Galt and Christ

I have to wonder how much Rand was using the story of Christ as a foil to make her point. Galt openly says that he does not believe in original sin, and in the book he is the only one free of it. Galt is perfect and without sin. Then, he is betrayed (accidently) by one he loves. They attempt to kill (crucify) him, but in this case salvation depends on him NOT dying - since heaven is to be found here on earth.
