The phrase the Lord’s day appears only once in Rev. 1:9, 10. Some Christians have pointed to Sunday as the Lord’s day but the meaning of Lord’s day should be determined by reference to Scripture rather than by popular tradition.
There are only eight verses in the Bible that mention Sunday but none of these verses show that Sunday is a sacred day. And there is no verse in the Scriptures that identifies Sunday with connection to the Lord.
The Bible recognizes that the seventh day Sabbath is the Lord’s special day. From the very beginning of time, God set it aside as holy “God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made” (Gen. 2:3).
And the Lord declared the seventh day to be the memorial of His act of creation: “Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the Lord your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day and hallowed it” (Ex. 20:11).
Why this prohibition of work on “the seventh day”? Because it is a “sabbath of the Lord.” In fact, the Lord called the seventh day “my holy day” (Isa. 58:13).
Jesus declared Himself to be, “Lord also of the sabbath” (Mark 2:28). After pointing to the purpose of the Sabbath (v. 27) Christ directs attention to its Author, and thus to His own right to determine how that purpose shall best be realized. Man has no right to tamper with the day of God’s choosing.
Thus, when the phrase “the Lord’s day” is interpreted in accordance with evidence prior to and contemporary with John’s time, it appears that there is only one day to which it can refer, and that is the seventh-day Sabbath.
