The Gospel Preacher (volume 1) is a collection of twenty full-text sermons by Benjamin Franklin, published in 1869. These sermons average 20 pages each. This is not the Benjamin Franklin associated with the founding of the United States, but his great-great-great nephew who was named after him. This man, in most writings, is referred to as “Elder Benjamin Franklin.” Many preachers in the 1800s were called “elder,” just like today, many preachers are called “pastor.”
Definitions of Doctrine is a basic doctrines book in three volumes. Vol 1 has 26 chapters dealing with the doctrine of God. Vol. 2 has 27 chapters on Sin, Salvation, and Service. Volume three has 27 chapters on the Church.
This is a very large and somewhat complicated work by Alger (Universalist) on issues of the existence and destiny of the soul. Note that this work may contain arguments against the existence of hell. I would not recommend it for most Christians.
