God commanded us to remember the Sabbath day by keeping it holy (Exodus 20:8.) And He even designated it as a sign between God and God’s people.

You must observe my Sabbaths. This [Sabbath] will be a sign between me and you for the generations to come, so you may know that I am the LORD, who makes you holy… (Exodus 31:13)

We can understand how important the Sabbath day is. Without keeping the Sabbath, we cannot know God who makes us holy. Then, which day is the Sabbath: Sunday or Saturday? The above movie reveals that the Sabbath is Saturday, not Sunday.

Some say that they worship on Sunday because the Lord’s Day is Sunday.

On the Lord’s Day I was in the Spirit, and I heard… (Revelation 1:10)

Then, the Lord’s Day is Sunday? In the time of the Old Testament, the Lord is Jehovah. In Exodus 31:13, the Lord said, “You must keep my Sabbaths.” So, the Lord’s Day in the Old Testament was the Sabbath or Saturday. Then, how about in the time of the New Testament? In the time of the New Testament, the Lord is Jesus.

For the Son of Man [Jesus] is Lord of the Sabbath. (Matthew 12:8)

It’s obvious that the Lord’s Day is the Sabbath or Saturday. (However, many people misunderstand that the Lord’s Day is Sunday, but the biblical Lord’s Day is the Sabbath or Saturday.) Jesus kept the Sabbath as His custom (Luke 4:16) and the Apostle Paul also kept it as his custom (Acts 17:2, 18:4.) Even, a Catholic book wrote as follows:

“But you may read the Bible from Genesis to Revelation, and you will not find a single line authorizing the sanctification of Sunday. The Scriptures enforce the religious observance of Saturday…” (The Faith of Our Father, pp. 72-73)

If we do not keep God’s feasts such as the Sabbath day and the Passover, we do not know God who makes us holy. Sunday service was introduced to the churches in 321 AD, long after the Ascension of Jesus and the death of the Apostles and Disciples. Therefore, it’s natural that the record about Sunday is not found in the Bible.

Some insist that the Sabbath was changed to Sunday after Christ’s Crucifixion. However, the Apostle Paul, who appeared after Jesus’ Crucifixion, also kept the Sabbath as his custom (Acts 17:2.) So their argument is neither biblical nor true.

Sunday service is a mere man-made rule, not a feast of God. What is God’s will: Sunday service or the Sabbath day? If we follow man-made rules, our worship will be in vain.

They worship me in vain; their teachings are but rules taught by men. (Matthew 15:9)

Without keeping the Sabbath day according to the teaching Jesus, we cannot be saved. The World Mission Society Church of God (WMSCOG) observes the Sabbath day and the Passover according to the teachings of the Bible. In addition, the Church of God believes in Christ Ahnsahnghong who restored all truth including the Sabbath and the Passover and fulfilled all prophecies of the Bible.
