I case you missed me saying so, I observe the Sabbath. I put aside any labors and restrict my activities to keep it holy. Not that I'm into doing unholy things the rest of the week, but I'm extra strict during the Sabbath. And I make sure to pray and worship. So it's not like I'm anti-sabbath. So I have no reason to deny any New Testimement scripture saying Christians kept the Sabbath. If it's there. Now those verses in Acts you gave, are not telling me the disciples kept the Sabbath. I'm not arguing they didn't. I'm just saying I don't see those verses really saying they did. And the real question is, is there anything about the churches Paul wrote his letters to keeping the Sabbath or any instruction for them to do so? I'll go over those whole chapters in Acts to see if my mind is changed any. I'm perfectly open to having my mind changed regarding this.
Good for you MMXX that you have an interest in keeping the Sabbath. There should be no argument with you then on this topic. Why would you think that those verses shared with you are not about the early disciples or apostles keeping the Sabbath when they so as much verbatim in the scriptures? Those in Acts are only a few of many. For me this is pretty clear when you have scriptures after the death of Jesus saying....
Acts of the Apostles 13:14 [14], But when they departed from Perga, they came to Antioch in Pisidia, and went into the synagogue on the sabbath day, and sat down.
Note: Going to church on the Sabbath. There is no need to mention the Sabbath and Synagogue together if they were not keeping the Sabbath btw.
Acts of the Apostles 13:27 [27], For they that dwell at Jerusalem, and their rulers, because they knew him not, nor yet the voices of the prophets which are read every sabbath day, they have fulfilled them in condemning him.
Note: Reading from the old testament scriptures every Sabbath.
Acts of the Apostles 13:44 [44], And the next sabbath day came almost the whole city together to hear the word of God.
Note: Why could not the everyone come together the next day and why did they wait to hear the Word of God the next Sabbath if they were not keeping the Sabbath? Seems pretty clear here they were keeping the Sabbath right?
Acts of the Apostles 15:21 [21], For Moses of old time has in every city them that preach him, being read in the synagogues every sabbath day
Note: Seems pretty clear here that they were keeping the Sabbath
Acts of the Apostles 16:13, And on the sabbath we went out of the city by a river side, where prayer was wont to be made; and we sat down, and spoke to the women which resorted thither.
Note: Seems also pretty clear here that they were keeping the Sabbath
Acts of the Apostles 17:2, And Paul, as his custom was, went in to them, and three sabbath days reasoned with them out of the scriptures,
Note: It seems it was Paul's custom to keep the Sabbath just like Jesus (see Luke 4:16).
.................
Now I am not sure why you say that that disciples were not keeping the Sabbath when the scriptures above say that they are. Let's through in a few more and build on the above if it might be helpful.
Matthew 28:1 [1], In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulcher.
Note: The disciples were still keeping the Sabbath here according to God's 4th commandment and left Jesus in the tomb on the preparation evening (see Mark 15:42-47).
Matthew 24:20 [20], But pray you that your flight be not in the winter, neither on the sabbath day
Note: Jesus is speaking of the destruction of Jerusalem and the end of the world (see Matthew 24:1-3). This is an event well after the death and resurrection of Jesus and a sign of the end of the world. Jesus clearly here still expected the disciples to be keeping the Sabbath.
....................
All the above scriptures clearly show the disciples were keeping the Sabbath and were expected to be keeping the Sabbath of God's 4th commandment well after the death and resurrection of Jesus.
That's the impression I got.
I see. So no one ever said to you that unless you go to an SDA Church on the Sabbath your not obeying God's 4th commandment. Well that is good to know. What gave you that impression? I am happy that God is guiding to to keep the Sabbath and his commandments because you love him.
God bless.
