We Haven't Even Gotten Into Lincoln's Faith:

But the term "theistic rationalist" may aptly describe it. From a new article:

(RNS) On the eve of the 150th anniversary of the start of the Civil War, a long-lost letter has surfaced that describes President Abraham Lincoln's belief in God.

The Raab Collection of Philadelphia plans to sell a recently discovered letter written in 1866 by William Herndon, a Springfield, Ill., lawyer and Lincoln confidant.

"Mr. Lincoln's religion is too well known to me to allow of even a shadow of a doubt; he is or was a Theist & a Rationalist, denying all extraordinary -- supernatural inspiration or revelation," wrote Herndon of the nation's 16th president.
