The Sabbath is surely the teachings of the early church, But nowadays many churches doesn't keep the sabbath. The worship day is surely the Sabbath. Only World Mission society church of God keep the Sabbath which were restored by the Second Coming Christ Ahnsahnghong.

In the time of Moses, God commanded His people, in the fourth commandment of the Ten Commandments, to "remember the Sabbath day by keeping it holy." God explained the purpose for keeping the Sabbath by saying, "In six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy" (Ex. 20:11).

God gave His people the Sabbath as the sign by which God would recognize them as His people (Ezek. 20:11-17; Isa. 56:1-7).

Since the first day of the week is Sunday, what day is the seventh day? Through The Bible, we can confirm that the Sabbath day is Saturday.

The Sabbath day in the Old Testament was called "the Sabbath of Jehovah" (Ex. 31:13; Ezek. 20:12), while the Sabbath day in the New Testament was called "the Sabbath of Jesus" (Matt. 12:8; Luke 6:5).

Testament times, the apostles kept the Sabbath day by worshiping God in spirit and in truth, following Jesus Christ's example.

Jesus kept the Sabbath as His custom. (Luke 4:16)

The apostles kept the Sabbath day as their custom(Acts 17:2)

As time passed, the faith of the Christians weakened, and they began to accept the customs of the sun-god worshipers. During this turn-over, they even began to rest and to worship on the first day of the week [Sunday]. In A.D. 321, Constantine, a Roman emperor, decreed an edict.

The Church of God was established on the foundation of the apostles who followed the teachings of Jesus Christ, and it has not changed since its inception. The true Church follows the laws which Jesus and the apostles observed.

The saints, who will be saved on the last day, the day of God's judgment, are those who follow in Jesus' footsteps. The Sabbath day, one of Christ's footmarks, is a very precious commandment of God. (Mat 7:21)
