Did the Disciples Worship on Sunday?

Many churches try and use Acts:7-11 to prove that Sabbath has changed from the 7th day to Sunday, the 1st day:

Acts:7-11 On the first day of the week, when we were gathered together to break bread, Paul began talking to them, intending to leave the next day, and he prolonged his message until midnight. There were many lamps in the upstairs room where we were gathered together. And there was a young man named Eutychus sitting on the window sill, sinking into a deep sleep; and as Paul kept on talking, Eutychus was overcome by sleep and fell down from the third floor, and was picked up dead. But Paul went down and fell upon him, and after embracing him, he said, “Do not be troubled, for he is still alive.” When Paul had gone back up and had broken the bread and eaten, he talked with them a long while until daybreak, and then left. They took away the boy alive, and were greatly comforted.”

As you can see, those verses have nothing to do with worship, all it says is that they met, ate and listened to Paul speak, but no mention of worship, just guys getting together to have a last meal with Paul before he leaves

The fact is, Jesus and his disciples always worshiped on the Sabbath.

Mark 1:21 “Then they went into Capernaum, and immediately on the Sabbath He entered the synagogue and taught”

Mark 6:2 “When the Sabbath had come, He began to teach in the synagogue. And many hearing Him were astonished, saying, ‘Where did this Man get these things? And what wisdom is this which is given to Him, that such mighty works are performed by His hands!'”

Luke 4:16 “So He came to Nazareth, where He had been brought up. And as His custom was, He went into the synagogue on the Sabbath day, and stood up to read”

Luke 6:6 “Now it happened on another Sabbath, also, that He entered the synagogue and taught. And a man was there whose right hand was withered”

Even after Jesus dies and rose, the disciples continued following the example of Jesus worshiping on the Sabbath, as we can clearly see in the book of Acts:

Acts 13:14 “When they departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the Sabbath day and sat down”

Acts 13:42 “When the Jews went out of the synagogue, the Gentiles begged that these words might be preached to them the next Sabbath”

Acts 18:4 “He reasoned in the synagogue every Sabbath, and persuaded both Jews and Greeks”.

Was the 7th day Sabbath just for the Jewish people?

The 7th day was set apart, made Holy in the very beginning, Genesis 2:1-3 Thus the heavens and the earth, and all the host of them, were finished. And on the seventh day God ended His work which He had done, and He rested on the seventh day from all His work which He had done. Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.

Many try and say that the 7th day Sabbath was made for the Jews, but as you can see the 7th day was made Holy long before the Jewish nation was ever established.
