“Mr. Lincoln was never a member of any church, nor did he believe in the divinity of Christ, or the inspiration of the Scriptures in the sense understood by evangelical Christians" from: Lamon, W: Life of Abraham Lincoln, page 486. James R.Osgood and Company, 1872. What is your source for the claim Lamon said Lincoln was a Christian?
The only other evidence you submit is anecdotal recollections of conversations the declarants claimed to have had with Lincoln.
You will have to do better than that before I believe a man guilty of numerous war crimes and constitutional abuses was a Christian.
