Description: Drawn from Christian sources from before the middle of the third century AD, the ancient evidence is unanimous that although there were a few slight differences as to how weekends should be observed, one thing was certain: The main day of the week for early Christians to gather and worship was not the seventh-day Saturday Sabbath, but Sunday, which they sometimes called ""the first day,"" ""the eighth day,"" or ""the Lord's Day."" This work considers (1) whether the Lord's Day replaces the Sabbath, (2) whether the Sabbath was abolished, (3) whether Sabbath-keeping is forbidden, (4) whether Jesus and Christians before AD 250 considered the Sabbath unimportant, (5) how the Lord's Day is to be observed, (6) whether the Roman Catholic Church changed the Sabbath to Sunday, (7) a critique of the sources and authorities on which Sabbatarians rely in advancing their contentions, and (8) where readers can find translations of these sources for themselves.
