Lincoln speech on the Bible?

[ELCore]

'It seems to me that nothing short of infinite wisdom could by any possibility have devised and given to man this excellent and perfect moral code. It is suited to men in all conditions of life, and includes all the duties they owe to their Creator, to themselves, and to their fellow-men.'"

This quote has always seemed a bit 'Lincolnesque' to me, but made under different circumstances, perhaps during his White House years? (possibly when presented a Bible or meeting with leaders of a religious group)
I had never questioned it's authenticity, so thanks for sharing Fehrenbacher's "C" rating on the quote and circumstances.

It sounds a lot like this:

In regard to this Great Book, I have but to say, it is the best gift God has given to man. All the good the Saviour gave to the world was communicated through this book. But for it we could not know right from wrong. All things most desirable for man’s welfare, here and hereafter, are to be found portrayed in it.
