2. OBJECT OF THE WORK. The writers of all the Essays have endeavoured to make them sufficiently exhaustive to render it unnecessary for the majority of readers to go further for information, and, at the same time, sufficiently suggestive of more recondite sources of Theological study, to help the student in following up his subjects. By means of a Table prefixed to the Dictionary, a regular course of such study may be carried out in its pages. 3. PRINCIPLES OF THE WORK. The Editor and his coadjutors have carefully avoided any party bias, and consequently the work cannot be said to be either “High Church,” “Low Church,” or “Broad Church.” The only bias of the Dictionary is that given by Revelation, History, Logic, and the literary idiosyncrasy of each particular contributor. But the Editor has not attempted to assist the circulation of the book by making it colourless on the pretence of impartiality. Errors are freely condemned, and truths are expressed as if they were worth expressing; but he believes that no terms of condemnation which may be used ever transgress the bounds of Christian courtesy. 4. PART OF A SERIES. The Dictionary of Theology is complete in itself, but it is also intended to form part of a Series, entitled, “A Summary of Theology,” of which the second volume, “A Dictionary of Sects, Heresies, and Schools of Thought,” is in the press. “_Taken as a whole the articles are the work of practised writers, and well informed and solid theologians.... We know no book of its size and bulk which supplies the information here given at all; far less which supplies it in an arrangement so accessible, with a completeness of information so thorough, and with an ability in the treatment of profound subjects so great. Dr. Hook’s most useful volume is a work of high calibre, but it is the work of a single mind. We have here a wider range of thought from a greater variety of sides. We have here also the work of men who evidently know what they write about and are somewhat more profound (to say the least), than the writers of the current Dictionaries of Sects and Heresies._”――GUARDIAN.
