In "The Market Day of the Soul," James T. Dennison examines the question of the supreme Christian holy day, the Sabbath. He shows how the Sabbath emerged from the imprecision of the sixteenth century to become a celebrated cause in pre-Revolutionary England. Finally, he demonstrates the triumph of the Puritan Sabbath during the Revolution, a triumph that continued to make the English Sabbath distinctive into the nineteenth century. In the course of this investigation, Dennison shows that the Puritan view of the Lord’s Day became the dominate view - both theologically and practically - by the latter half of the seventeenth century, in spite of challenges it faced from the "medieval" position of the Court party and the Seventh-day Sabbatarians.
