Definition and Etymology:
Sunday is traditionally recognized as the first day of the week in Christian contexts, often associated with rest and worship. The name "Sunday" is derived from Old English "Sunnandæg," which means "day of the sun." In many cultures, it is considered a day of rest and religious observance.

Biblical Significance:
Sunday holds particular significance for Christians as it commemorates the resurrection of Jesus Christ. According to the Gospels, Jesus rose from the dead on the first day of the week, which is Sunday. This event is central to Christian faith and is celebrated weekly in Sunday worship services.

Scriptural References:
The resurrection of Jesus on the first day of the week is documented in several passages. In the Gospel of Mark, it is written: "When the Sabbath was over, Mary Magdalene, Mary the mother of James, and Salome bought spices so they could go and anoint the body of Jesus. Very early on the first day of the week, just after sunrise, they went to the tomb" (Mark 16:1-2). Similarly, the Gospel of John states: "On the first day of the week, Mary Magdalene came to the tomb early, while it was still dark, and saw that the stone had been removed from the tomb" (John 20:1).

Early Church Practice:
The early Christians began to gather on Sundays to break bread and worship, as indicated in the Acts of the Apostles: "On the first day of the week, we came together to break bread. Paul spoke to the people and, because he intended to leave the next day, kept on talking until midnight" (Acts 20:7). This practice reflects the shift from the Jewish Sabbath (Saturday) to Sunday as the primary day of Christian worship.

Theological Implications:
Sunday worship is seen as a celebration of the new creation inaugurated by Christ's resurrection. It symbolizes the new covenant and the hope of eternal life. The Apostle Paul emphasizes the importance of the resurrection in 1 Corinthians 15: "But now Christ has been raised from the dead, the firstfruits of those who have fallen asleep" (1 Corinthians 15:20).

Historical Development:
By the second century, Sunday had become the established day of Christian worship. The early Church Fathers, such as Justin Martyr, wrote about the significance of Sunday gatherings. In his "First Apology," Justin Martyr describes Christians meeting on Sunday to read the Scriptures and partake in the Eucharist.

Cultural and Liturgical Observance:
In many Christian traditions, Sunday is observed as a day of rest and worship. It is a time for communal gathering, prayer, and reflection on the Scriptures. The observance of Sunday as a day of rest is rooted in the Fourth Commandment, which calls for a Sabbath rest, though Christians traditionally apply this principle to Sunday in honor of the resurrection.

Contemporary Practice:
Today, Sunday remains a central day for Christian worship across denominations. Churches hold services that include preaching, singing, prayer, and the sacraments. It is a day set apart for spiritual renewal and community fellowship, reflecting the joy and hope of the resurrection.Mark 2:28
Therefore the Son of man is Lord also of the sabbath.
