Question 16
Which day did Paul (who authored most of the New Testament) keep?
Bible
Acts 17:2
"Paul, as his manner was, went in unto them and three Sabbath days reasoned with them out to the scriptures."
Acts 18:4
"And he reasoned in the synagogue every Sabbath, and persuaded Jews and Greeks."
Answer
Paul’s custom (or manner) was the same as Jesus' custom; he was in the synagogues teaching on every Sabbath day. There, he taught both Jews and non Jews.
