The Worship of the English Puritans by Horton Davies really valuable book for gaining historical perspective on the American Presbyterian scene. (I will note for the record that I don’t believe there is an objective definition for “puritan” and I wish historians would stop using it and instead speak of “English Calvinists” or “dissenters” or use some other label that actually designates a particular group by shared characteristics. But it is still a good book.) What is especially helpful is chapter 4: “Puritan Worship and the Continental Reformed Churches.”
Davies points out that it was “clearly the intention to bring English worship into line with Reformed practice” (p. 35). Furthermore, the Puritans would “appeal to the continental Reformed Churches for precedents.” Even the Separatists would do this.
Oddly, however, one John Durel, a Reformed pastor of a congregation in Savoy, France published an entire book arguing that the Anglicans were closer to the Reformed Churches than the Pruitans. It was entitled, A View of the government and Publick Worship of God in the Reformed Churches beyond the Sea (London 1662). On page 14 of that work, according to Davies, he wrote that the views held by the Westminster Assembly regarding the continental Reformed churches were, “mere Chimeras and Ideas; which, like the Utopia of Sir Thomas More, never existed but in their brain.”
Davies goes on in the chapter to examine Durel’s claims and evaluate them. As I have time I’ll post more about what he says on various practices and structures that the Puritans were advocating as “Reformed.”
