6. Lastly. Of all the difficulties and controversies which have arisen in these our Churches since the time of the Reformation, there is none that has not had its origin in this doctrine, or that has not, at least, been mixed with it. What I have here said will be found true, if we bring to our recollection the controversies which existed at Leyden in the affair of Koolhaes, at Gouda in that of Herman Herberts, at Horn with respect to Cornelius Wiggerston, and at Mendenblich in the affair of Tako Sybrants. This consideration was not among the last of those motives which induced me to give my most diligent attention to this head of doctrine, and endeavour to prevent our Churches from suffering any detriment from it; because, from it, the Papists have derived much of their increase. While all pious teachers ought most heartily to desire the destruction of Popery, as they would that of the kingdom of Antichrist, they ought with the greatest zeal, to engage in the attempt, and as far as it is within their power, to make the most efficient preparations for its overthrow.
