Gibson, the great Chief-Justice of Pennsylvania, once said to certain skeptical friends of his: "Give Christianity a common-law trial; submit the evidence _pro_ and _con_ to an impartial jury under the direction of a competent court, and the verdict will assuredly be in its favor." This deliverance, coming from the most illustrious judge of his time, not at all given to expressions of sentimental piety, and quite incapable of speaking on any subject for mere effect, staggered the unbelief of those who heard it. I did not know him then, except by his great reputation for ability and integrity, but my thoughts were strongly influenced by his authority, and I learned to set a still higher value upon all his opinions, when, in after life, I was honored with his close and intimate friendship. Let Christianity have a trial on Mr. Ingersoll's indictment, and give us a decision _secundum allegata et probata_. I will confine myself strictly to the record; that is to say, I will meet the accusations contained in this paper, and not those made elsewhere by him or others. His first specification against Christianity is the belief of its disciples "that there is a personal God, the creator of the material universe." If God made the world it was a most stupendous miracle, and all miracles, according to Mr. Ingersoll's idea are "the children of mendacity." To admit the one great miracle of creation would be an admission that other miracles are at least probable, and that would ruin his whole case. But you cannot catch the leviathan of atheism with a hook. The universe, he says, is natural--it came into being of its own accord; it made its own laws at the start, and afterward improved itself considerably by spontaneous evolution. It would be a mere waste of time and space to enumerate the proofs which show that the universe was created by a pre-existent and self-conscious Being, of power and wisdom to us inconceivable. Conviction of the fact (miraculous though it be) forces itself on every one whose mental faculties are healthy and tolerably well balanced. The notion that all things owe their origin and their harmonious arrangement to the fortuitous concurrence of atoms is a kind of lunacy which very few men in these days are afflicted with. I hope I may safely assume it as certain that all, or nearly all, who read this page will have sense and reason enough to see for themselves that the plan of the universe could not have been designed without a Designer or executed without a Maker.
