Crosses To Bear

I’d like to ask everyone here (and over at my Blog, where I’ll mirror this post) for a little help. I’ve been having a discussion with my wife about the novel I’m writing. More exactly, about the title of the book, “Crosses To Bear”. I’ve chosen the title because of the underlying theme of the story, which involves living with guilt and living with burdens. The phrase, I think, conveys that in a nicely poetic way. My wife objects (we are both firm atheists) because she thinks the phrase has a strong religous meaning and that the audience will expect the book to have some sort of religous content. It won’t.

So I guess my question is, what do you think when you hear the title? Do you think it sounds preachy, would you assume the book had religous content, or would you just assume the title was metaphor?
