The first part of this elaborate work consists of a long preface, in which the author first retorts upon the Nonconformists the charge of encouraging Popery from the schism and divisions they had fomented, from their opposition to episcopal polity, which was a main bulwark against Popery, and from certain curious facts, according to which the Jesuits, it would seem, had insinuated themselves among the early Puritans, in order to excite them against the Church of England. He next mentions that he had been led to preach the sermon which had given rise to the controversy by a perusal of two works of Mr Baxter, in which the Church of England was assailed, and to which he had a right to offer a reply. He alludes, finally, to the five antagonists, Owen, Baxter, Howe, Alsop, and Barret, whom his present work was intended to answer.
