The trajectory of the English controversy from 1712 involved at least ten writers. By summer 1714 the debate on "The Scripture Doctrine of the Trinity" had ramified, and provoked a formal complaint from the Lower House of Convocation: the Blasphemy Act 1697 still made it an offence for "any person, educated in or having made profession of the Christian religion, by writing, preaching, teaching or advised speaking, to deny the Holy Trinity". Clarke drew up an apologetic preface, and then gave explanations which satisfied the Upper House of Convocation. He had strong supporters among the bishops. Clarke promised not to preach or write on the topic. Arthur Ashley Sykes and John Jackson from then on acted as his proxies. Other main participants in the controversy were John Edwards, Francis Gastrell, James Knight who published with Bull's biographer Robert Nelson, Richard Mayo of Great Kimble (son of the nonconformist Richard Mayo), Stephen Nye, Edward Welchman and Edward Wells.
