Lord's Day. Revelation 1:10. From the times of the apostles, the first day of the week has been kept sacred by Christians in commemoration of the resurrection of Christ, and it is invariably designated as the Lord's day by the fathers of the primitive church up to the time of the edict of Constantine, when the name Sunday became common. "On the first day of the week when the disciples came together to break bread, Paul preached unto them." Acts 20:7. His charge "concerning the collection for the saints" to the church in Corinth is, "Upon the first day of the week let every one of you lay by him in store, as God hath prospered him." 1 Corinthians 16:1-2. John commences the Revelation saying: "I was in the Spirit on the Lord's day." Revelation 1:10. The Lord's day, as the Sabbath, reminds us of the finished work of creation and redemption. See Sabbath.
