SIR--In regard to your inquiry, just received, of what I heard Lincoln say about a charge of infidelity made against him when a candidate for Congress in 1847, or '48, it was this. I was present and heard Josiah Grady ask Lincoln a question or two regarding a charge made against Lincoln of being an infidel, and Lincoln unqualifiedly denied the charge of infidelity, and said, in addition, his parents were Baptists, and brought him up in the belief of the Christian religion; and he believed in the Christian religion as much as anyone, but was sorry to say he had or made no pretensions to religion himself. I can't give his exact words, but would make oath anywhere that he positively denied the charge made against him of infidelity. That was the first time I ever heard of the charge of infidelity against Lincoln. Grady did not say that he would not vote for Lincoln if he was an infidel; but my understanding from Grady was, that he would not vote for Lincoln if he was an infidel, and Grady did, as I suppose, vote for him. I understood him that he should. Respectfully, THOMAS MOSTILLER. MENARD COUNTY, ILL. The next evidence I shall offer is that of Isaac Cogdal, an intimate friend of Lincoln's from the time Lincoln came to Salem, Menard County, to the time he left for Washington City, and I will let Cogdal speak for himself. STATEMENT OF ISAAC COGDAL April 10, 1874. B. F. IRWIN: Yours received making inquiries about what I heard Lincoln say about his religious belief, is this, as near as I can tell it and recollect. I think it was in 1859, I was in Lincoln's office in Springfield, and I had a curiosity to know his opinions or belief religiously; and I called on him for his faith in the presence of W. H. Herndon. At least Herndon was in the office at the time. Lincoln expressed himself in about these words: He did not nor could not believe in the endless punishment of any one of the human race. He understood punishment for sin to be a Bible doctrine; that the punishment was parental in its object, aim, and design, and intended for the good of the offender; hence it must cease when justice is satisfied. He added that all that was lost by the transgression of Adam was made good by the atonement: all that was lost by the fall was made good by the sacrifice, and he added this remark, that punishment being a "provision of the gospel system, he was not sure but the world would be better off if a little more punishment was preached by our ministers, and not so much pardon of sin." I then, in reply, told Mr. Lincoln he was a sound Universalist, and would advise him to say but little about his belief, as it was an unpopular doctrine, though I fully agreed with him in sentiment. Lincoln replied that he never took any part in the argument or discussion of theological questions. Much more was said, but the above are the ideas as advanced by Lincoln there. Respectfully yours, ISAAC COGDAL.
