It is a very good book although as SD Adventist I don't agree with its following thesis “Sunday is a new day of worship that was chosen to commemorate the unique salvation history, the historical event of the death and resurrection of Christ.” Nevertheless, this book makes some excellent true statements. It admits that the Sabbath cannot apply to any other day than the seventh day. It admits that the Sabbath has a redemptive significance. It admits that the early Christians in the New Testament kept the Sabbath (seventh day), including the Gentiles. Why then the authors do not accept SDA teaching on the Sabbath? Look for pastor Jack Sequeira on youtube preaching on Sabbath as a memorial of salvation by faith.
