Ehh, beyond that Lincoln loved to quote from the Bible, we don't know much except that his vague anti-organized religion rhetoric stopped suddenly shortly after his entry into politics.
I meant "group of people" in the loosest possible sense. Mainly that Lincoln did not go to church, as did many people during that period of time (on the borderline of the Second Great Awakening, which was, of course, in full mode by the time of Lincoln's ascension to politics), but he still considered himself a Christian and read the Bible (if only for quotes, who knows).
