In the early centuries of Christianity, the shift from observing the Jewish Sabbath (Saturday) to celebrating Sunday as the “Lord’s Day” marked a significant transition. This change was influenced by several factors, including persecution, theological reflection, and the centrality of Jesus’ resurrection.
1. Persecution from Jewish Authorities
Early Christians, many of whom were Jewish, initially observed the Sabbath. However, tensions arose as they proclaimed Jesus as the Messiah, causing some Jewish leaders to view them as heretical. Persecution followed, such as Paul’s pre-conversion attempts to imprison Christians (Acts 9:1-2). To avoid conflict and further persecution, early Christians began distancing themselves from Jewish customs, including the Sabbath.
2. The Resurrection and the Lord’s Day
Theological significance played a major role in the shift. Jesus’ resurrection, which occurred on a Sunday, was central to the Christian faith. Early Christians gathered on Sunday to commemorate this event, celebrating the new life it represented. In the New Testament, Sunday worship was emphasized (Acts 20:7, 1 Corinthians 16:2), and the practice of meeting on the first day of the week gradually replaced Sabbath observance.
3. Gentile Converts and Christian Identity
As Christianity spread among Gentiles, who had no historical connection to Jewish customs, the need to distinguish Christian identity became more apparent. This move away from the Jewish Sabbath allowed early Christians to establish a distinct religious identity in the Roman world, particularly as they faced growing persecution from the Roman Empire.
4. Constantine and Sunday as a Day of Rest
In AD 321, Emperor Constantine, the first Roman emperor to convert to Christianity, formalized Sunday as a day of rest. This decree solidified Sunday as the Christian day of worship, both for religious and civil purposes. By this point, Sunday worship was widely accepted as a central practice in the Christian tradition.
Conclusion: The Evolution of Sunday Worship
The shift from the Jewish Sabbath to Sunday worship was gradual and shaped by multiple factors, including Jewish persecution, the theological importance of Jesus' resurrection, and the desire to form a distinct Christian identity. By the time of Constantine’s decree, Sunday had become the recognized day of Christian worship, symbolizing the new covenant in Christ and setting Christians apart from Jewish practices. Today, Sunday remains the central day of worship for most Christian denominations worldwide.
