I'm married to one, but I think that even using the word 'moderate' to describe her is too strong. A better way to describe her would be someone that is unwilling to denounce the residual layer of Catholicism that was implanted in her brain as a child. In fact, the closest she ever gets to discussing religion is saying 'God bless you' when someone sneezes.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
