The article is a monograph by Carrier; a more popularized version of his article in German Studies Review. FFRF merely published it.
Fair 'nuff.
I don't sprechen any deutsch, however.
BTW this would make a fascinating segue into pseudepigraphy and conformity of the Bible to the original texts over time, given that even in the enlightened 20th century we apparently couldn't get quotes right, and yet still manage to not throw the baby out with the bath about accepting sources. Tolkien's Tree and Leaf and On Fairy Stories contain good passages about the philosophical considerations therein.
Cheers!
