When Thomas Lincoln removed to Illinois he united with the Christian church commonly called "Campbellites," and in that faith he died.
Abraham Lincoln's belief was clear and fixed so far as it went, but he rejected important dogmas which are considered essential to salvation by some of the evangelistic denominations. "Whenever any church will inscribe over its altar as a qualification for membership the Saviour's statement of the substance of the law and Gospel, 'Thou shall love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and thy neighbour as thyself,' that church will I join with all my heart and soul."
He was an habitual reader of the Bible. He was more familiar with its contents than most clergymen, and considered it the highest example of literature in existence as well as the highest code of morals. His study of the Bible and familiarity with its pages are shown in his literary style and frequent quotations. In 1864 he wrote his old friend, Joshua Speed, "I am profitably engaged reading the Bible. Take all of this book upon reason that you can and the balance upon faith and you will live and die a better man."
He had no sympathy with theologians. He frequently declared that it was blasphemy for a preacher to "twist the words of Christ around so as to sustain his own doctrine," and often remarked that "the more a man knew of theology the farther he got away from the true spirit of Christ."
"John," he one day said to a friend, "it depends a great deal how you state a case. When Daniel Webster did it, it was half argument. Now, you take the subject of predestination, for example. You may state it one way and you cannot make much out of it; you state it another and it seems quite reasonable."
When he was a young man at New Salem in 1834 Thomas Paine's "Age of Reason" and Volney's "Ruines" made a great impression upon him, and he prepared a review of these books, which it is supposed he intended to read before a literary society that had been organized in the neighborhood. His friend, Samuel Hill, with his old-fashioned notions of atheism, got hold of the manuscript and burned it. Lincoln was quite indignant at the time, but afterwards admitted that Hill had done him a service. This incident has often been cited as evidence that Lincoln was an agnostic, just as other incidents in his life have been used to prove that he was a spiritualist, and still others that he was a Freemason; but he was none of them. He commended Masonry, but never joined that order; his inquisitive mind led him to investigate certain spiritualistic phenomena, and his essay at New Salem was nothing more than a presentation of the views of two famous unbelievers without personal endorsement.
Like Napoleon, Wellington, Bismarck, and other famous men, Lincoln was very superstitious. That peculiarity appeared frequently during his life. Even to the very day of his death, as related in Chapter VII., he told his Cabinet and General Grant of a dream which he was accustomed to have before important events in the war. A curious incident is related in his own language:
"A very singular occurrence took place the day I was nominated at Chicago, four years ago, of which I am reminded to-night. In the afternoon of the day, returning home from down town, I went upstairs to Mrs. Lincoln's reading-room. Feeling somewhat tired, I lay down upon a couch in the room, directly opposite a bureau, upon which was a looking-glass. As I reclined, my eye fell upon the glass, and I saw distinctly two images of myself, exactly alike, except that one was a little paler than the other. I arose, and lay down again with the same result. It made me quite uncomfortable for a few moments, but, some friends coming in, the matter passed out of my mind. The next day, while walking on the street, I was suddenly reminded of the circumstance, and the disagreeable sensation produced by it returned. I had never seen anything of the kind before, and did not know what to make of it. I determined to go home and place myself in the same position, and if the same effect was produced, I would make up my mind that it was the natural result of some principle of refraction of optics which I did not understand, and dismiss it. I tried the experiment, with a like result; and, as I had said to myself, accounting for it on some principle unknown to me, it ceased to trouble me. But some time ago I tried to produce the same effect here by arranging a glass and couch in the same position, without success."
He did not say, at this time, that either he or Mrs. Lincoln attached any significance to the phenomenon, but it is known that Mrs. Lincoln regarded it as a sign that the President would be re-elected.
President Lincoln once invited a famous medium to display his alleged supernatural powers at the White House, several members of the Cabinet being present. For the first half-hour the demonstrations were of a physical character. At length rappings were heard beneath the President's feet, and the medium stated that an Indian desired to communicate with him.
