Have you seen this essay by Samuel Miller on the Sabbath?

Samuel Miller was perhaps the J. I. Packer of the early 19th century - not only was he a prolific author in his own right, but he also wrote introductory essays to the works of other authors. At least, he wrote a 1833 introductory essay to John Holmes Agnew's Manual on the Christian Sabbath. Miller's essay deserves to be more well-known - which is why Log College Press exists!
