The author, after defining the idea and object of a visible church, makes an elaborate effort to trace to its sources and in its course the development of religious opinion in England previous to 1640. He marks the rise of Barrowism, Brownism, of the Johnsonists, the Separatists, the Presbyterians, the early Independents, the two parties of Baptists, and the Friends, or Quakers. Some of the views, habits, and principles adopted by these parties he traces in their connection with the Mennonites on the Continent. He distinguishes, as far as possible, the various shades of opinion, the introduction of new points of controversy or discussion, the individualisms, extravagancies, eccentricities, and erratic excesses of individuals or parties, and he keeps distinct the two main currents of the development, as they favored or rejected the connection of civil and ecclesiastical authority. He draws the line distinctly between the Episcopalians and Presbyterians, on the one side, as according in favoring a state church and a national establishment, and the original ideas gradually developed into positive principles of individuals and societies among the Separatists, which involved the complete separation of the administration of religion from the civil power. The central subject of Mr. Barclay’s volume is the early history of the Friends, or Quakers. Two chief points are specially dealt with: First, many of the distinctive principles in their teaching and conduct which have been generally regarded as original with them are traced as in full recognition by other parties previous to the preaching of George Fox. Second, the author presents many facts, new, or in a new light, which disclose how earnest were the efforts of the early Friends for a very careful and even elaborate inner organization and discipline of their membership, after the manner of a visible Church,—the appointment and oversight of a qualified ministry, the sending out of authorized missionaries, and the inquisition into the private affairs, the home life, habits, and business of members, carried out into very minute and annoying details. He reveals to us the embarrassments met by them in deciding upon the question of “birthright membership.” Manuscript documents, records, minute-books, etc., preserved in many places where the early Friends had their meetings, are found very communicative.[462]
