Actually, no. George Washington died because his doctors bled him to death with leeches. The history of medicine is much worse than the history of Christianity. You pick a doctor carefully, you should pick a pastor carefully. Both can do you a lot of good or a lot of harm.

But you missed my point. In the case of your particular chosen doctor, you rely on the fact that he has studied hard and trained well and therefore your decision to accept what he prescribes does not involve going back and reviewing whether there is absolute proof available. You don't demand such evidence to save your physical life, why do you demand it to save your eternal life?
