Since the idea of an original sin is completely incompatible with Objectivist premises, imo trying to 'marry' Christianity to the philosophy of Ayn Rand doesn't work.
I was born a and raised a Roman Catholic but no longer belong to this church.
I have never been very religious (even as kid, I had certain doubts about elements of the catholic dogma). This has made it easier for me to finally leave not only Catholicism, but all other attachment to the Christian faith behind me.
Over the years, I have become an agnostic currently leaning more the the atheist side of the fence.
The Jesus character is a good example to demonstrate what can happen in patchworking: let's disconnect, for illustration purposes, from the Jesus figure the idea of original sin, the idea of his resurrection from the dead, the idea of his being sacrificed to assuage the wrath of god ... taken to the extreme, one might as well then drop the whole religous context that goes with the Jesus figure. Jesus will be 'humanized down' to such a degree that he resembles more a psychological guru than a godsend.
Thank you for your thoughtful comment. I will respond shortly in a PM as I am busy with my kids.
