The Church of God claims that Yehoshua and his disciples kept the Sabbath even in the New Testament. However, this is an ignorant claim that does not know the prophecies of the Bible. According to the Mosaic Law, the earthly temple where the Sabbath sacrifice was made was created as a model and a shadow of the heavenly temple. So, if you look closely at the temple on earth, you will see that the Sabbath was not observed.

[Hebrews 8:5] But the tent where they serve is just a copy and a shadow of the real one in heaven. Before Moses made the tent, he was told, "Be sure to make it exactly like the pattern you were shown on the mountain!"

Then, where is the heavenly temple that the Bible testifies? The heavenly temple that the Bible testifies about is Joshua.

[John 2:21~22] But Jesus was talking about his body as a temple. And when he was raised from death, his disciples remembered what he had told them. Then they believed the Scriptures and the words of Jesus.

Therefore, if you study the temple system on earth well, you will be able to see with your own eyes what Yehoshua, who is the reality of the heavenly temple, will accomplish. If you look at the temple on this earth, there is a sacrifice for the sins of the people and a high priest who enters the Most Holy for the sins of the people once a year. But all of this was a prophecy of what Yehoshua would accomplish. Yehoshua, the reality of the sacrificial lamb, became the sacrifice on the cross and ascended to heaven as the high priest, fulfilling the prophecy that the high priest of the earthly temple would enter the Most Holy.

[John 1:29] The next day, John saw Jesus coming toward him and said: Here is the Lamb of God who takes away the sin of the world!

[Hebrews 9:11~12] Christ came as the high priest of the good things that are now here. He also went into a much better tent that wasn't made by humans and that doesn't belong to this world. Then Christ went once for all into the most holy place and freed us from sin forever. He did this by offering his own blood instead of the blood of goats and bulls

The high priest of the temple on earth imputed all the sins of the temple to the goats. And he sent a goat to a demon named Azazel who lived in the wilderness. After Joshua ascended to heaven, he cast out the devil from heaven to earth. This fulfilled the prophecy concerning the Day of Atonement. Also, the Holy Spirit came upon the body of the saints and established it as a temple in heaven. The fact that the saints who received the Holy Spirit became the temple fulfilled the prophecy of the Feast of Tabernacles. With this, all the sacrifices offered in the temple on earth ended. Therefore, there is no need to keep the sacrifice for the remission of sins.

[Hebrews 10:18] When sins are forgiven, there is no more need to offer sacrifices.

Because the Church of God does not know the temple system and the fulfillment of prophecy, they claim that if they kept the Sabbath in the Old Testament, they should keep the Sabbath in the New Testament as well. There is no evidence in the New Testament that Yehoshua and his disciples kept the Sabbath or the Day of Atonement. Yehoshua went into the synagogue on the Sabbath to preach the gospel to the Jews in it.

In the New Testament, as in the Old Testament, names such as the Sabbath and the Passover are mentioned. But this does not mean that the apostles kept the Sabbath or the Passover. In the society we live in today, various civilized tools such as clocks, calendars, and computers have been developed to make it easy to know the time and date.

However, at the time of the apostles' activities, it was difficult to arrange their activities in chronological order, so the records were organized around the festivals and anniversaries of the Jewish people. Therefore, the record of going to the synagogue to preach on the Sabbath, or the record of trying to arrive in Jerusalem before Pentecost, is quoted to record actions, not Sunday worship or Sabbath observance.

Therefore, there is no record of keeping the Sabbath or Sunday worship in the New Testament. All Old Testament sacrifices were abolished by Yehoshua's sacrifice on the cross.

In the Old Testament, the keeping of the Sabbath by slaughtering a lamb foreshadowed the sacrifice of Yehoshua, the substance of the sacrifice. Therefore, in the Old Testament, the keeping of the Sabbath by slaughtering a lamb, but in the New Testament, the sacrifice of Yehoshua brought many people into the rest that is heaven.
