We can be absolutely sure that the Jerusalem Church kept the Sabbath.
James and the others had favor with the people — even priests obeyed the faith (Acts 2:47; 6:7). This would have been utterly impossible if the Church had been meeting on Sunday (or any other day) and breaking the Sabbath.
If that had been the case, it would have been mentioned as the major accusation against, and problem for, the Church. The Church was indeed persecuted by the religious leaders of the day, but not for Sabbath-breaking.
The Jews from Palestine were really after Paul. They wanted to find something against him. He was constantly under attack. But he was never even accused of breaking the Sabbath, as was Jesus. This proves that Paul never even appeared to break it, much less did he actually teach against it.
