History of the Sabbath
The seventh day was consecrated by God as a Sabbath in the beginning of the earth (see Genesis 2:2–3). Since earliest times, the tradition of a sacred seventh day has been preserved among various peoples of the earth. God renewed a commandment concerning this day to the Israelites, saying, “Remember the sabbath day, to keep it holy” (Exodus 20:8). Keeping the Sabbath day was also a sign that the Israelites were His covenant people (see Exodus 31:12–13, 16; Isaiah 56:1–8; Jeremiah 17:19–27).
The Lord’s Day
Why was the Sabbath changed from the seventh day to the first day?
Until His Resurrection, Jesus Christ and His disciples honored the seventh day as the Sabbath. After His Resurrection, Sunday was held sacred as the Lord’s day in remembrance of His Resurrection on that day (see Acts 20:7; 1 Corinthians 16:2).
From that time on, His followers observed the first day of the week as their Sabbath. In both cases there were six days of labor and one for rest and devotion.
The Lord has given us a direct commandment in these days that we too should honor Sunday, the Lord’s day, as our Sabbath (see DC 59:12).
