The East Syrian Christians engaged in widespread missionary activity across the Asian continent, but the rise of Islam reduced their communities to small remnants. The liturgy of these churches is doxological in character, filled with expressions of praise and emphasizing the fulfillment of Christian hope in the kingdom of heaven.
The liturgical traditions of the East derive ultimately from the forms of worship used in Antioch and Alexandria. As with all ancient Christian liturgies, the Service of the Word led into the sacramental offering of the Eucharist. The Eastern traditions comprise the East and West Syrian, the Byzantine (including the Greek and Russian Orthodox), the Armenian, and the Coptic/Ethiopian.
The fundamental pattern of early Christian worship continued to develop through the fourth and fifth centuries. However, “families” of liturgical practice began to emerge, and styles of worship varied from one Christian region to the other. By this time, one can begin to speak of “Eastern” and “Western” characteristics of Christian liturgy.
Worship during the second and third centuries continued to follow the course set by New Testament liturgical traditions. Consequently, the discussion of worship during this period centered on the significance of baptism and of the Eucharist, understood in its full content of the service of Word and of the Lord’s table.
Worship in the New Testament period was ordered around baptism and the Eucharist. Baptism marks the entrance of the believer into the worshiping community, while the Lord’s Supper, together with the teaching of the Scriptures, forms the content of the worship gathering.
The Revelation to John makes dramatic use of the rich symbolism of the sacrificial ritual of the Jewish temple. A comparison of the language and imagery of the book of Revelation with the Divine Liturgy of the Orthodox churches suggests that in the Revelation we see an early stage in the development of Christian liturgy, especially that of the Eastern churches.
The New Testament spiritual gifts—especially prophecy, tongues, and interpretation, along with healing—continued to manifest themselves in the life of the church up to and beyond the fourth century. Evidence in the literature from this period indicates that these gifts were respected among the “established” church leadership, referred to by important theologians, and practiced especially throughout the “underground” church.
Ordination is rooted in the need for order within the Christian community. It tends both to reflect and to shape the church’s life and witness amid changing historical circumstances. An important development in the post–New Testament period was the emergence of a three-office structure for ordained ministry (bishop, presbyter, deacon) and the subsequent transformation of that structure into a more authoritarian one as the church came to assume a public role in a wider cultural context.
Jewish table prayer, thought by some historians of liturgy to be the antecedent of the early Christian eucharistic prayer, evidences a threefold pattern of praise, remembrance, and petition. In a general way this sequence corresponds to the formula “Father, Son, and Holy Spirit” in Christian worship. Thus, liturgical practice may have helped to shape classical Christian Trinitarianism.
The New Testament records that Jesus and his disciples, as well as early Christian preachers such as Paul and Barnabas, attended the synagogue assemblies. The true influence of the synagogue on early Christian worship, however, is difficult to assess. Contacts between Christians and Jews continued up to the fourth century; thus, in the post–New Testament period Jewish influence can be seen in the development of Christian prayer and the Christian calendar.
