I tried doing a search, but the 3 letters in Sin prevented that.
Where in the bible does it say that humans have original sin?
Original Sin in Scripture, from the Catholic Encyclopedia (1913 ed.).
Ah, whether you are religous or not the Catholic Encyclopedia is one of the most fascinating books ever written.
All that is dear to Christianity is built upon original sin. There is a story about a preacher and cousin of Ethan Allen, telling Ethan that without original sin there was no need for Christianity. Ethan thought about it so long that the cousin asked him if he agreed. Ethan replied that after long consideration, he did agree. There was no need for Christianity.
