For pastors looking for a solid, but less known treasure on the work of the pastor, I recommend you consider Thomas Murphy’s 1877 work, Pastoral Theology: The Pastor in the Various Duties of His Office. My dear friend, Jeremy Walker writes a very helpful summary of this important work:
“This 19th century Presbyterian divine opens with a most helpful definition of pastoral theology, and then goes on to develop it with regard to a pastor’s private person, his preparation and study, his pulpit labours, his personal parochial work, his wider responsibilities in the church, the progress of the church, the Sunday School, the benevolent work, the session and higher courts of the church (of course, depending on his ecclesiology), and his interdenominational relations. Few other volumes have the scope and depth of this one, as lots of sound, Scriptural sense is brought to bear on the various topics.”
