From the Prince of Preachers:
Natural humor may possibly be consecrated and made to wear the yoke of Christ, but he who apes it is no true man. If you find us a man who has any object in this world in what he says but the glory of God, and the winning of souls, he is the man who is out of center, and into his secret may we never come. And furthermore, if you discover a preacher who is indelicate, and causes the cheek of modesty to tingle, let him be cast out of the pulpit, and the door locked against him. We have known men of the Slop-dash order who would have been nothing if they had not been outrageous, and of these it may be said that they were worse than nothing when they followed their own style. There was nothing in their absurdities to excuse them, for they were not carried away by zeal, nor did the excellence of their matter make up for the ridiculousness of their manner. Of such men we will neither be defender nor judge.
