While the translator was working from the ninth edition of 1885, a tenth edition had appeared during 1887, to which unfortunately his attention was not called until quite recently. The principal additions and alterations affecting Vol. II. occur in §§ 98, 108, 119, and 147. On the section dealing with Anabaptism, the important changes have been made in the text, so that § 147 precisely corresponds to its latest and most perfect form in the original. As the printing of the volume was then far advanced, it was impossible thus to deal with the earlier sections, but students will find references in the Table of Contents to the full translation in the Appendix of those passages where material alterations have been introduced. JOHN MACPHERSON. FINDHORN, _March, 1889_. INTRODUCTION. § 1. IDEA AND TASK OF CHURCH HISTORY. The Christian Church is to be defined as the one, many-branched communion, consisting of all those who confess that Jesus of Nazareth is the Christ who in the fulness of time appeared as the Saviour of the world. It is the Church’s special task to render the saving work of Christ increasingly fruitful for all nations and individuals, under all the varying conditions of life and stages of culture. It is the task of Church History to describe the course of development through which the Church as a whole, as well as its special departments and various institutions, has passed, from the time of its foundation down to our own day; to show what have been the Church’s advances and retrogressions, how it has been furthered and hindered; and to tell the story of its deterioration and renewal. § 2.
