While there is a general agreement among the writers as to principles, the greatest freedom as to treatment is allowed to writers in this series. The volumes, for example, are not of the same length. Volume II, which deals with the formative period of the Church, is, not unnaturally, longer in proportion than the others. To Volume VI, which deals with the Reformation, has been allotted a similar extension. The authors, again, use their own discretion in such matters as footnotes and lists of authorities. But the aim of the series, which each writer sets before him, is to tell, clearly and accurately, the story of the Church, as a divine institution with a continuous life.
