The minister should preach as if he felt that although the congregation own the church, and have bought the pews, they have not bought him. His soul is worth no more than any other man's, but it is all he has, and he cannot be expected to sell it for a salary. The terms are by no means equal. If a parishioner does not like the preaching, he can go elsewhere and get another pew, but the preacher cannot get another soul.
