service, has at its core prayers that go back to the classic patristic age of the church, the 4th and 5th centuries. The entire service, however, betrays multiple layers of influence on its development, ranging from practices of the imperial cult of late antiquity to popular piety.
All these elements have come together through organic development and, at times, directed reform to form a vast liturgical tradition with rich textures and complex nuances of meaning.
