The function of the pastor-teacher is to provide the congregation with scholarly teaching and apologetics. They are supported by their local congregation. As well, the pastor-teacher selects those educated in the Scriptures, to read and teach (as an extension of his office). The Pastor-teachers lead the prayer times. Depending on the size of the congregation, there may be more than one pastor-teacher. While the bishop functions as the pastor-teacher in the church, not every pastor-teacher would be the bishop.
