His first sermon, delivered January 4, 1846, was founded on 1st Cor. 2: 2: "For I determined to know nothing among you save Jesus Christ, and him crucified,"--a text which was the key-note of his whole theologic harmony. In the plot of this sermon there are three simple divisions: 1. Why did St. Paul bring his labors and efforts to bear on this one point? Why would he know nothing else? 2. What is it to know Jesus Christ and him crucified? 3. The danger of mixing other things with the Gospel, thereby dividing and polluting the minds of the hearers. The reasons assigned under the first division are: 1. Christ is the only hope of a lost world, the only medium by which we can approach God. 2. He wished that his hearers should be rightly taught, that their faith might stand in the power of God, not in the wisdom of men. "To know Jesus Christ," he said, "is to understand his history, to know his doctrine, to have him in our experience, to know the power of his resurrection, which is eternal life." It is, however, impossible to form any adequate idea of a sermon of his from a plot, as he was so richly extemporaneous, and never committed to paper anything more than the guiding points of his discourse; the minutiæ were wholly in his mind. If the several hundred plots of sermons found amongst his papers were presented to the world, it would soon appear that only those who have heard him in the days of his strength could form any just idea of the discourses he gave, for his spoken language was infinitely more eloquent and free than his written, and there was so much that made up the total interest in his manner, voice, and expression, that cannot, by any known skill, be transferred to paper. Like the speaking of Whitfield and Henry Clay, the _occasion_ only was the true witness of his power. The written report, though it reads well, carries but little of the peculiar life-impress, the fine pathos, the delicate humor, the ready turn of thought, the quick imagination, and the falling tear of the listening auditor. It is only by _hearing_, we say, that Joseph Badger's pulpit abilities can be judged. Casting his eye over New England society, he pleaded the necessity of broader sympathy and union, of greater confidence between ministers and people, and for a giving up of local prejudices between the east and the west, as the cause of Christ is a unit over all the world. He extols the spirit and labors of Benjamin Taylor in the Bethel cause, at Providence, R. I., which served to send over the wide seas the pure principles of unsectarian religion; the same praise was bestowed on the efforts of Moses How, of New Bedford, whose labors for years in the seaman's cause, have been catholic in nature and efficient in result. In glancing at the generally low state of religious interest, whose causes he thought lay deeper than the lack of human science, he said:--
