VJack over at Atheist Revolution recently asked, “Could one arrive at Christianity through rational means?“
That actually depends on how you define Christianity.
The select few who call themselves Christians without subscribing to core modern Christian beliefs (the divinity of Jesus, virgin birth, triune God-head, vicarious redemption), taking the Bible as a collection of myths and advice, could have be Christians for rational reasons. Following the Jesus character’s advice regarding how to treat one’s neighbor is a worthy goal. I don’t see any reason why this “Christianity” would be necessarily irrational.
However, anyone who believes in the same God most Christians do — a miracle-working slacker who loves and damns everyone — has a logically impossible belief-set. Heck, I used those core beliefs to prove such a god would be evil. None of it makes any sense. That kind of religion can never be rational.
