The Unitarian books which Mr. Lincoln read cursorily, the books by Parker and Channing, must have assisted him in this, that they gave assurance that there were forward-looking men who believed in God and in human freedom as he did, and who were quite as far from holding the teaching which he had been taught to call orthodox as he was, yet who were not infidels, but counted themselves friends of God and disciples of Jesus Christ. Herndon asserts that Lincoln habitually spoke in his presence in terms of denial of the supernatural birth of Jesus. On this point I have seen but one bit of documentary evidence, and that of unique interest, in two words written in a book that once belonged to Lincoln. The book is entitled _Exercises in the Syntax of the Greek Language_, by Rev. William Nielson, D.D., and contains two appendixes by Prof. Charles Anthon, noted as a Greek scholar and the author of a Greek Grammar and other textbooks. It was published by T. & J. Swords in New York, in 1825. At the bottom of page 34 is a sentence, shortened and modified from John 16:27, and printed in parallel Greek and English,-- "Ye have loved me, and have believed that I came forth from God." The words "from God" are erased with pen, and the words, "from nature" substituted, apparently in the handwriting of Mr. Lincoln. This, if its genuineness be established, would appear to be conclusive that at the time Lincoln owned this book he denied the supernatural birth of Jesus. The book was formerly a part of the noted collection of Mr. John E. Burton, procured by him from the collection of Dr. J. B. English, and was retained by Mr. Burton with other unique items when his large collection was broken up some years ago. I was privileged to examine the book by A. C. McClurg & Co., in April, 1919; the book being then and possibly still owned by them.
