The following Lectures have a peculiar history. They were originally delivered to the Baptist Church in Caldwell, N. J., in the ordinary course of pastoral labors in that place, and were not then intended for the press. At the urgent request of those who heard them, the author was induced to give them to the public. They were delivered from meager notes, and from these, as his "copy," the author, himself a practical printer, set up the types of the first edition. As much of the matter was thus extemporized, at the "case," the entire book was never written. Several editions were printed during the few following years, and the work was widely circulated through the country, and seems to have given a new phase to the baptismal controversy, by directing attention to the GREAT PRINCIPLES which underlie the action of the Baptist denomination.With the earnest prayer that the present edition may be as useful, at least, as previous ones, in leading Christians of every name to the knowledge and practice of Bible truth, the work is commended to the blessing of God, and the candid consideration of the reader.
