Westminster Shorter Catechism Question for the Week
Q.59. Which day of the week has God designated as the Sabbath?
A. From the beginning of the world until the resurrection of Christ God established the seventh day of the week as the Sabbath. From that time until the end of the world the first day of the week is the Christian Sabbath.
The concept of celebrating the Sabbath on Saturday is so firmly established, there must have been something dramatic to change the celebration to Sunday. That dramatic event was the resurrection of Christ. Actually, the fact that the day of worship changed from Saturday to Sunday is one of the proofs of the resurrection.
On the first day of the week, when we were gathered together to break bread [share the Lord's Supper also called communion], Paul talked with them, intending to depart on the next day, and he prolonged his speech until midnight.
9 I, John, your brother and partner in the tribulation and the kingdom and the patient endurance that are in Jesus, was on the island called Patmos on account of the word of God and the testimony of Jesus. 10 I was in the Spirit on the Lord’s day, and I heard behind me a loud voice like a trumpet 11 saying, “Write what you see in a book and send it to the seven churches, to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea.”
