“Now when Jesus was risen early the first day of the week, he appeared first to Mary Magdalene, out of whom he had cast seven devils.”- Mark 16:9
There is a notable reason why Christians have worshipped on the first day of the week since its very beginning: it is the day that Jesus rose from the grave. What better way to celebrate the atonement for sin, the abrogation of the law service, the promise of eternal life and the ascension of Jesus Christ back to the Father, than to meet and worship with other believers on the very same day that Jesus declared His victory?
This fact, the Sunday worship of the Christian Church, may be proved both historically, as well as scripturally. You may trace the footsteps of the flock by Christians themselves or other unbiased writers and find them worshipping on the first day of the week from the very day that Christ rose from the grave. About two-thousand years of unbroken faithfulness by God’s chosen people is the greatest testimony to the promise of Jesus that anyone could ask for: “Upon this rock will I build my church, and the gates of hell shall not prevail against it.” The death of the Christian Church has been announced for two millenniums and Christ still reins faithful among His people!
For the historical record, you may read great historical books like, “Jones Church History”, or even the monumental Schaff’s history of the Christian Church and find this basic, fundamental practice of God’s people to be on the first day of the week.
Biblically, we never find in Scripture that even the converted Jews worshipped in a Christian assembly on any other day than Sunday. On the very day that Jesus rose from the grave, which was the first day of the week, the disciples assembled together, and Jesus appeared in the midst of them and by His gracious presence and divine instructions, showed His approval of their thus meeting together as well as encouraged their continuance of it. On this same day He appeared to them again at night (John 20:19). It has been proven by many learned writers that Pentecost occurred on this great day commemorating the day of Christ’s resurrection. The Apostle Paul gave orders to the church at Corinth to make a collection for the poor saints on the first day of the week, (1 Corinthians 16:1,2), because this was obviously the day in which they habitually met. This first day of the week is the day that John had reference to when he said, “I was in the Spirit the Lord’s day”.(Revelation 1:10). For those who would be sticklers and say that people were breaking the forth commandment and go to hell for it if they were to worship on any other day we find the early Christians so excited about their Savior that they were “daily in thee temple, and in every house, they ceased not to teach and preach Jesus Christ.”(Acts 5:42). They worshipped and met daily! Thus, any day is a day to worship Jesus. But the day set aside for the gathering of the saints in a Church capacity is especially the first day of the week, Sunday, proven by divine revelation. Be there!
