Sunday worship on the Sabbath is the key Christian ritual, with special emphasis on the Easter and Christmas ceremonies. Sunday is the day of worship rather than Saturday because Sunday is the day of the Lord’s resurrection. Thus, every Sunday is a little Easter celebration. Worship centers on Bible readings and their interpretation with sermons and testimonials. Prayers, hymns, chants and the Lord’s Supper, or the Eucharistic meal, remain a mainstay of most Christian worship services. The various Christian symbolic actions or sacraments grow out of a Trinitarian baptism based on a belief in Jesus Christ.
The standard collection of twenty-seven books of the New Testament, centers on the good news about Jesus the “Christ,” literally “the anointed one,” and his followers. The collected canon of biblical books during the first four centuries is in itself an indication of how the value of these texts developed slowly and emerged over time. These diverse inspired authors of the second half of the first century of the Christian era provide a basic insight into the thought and practices of the primitive Christian communities. Our shared sacred documents also reveal information about the perceived role of the Holy Spirit in the activities and expectations of the newly forming Christian communities.
