I would say that she's in a situation of not owning her reasons, and thus she likes to exert the implications of what these other, older people think and recommend (raising our kids Catholic, me trying until my death bed to believe, etc.) but when pressed on any specific point, she's unable to speak to the logic or implications because they are not really her arguments/thoughts.
Reminds me of a family friend of mine, the wife of the most religious scientist I know, an astrophysicist who has more books on Christianity than astrophysics. I've discussed religion with her a few times, and it seems that her primary motivation for believing is a conviction that people like her husband know what they're talking about.
If you haven't already, you might want to bring up the fact that other religions and denominations also have their intelligent, experienced supporters, and taking it as given that the supporters of any one religion know what they're talking about means concluding that the supporters of every other religion don't. You have to be able to step outside the faith to give everyone their fair shakes. If she's motivated more by her stake in the community, it might move her somewhat to consider that other communities believe differently, and go through a similar song and dance with different doctrines at stake. It might help get her thinking "there are other communities I could be part of if I didn't believe what I believe now."
I then asked what she would say if I told her that archaeologists have never found any evidence to support anything like the Exodus portrayed in the OT and that some doubt that a figure named "Moses" even existed.
In cases like this, I think it's better to find out what she expects, ideally something you don't know about or something she doesn't suspect you already know about, so that rather than justifying the data post hoc, she can take notice of what she would anticipate given her beliefs being true, and then find out whether reality agrees with that.
Last night we were talking and she brought up how the OT prophecies came true in Jesus. I asked for an example and she said something vague about Moses and Jesus. I said, "Do you mean that like Moses led the Israelites out of slavery from their bondage in Egypt, Jesus leads us out of slavery and bondage to the evil one and sin?" She agreed that this was what she meant.
Since I was exposed to many believers' views on Christianity well before I started researching the religion myself, I was quite surprised to find out what the old testament messianic prophesies actually entail. Not only did Jesus never fulfill most of them even by generous interpretations, he never claimed in life that he was going to fulfill many of them. The doctrine of the Second Coming actually arose out of attempts to square the scriptural requirements for the messiah with all the things Jesus didn't accomplish; the messiah has to do them, and Jesus didn't, so it must be that he's going to do them when he comes back.
If you bring this up with your wife, you should wait for a time when she's more receptive to it. It won't make much difference for her to find out if she hasn't already made herself aware that she expects otherwise.
I've discussed religion with her a few times, and it seems that her primary motivation for believing is a conviction that people like her husband know what they're talking about.
True, and since widespread refutation of theism isn't happening (or accepted), there are always Swinburnes, Plantingas, Kreefts, and WLCs to point to.
It might help get her thinking "there are other communities I could be part of if I didn't believe what I believe now."
I actually brought this up last night. She could conceive of it being possible that had she been a...
Edit/Update: Wow, not even a day later this has had quite the number of comments. Hopefully more will come in, but I'd like to thank those who have contributed so far. The suggestions that I think I'm really going to run with are:
I'd like to "honorable mention" a suggestion begun by James Miller that I could just pretend to believe for the sake of preserving relationships and social satisfaction. I see some merit to this but think it might have been based on thinking that my closer/est friends/wife didn't already know (they do). The comment made for some interesting comments, but I think I'd just feel like a phony and even more miserable if I were to really implement this suggestion for any extended period of time.
---
This issue has been negatively affecting me for quite some time and for lack of clear solutions on my own and knowing that some here have traversed the same stream, I thought I'd ask for help and suggestions. If you're interested, some background information about my story exists here, here, and here.
Background
For the sake of having at least some information here, the brief synopsis is like so:
Yes, that last conclusion had some more contributing to it, but for the sake of brevity, just accept that this was my stance. Following the outburst and relatively minor consequence, it was almost like my "second chance" holy life was just waiting there to be lived. I had a renewed sense of purpose and ran with it.
I built the next seven or so years of my life completely around god and my Catholic faith. Much of this is covered in the link above to my blog, where I've written down a rough draft to my story. In short, I married who I did because of god/religion, went to the college I did because there was an extremely active Catholic outreach group connected to it, and a couple years ago even professed a lifelong commitment to a lay association of Catholic families who pledge themselves to live their lives with a common vision, attend bi-weekly events, complete [theological] education courses [taught by members of the same community], attend a couple of retreats together each year, and more.
Then I, literally out of the blue, a question popped into my head; I wondered whether other historians had written about Jesus. I googled the question various ways and was surprised/disappointed to find out that none had in the manner I expected. The rest is history. It's about 15mos later and I'm a non-believer.
What now?
I'm posting as trying to navigate the social implications of my deconversion has been quite difficult. My close friends were some of the first I informed, probably within a month. This community, however, is probably ~300 members strong. I know a lot of acquaintances via our [former] common religious beliefs.
I find myself quite fearful when I see these individuals. I'm afraid something will come up that will be awkward or that I'll be in a large-group setting and somehow a lot of individuals will find out about my non-belief at once in an "untactful" manner. Some of this is due to a sense of friendship -- if someone learns something more serious about my life, I'd prefer that it be from me.
A bit more irrationally, I fear how their opinions about me will be affected. I already think some think I'm "broken" somehow. In fact, I had a member of my former men's group tell me I was "crazy" (verbatim) when I told him it may very well be possible that some or all of the gospels were made up. I felt talked to like a small child by my men's group leader as a result of my non-belief. Heck, some might think I'm possessed by a demon. My wife and I turned our mattress a couple weeks ago and there was some sort of religious trinket (maybe a scapular?) under my side of the mattress on the box spring. She said someone suggested that it might be helpful...
I also find myself balancing between insecurity and anger. I'm insecure because I just plain wish I was more secure in my non-belief... yet I find myself looking back over my shoulder wondering if I've made a wrong turn in my reasoning, if I've simply pendulum-swung over to the opposite extreme as a result of my initial doubts, or if there's some remaining book that would answer my questions. I read mostly atheistic material, though I have read a couple books per the requests of those close to me. I've also been adding books suggested to my list. I admit, though, it's been far more rewarding to do woodworking than analyze the latest solution of the problem of evil. I guess I'd just say that it's been hard to "fully let go" and just walk away from my past belief, hence the insecurity.
On the other hand, I am easily angered in certain situations, perhaps resulting out of feeling insulted and addressed by hypocrites. Those around me want to know if I've read x, y, and z books by a, b, and c apologists. They want to remind me of how hard this is on my wife (who's still a believer). They would like to make the case for my wife raising our children as believers due to the incredible gravity of the future of their souls. And this all from, as far as I can tell, the comfort of ignorance of the theological/apologetical landscape. Some are fairly educated, but the average individual who would like to critique my path could not provide anything in the way of even a summary of the various topics and arguments involved when trying to answer the question of god's likelihood. That's frustrating.
What I'm looking for
For my own part, I'd say that I need to do more work brainstorming through possible conversation paths, and especially identifying why this all bothers me so much. Or perhaps the latter is simply obvious -- I don't have any close friends anymore who think I'm rationally justified in not believing in their deity. In writing that out, I suppose that is a pretty heavy social hit to take. Even after having these friends for seven years, I'm more "at ease" talking with those at Minnesota Atheists meetups that I've only been attending about 1-2x/month for less than a year.
This ended up far longer than I expected. I knew that was a potential issue when I started it and tried revising some bits and pieces, but I think I'll leave it. For one, this is the discussion area and I'm not necessary trying to present a well-thought out proposal; this is a request for input, ideas, support, and especially suggestions from those who may have been through something similar.
Also, I have to say that writing this out is slightly like talking to the close friend I don't really have. Much of my "real feelings" about this whole issue are kept inside because I simply don't want to hurt those around me by expressing them or bringing it up. My relationships go far better when god just doesn't come up at all, or at least stays to "meta-discussion" like, "How's this all going for your wife and you?" vs. "Here's this new book you should read which will definitely prove you are wrong." As a result, my outlets for bouncing these questions and difficulties around are a bit limited.
