Peter Bulkeley

Peter Bulkeley's Gospel Covenant Or the Covenant of Grace Opened deals with the Mosaic covenant in chapter 8.  Like most Puritans and Continental Reformed theologians, Bulkeley sees it as essentially a covenant of grace.  On page 62 he deals with the objection that "the covenant of works was delivered to the children of Israel at Mt. Sinai."  Though he admits that though God did reveal to them in the law "the knowledge of the covenant of works," it "was not delivered unto that people for this end, to stand between God and them for a covenant of works." 
 
Later Bulkeley distinguishes between the law "considered absolutely and by itself, as containing a covenant of works," and the law "dependently, and with respect to the covenant of grace" (63).  It was only in the latter sense that it was delivered to Israel at Mt. Sinai, "As antecedent to [the covenant of grace], to prepare them for Christ and the covenant of grace; and also subsequent to it, to teach them how to walk and please God, when they were entred into a new covenant with him" (64).
 
Bulkeley then gives eight arguments to prove that the Mosaic covenant was a covenant of grace, and then answers several common objections against this position.  He concludes it typical Puritan fashion by explaining the various "uses" of this important doctrine.
