——>Scripture never mentions any Sabbath (Saturday) gatherings by believers for fellowship or worship.
Sorry Dude, but you and “GotQuestions.org” are wrong. But, I guess I would naturally expect that, seeing as how you hate anything associated with God’s commandments, especially the 4th. Not a chance on this earth that any of the apostles would ever keep Sunday over a commandment of God. But you would.

It is also clear from the book of Acts, that Paul kept only the Sabbath day in Corinth, and not Sunday:
Acts 18:1 After these things Paul departed from Athens, and came to Corinth;
Acts 18:4 And he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.
Acts 18:11 And he continued there a year and six months, teaching the word of God among them.
That’s 72 Sabbaths that Paul preached in Corinth. There can be no question that Paul raised up a Sabbath keeping church in Corinth, a church that knew nothing of observing Sunday as a holy day. So, while many will point to 1 Corinthians 16:2 in the light of Tradition, and say that it refers to passing the collection plate during a Sunday service, in context, that is simply not indicated by the text.
Sorry, dude, but Paul would have had to go to the synagogues when the people met. He wasn’t endorsing the sabbath as being on Saturday.
