Until now he had not made a case for the change of the day. His book was about the Christian Sabbath, but what he argued for until now was the seventh-day Sabbath. To be sure, he made passing remarks on the change of the day. But he treats the change of the day in two chapters. The first one is dedicated to "the Apostolic Witness" where he examines the resurrection and the resurrection appearances as the prime reason for the change of the day, the day of Pentecost (Acts 2:1), the gathering of the Church on the first day to break bread and have Paul preached to them (Acts 20:7), the gathering of alms on the first day (1Cor 16:1-2) and finally, the Lord's Day (Rev 1:10). In my opinion, he makes a good case for the change of the day from these passages and also from his treatment of the abiding Sabbath from Hebrews 4:9.
Then he moves to the post-apostolic testimony to the Lord's Day. He notes that often the word Sabbath was retrained for the Jewish Sabbath and was not frequently used for Sunday. Rather, from the earliest times, the expression "the Lord's Day" was used for the first day of the week on which Christ rose.
Finally, he moves on in the last part (3) to teach us how we should observe the Sabbath. He is careful in his suggestions and what He may say and deduce from God's Word. His desire is not to bind consciences where God has not bound them, but carefully give guidelines and suggestions.
Overall, I very much enjoyed reading this book and I used it a lot in my own study for the 1689 Baptist Confession's chapter 22 on the Sabbath (sections 7-8). It is detailed, it is biblical and it is written in a loving and respectful tone. What more can we expect? Get it and read it already!
