The Third Commandment says, “Remember the Sabbath day, and keep it holy.” The Sabbath, properly speaking, is Saturday, the seventh day of the week. In this sense, all of us [unless you happen to be Seventh Day Adventist] violate the commandment. So, why do we? Why do Christians, generally, worship and set aside Sunday as their holy day?
It all goes back to Jesus and the Resurrection. All four Gospels point to the first day of the week [Sunday] as the day of Jesus’s Resurrection. [See: Matthew 28:1, Mark 16:1, Luke 24:1, John 20:1] Each Sunday’s worship is to find its life in the resurrected life of Jesus. The center point of the church’s [and our own] life is the Resurrection of Our Lord. Jesus’s Resurrection changed the way understand time, both past, present and future.
The time of Sunday worship seems to be variable. While our general experience with going to Sunday worship tends to be sometime in the morning, there is good evidence that Christians have also worshipped at other times of the day. There is good speculation that in many New Testament communities, Sunday worship was in the evening and included dinner.
