Question 17
Which day did the Gentile (non Jewish) believers keep?
Bible
Acts 13:42
"And when the Jews were gone out of the synagogue, the Gentiles asked that these words might be preached to them the next Sabbath."
Answer
The Gentile believers asked Paul to return and preach to them the next Sabbath. If they were keeping Sunday, the Bible would have said that the Gentiles asked Paul to return and preach to them "tomorrow".
