"So long as Christian preachers and writers are limited so much to human creeds and systems, or to stereotyped phrases of any kind, and avail themselves so little of the popular diction of literature and of common life, so long must they repel many whom they might convince and win." Dr. Porter, _President of Yale College_. 5. Then again: the divisions of the Church, and the uncharitable spirit in which points of difference between contending sects are discussed, and the disposition sometimes shown by religious disputants to impugn each other's motives, to call each other offensive names, and to consign each other to perdition, are occasions of stumbling to some. 6. And again: many advocates of Christianity, more zealous than wise, say more about the Bible and Christianity than is true, and attempt to prove points which do not admit of proof; and by their unguarded assertions, and their failures in argument, bring the truth itself into discredit. Others use unsound arguments in support of the truth, and when men discover the unsoundness of the arguments, they are led sometimes to suspect the soundness of the doctrine in behalf of which they are employed. The pious frauds of ancient and modern fanatics have proved a stumbling-block to thousands. Albert Barnes says, "There is no class of men that are so liable to rely on weak and inconclusive reasonings as preachers of the Gospel. Many a young man in a Theological Seminary is on the verge of infidelity from the nature of the reasoning employed by his instructor in defence of that which is true, and which might be well defended: and many a youth in our congregations is almost or quite a skeptic, not because he wishes to be so, but because that which is true is supported by such worthless arguments."
