As a religious studies expert, I am well-versed in the history and traditions of various faiths, including Christianity. The practice of holding church services on Sundays has a rich and complex history that is deeply rooted in both religious and cultural contexts. Let's delve into the origins and reasons behind this tradition.

The observance of Sunday as a day of worship and rest in Christianity can be traced back to the early days of the faith. According to the New Testament, Jesus was resurrected on a Sunday, which is why it is often referred to as the "Lord's Day." This event is central to Christian belief, marking the triumph of life over death and the fulfillment of messianic prophecies. The resurrection is celebrated every Sunday, serving as a weekly reminder of Christ's victory and the promise of eternal life for believers.

In the 2nd century AD, as Christianity began to spread and develop its own distinct practices separate from Judaism, some Christians started to observe Sunday as a special day. This was the day of the week on which Jesus had risen from the dead, and it was also the day on which the Holy Spirit had come to the apostles during the event known as Pentecost. The significance of these events cannot be overstated, as they form the foundation of Christian theology and practice.

The early Christians were influenced by the Jewish Sabbath, a day of rest and worship observed from Friday sunset to Saturday sunset. However, as Christianity evolved, the focus shifted from the Sabbath to Sunday. A Church Father, Eusebius, noted that for Christians, "the Sabbath had been transferred to Sunday." This transition reflects a theological shift as well as a practical adaptation to the predominantly non-Jewish Christian community.

The shift to Sunday also had social and cultural implications. In the Roman Empire, Sunday was already a day of rest, known as the dies solis or "day of the sun." By holding services on this day, Christians were able to gather without the same restrictions that might have been placed on them during the workweek. Over time, Sunday became the standard day for Christian worship, a tradition that has continued to the present day.

Furthermore, the observance of Sunday as a day of worship has been codified in Christian doctrine and canon law. The Council of Laodicea, held in the 4th century, specifically prohibited Christians from attending the Jewish Sabbath and instead mandated that they rest on the Lord's Day, which is Sunday.

In conclusion, the tradition of church on Sundays is a multifaceted practice that encompasses theological significance, historical development, and social adaptation. It is a day that commemorates the most pivotal events in Christian history and serves as a weekly opportunity for Christians to come together in worship and community.
