So called from the Greek which signifies co-operation. Hence this name was given to those in the sixteenth century who denied that God was the sole agent in the conversion of sinful man, and affirmed that man co-operated with divine grace in the accomplishment of this salutary purpose.
Charles Buck (1771-1815) was an English Independent minister, best known for the publication of his “Theological Dictionary”. According to the “Dictionary of National Biography”, a Particular Baptist minister named John C. Ryland (1723-1792) assisted Buck by writing many of the articles for the aforementioned publication. One may conclude, based not only Buck’s admiration for his friend Ryland, but also on the entries in his Theological Dictionary, that he stood head and shoulders with the High-Calvinists of his day.
