Retrospect: the First Christian Century 287 Copyright, 1915, by John Gresham Machen INTRODUCTION The general purpose of this course of lessons has been set forth in the introduction to the Student's Text Book. There is a tendency in the modern Church to neglect the study of Bible history. Such neglect will inevitably result in a loss of power. The gospel is a record of something that has happened, and uncertainty about the gospel is fatal weakness. Furthermore the historical study of the apostolic age--that age when divine revelation established the great principles of the Church's life--is the best corrective for a thousand vagaries. Much can be learned from modern pedagogy; but after all what is absolutely fundamental, both for teacher and for student, is an orderly acquaintance with the Bible facts. The Teacher's Manual, therefore, is intended not merely to offer suggestions as to methods of teaching, but primarily to supplement the teacher's knowledge. A teacher who knows only what he actually imparts to the class is inevitably dull. The true teacher brings forth out of his treasure things new and old. The sections in the Teacher's Manual, since they are intended to be supplementary, should not be read until after careful attention has been paid to the corresponding sections in the Student's Text Book. Moreover, both sections together are of course in themselves insufficient. They should be supplemented by other reading. Suggestions about reading have been put at the end of every lesson. Here, however, a few general remarks may be made.
