Mano Singham writes:
During the discussion on atheists coming out, someone made a very enlightening remark. He said that he recalled seeing the late Madalyn Murray O’Hair, the militant atheist who was responsible for the case that resulted in school-sponsored prayer being outlawed from public schools, on TV talk shows. He said she would love to get the audience all worked up and hissing at her with her provocative statements. Then she would tell them “You hate me because I am the embodiment of all your doubts.”
That makes sense. All religions depend on faith, the willful act of belief in something that cannot be discerned. Faith implies belief in the absence of, and counter to, evidence. Such an effort necessarily involves the suppression of doubt. When a person of one religion encounters someone from another, it is relatively easy to think that yours is the ‘right’ faith and the other person’s is the ‘wrong’ one. The other person is not challenging the very act of faith, but just the details of that faith.
The greater challenge to faith is not a competing faith, but doubt. When persons of faith encounter an atheist, that brings them face to face with their own doubts and that can be much more disconcerting.
This is very similar to something George Smith wrote:
In Christianity doubt stands opposed not to certainty per se, but to faith. To have faith, in a religious context, is to have absolute confidence in God and to trust his revelations unconditionally. Thus, for the Christian to be uncertain of a divine revelation is bad enough, but to doubt that revelation is incomparably worse, because the latter implies a readiness to criticize that the former does not. ... In short, for the Christian to doubt the truth of a purported revelation is potentially to challenge the authority of the infallible God in whom she believes. It is therefore religious doubt, not atheistic disbelief, that constitutes the greatest threat to orthodox beliefs, because doubt threatens to undermine a belief system from within.
I wonder if this is also one reason why so many Christians insist that atheism if a faith? If, as Singham writes, faith is less threatening than doubt, then “atheism as a faith” can be dismissed more readily than “atheism as a challenge, a question, and a doubt.” I don’t think it likely that many, if any, Christians actually think about the issue in these terms, but this doesn’t mean that the connection isn’t being made unconsciously.
