Henry Jessey also observed the seventh-day Sabbath, although he was somewhat reluctant to promulgate his views on the subject. However, in 1647 he argued that the seventh-day was "[Christ's] Sabbath which he blessed and sanctified. It has been suggested that he may have authored the anonymous "Moralitie of the Fourth Commandment" (1652). In his posthumous work, Miscellanea Sacra, or Diverse Necessary Truths (1665) Jessey asserted that believing Christians "should have respect to all the Ten Commandments of the Law." Jessey's biographer records that he kept the Sabbath in his own chamber, with only four or five more of the same mind after being convinced that the seventh day should be kept by Christians evangelically. Jessey's itinerary throughout western England contributed to the beginnings of several Sabbatarian groups.
