There are people in all walks of life and religious persuasions who have discomforting thoughts about what they believe - and sometimes they even verbalize them to others.
However, it is also clear that they are no where near ready to look more carefully at the discomforting thoughts.
Indeed, for many people, iin order to continue functioning in their belief system, they vent negatively every now and then about it. They get it off their chest - then go back to it.
The analogy to marriage is probably apt: You can complain to a trusted friend about how your spouse drives you nuts - but that is far from saying, "I am thinking of leaving the marriage".
It's great that your wife is verbalizing some of her misgivings about the behaviour she sees in the Hall - but hold your horses because this woman may well be scared off your eagerness to listen.
In fact, I'd suggest a low key acknowledgement of her sentiments ("Gee, honey, that sounds hard to put up with") and an intentional switc to a positive topic ("Is now a good time to show you my plans for our vacation in September?").
Pairing a low-key responses with a change of topic to something positve is a powerful reinforcer of taking action to get on with your life.
