Rising to the challenge I threw out, Peter has responded with numerous citations. He is probably using a secondary source (I wish he would name the source) with a list of citations. He has given so many I cannot respond to all of them. I do work seven days a week (rabbis don’t rest on Shabbat and this rabbi doesn’t even get to rest on Sundays).
Peter’s assertion is that many early Christians kept the Sabbath and did not participate in Sunday worship. My position is that Sunday worship was a fixture in Christian communities by the early second century. I am the first to admit that evidence of universal Sunday worship in the New Testament is completely overblown. Acts 20:7 was on the first day of the week, meaning Saturday night until Sunday at sundown (only Jews had weeks in the first century, so first day of the week had to mean by Jewish reckoning which starts at sundown). Since the events surrounding Acts 20:7 took place late at night, this was a Saturday night meeting, not a Sunday meeting. I’m sorry, Christian friends who use Acts 20:7 as if God commanded Sunday worship, but history is not on your side. Neither, however, is history on Peter’s side.
I will list some of Peter’s most important citations and respond. My goal is to show that Sabbath observance was not prominent in early Christianity. I am not trying to argue that Sunday worship is commanded by God. I am trying to show that Jews and Gentiles were distinct in the early church, at least in the early centuries.
First, Peter cites early Jewish authors:
