Masson, the great authority on this subject, gives in the following pages a clear and comprehensive account of the religious situation in Great Britain at the time, of the composition of the assembly, and of its labors during the five years and more of its continuance. At the time of the meeting of the Westminster Assembly there was a tradition in the Puritan mind of England of two varieties of opinions as to the form of church government or discipline that should be substituted for episcopacy. In the first place there was a tradition of the system of views known as Presbyterianism. From the beginning of Elizabeth's reign, if not earlier, there had been Nonconformists who held that some form of the consistorial model which Calvin had set up in Geneva, and which Knox enlarged for Scotland, was the best for England, too. Thus Fuller, who dates the use of the term "Puritans," as a nickname for the English Nonconformists generally, from the year 1564, and who goes on to say that within a few years after that date the chief of those to whom that term was first applied were either dead or very aged, adds: "Behold, another generation of active and zealous Nonconformists succeeded them: of these Coleman, Button, Halingham, and Benson (whose Christian names I cannot recover) were the chief; inveighing against the established church discipline, accounting everything from Rome that was not from Geneva, endeavoring in all things to conform the government of the English Church to the Presbyterian Reformation." Actually, in 1572, Fuller proceeds to tell us, a presbytery, the first in England, was set up at Wandsworth in Surrey; _i.e._, in that year a certain number of ministers of the Church of England organized themselves privately, without reference to bishops or other authorities, into a kind of presbyterial consistory, or classical court, for the management of the church business of their neighborhood. The heads of this Presbyterian movement, which gradually extended itself to London, were Mr. Field, lecturer at Wandsworth, Mr. Smith of Mitcham, Mr. Crane of Roehampton, Messrs. Wilcox, Standen, Jackson, Bonham, Saintloe, Travers, Charke, Barber, Gardiner, Crook, and Egerton; with whom were associated a good many laymen. A summary of their views on the subject of church government was drawn out in Latin, under the title _Disciplina Ecclesiæ sacra ex Dei Verbo descripta_, and, though it had to be printed at Geneva, became so well known that, according to Fuller, "_Secundum usum Wandsworth_ was as much honored by some as _secundum usum Sarum_ by others."
