Biblical Answer

The question of whether Sunday is the Sabbath day is a complex one, with various interpretations and arguments presented by different groups. Some believe that Sunday has taken the place of the Old Testament Sabbath and therefore must be kept as the seventh day had been ordained by God. This view is often associated with Sabbatarianism, which holds that the church is in violation of the law of God by worshiping on Sunday rather than on Saturday. However, this view is not supported by the New Testament, which does not mention Sunday as the Sabbath. In fact, the New Testament consistently refers to the Sabbath as the seventh day of the week (Luke 4:31, Acts 20:7).

The early Christian church, on the other hand, worshipped on Sunday, which was known as the Lords Day. This was a day of celebration for the resurrection of Jesus, and it was considered a holy day, set apart for God. The church came together on Sunday for the preaching of the Word and the celebrating of the sacrament, and this practice was virtually universal in every city and village. The apostles themselves referred to Sunday as the day of the Lord, and they saw it as a day of worship and celebration. In this sense, Sunday can be seen as a fulfillment of the Sabbath principle, rather than a replacement for it.

In conclusion, while some groups may argue that Sunday is the Sabbath day, the evidence from the New Testament and the early Christian church suggests that this is not the case. Sunday was a day of celebration for the resurrection of Jesus, and it was considered a holy day, set apart for God. The church came together on Sunday for worship and celebration, and this practice was widely accepted in the early Christian church. Therefore, it is reasonable to conclude that Sunday is not the Sabbath day, but rather a day of celebration and worship in its own right.
