My view is that I have never observed any correlation between programming ability and religious inclination. However I have observed that most of us tend to believe that we have come to our current faiths for sound reasons, and we further believe that anyone who is sufficiently intelligent and wise will agree with our prejudices.
The main result that I have seen is that many people express astonishment upon finding out that prominent programmers whom they respect disagree with them about religious matters. A secondary result is that the distribution of programmers among different faiths roughly matches the expected distribution of intelligent and often educated people among those faiths. Which, given the strong presence of heavily Christianized countries on PM (for instance the USA), means that there are a lot of Christians here.
For the record I happen to be an atheist, though I am not very militant about it (unless you set out to convert me).
