SABBATH BECOMES THE LORD’S DAY
“…there is no commandment in the Ten Commandments that says the Israelites were to keep the seventh day of the week….What God really commanded through Moses was: ‘Six days you shall labor and do all your work, but the seventh day is the Sabbath of the LORD your God’ “ (Exodus 20:9-10) R. A. Torrey (ref#30, p154).
“first day of the week. A Jewish expression for Sunday, and similar to the phrase used in the Gospels to describe the day of the week on which Jesus rose from the dead (Matt 28:1; Mark 16:2; Luke 24:1; John 20:1). This shows that Christians gathered for worship on Sunday, not Saturday (cf Acts 20:7; Rev 1:10), in order to acknowledge the crucial importance of Christ’s resurrection” ESV Study Bible (ref#125, p2216, [1 Cor 16:2]).
“…the Jewish holy day was abolished; and as a thing necessary to retain decency, order, and peace in the church, another day was appointed for that purpose” John Calvin (ref#187).
“Christ having risen from the dead always met his disciples on this day. And afterwards, the apostles and the churches were accustomed to come together on this day, “to break bread,” that is to celebrate the Lord’s supper. And when the apostle wrote his first epistle to the Corinthians, it was already established as a custom, not only in the church of Corinth, but in the churches of Macedonia and Galatia, that their contributions for the poor, should be collected on this day. From the apostolical practice, we rightly infer the divine authority for this change. So generally was the first day of the week observed, in commemoration of Christ’s resurrection, and for the celebration of religious worship, that in the times of the apostles, it had obtained the significant denomination of the Lord’s Day” Archibald Alexander (ref#175).
So, to Christians the first day of the week, Sunday, is the official Lord’s Day.
