I've always believed you go to literature to find the shared human experience, not the categorized human experience.
Most of the characters I write with don't think an awful lot about their faith. They're not always questioning the church or feeling confined by the church or rebelling against the church.
As a writer, you have to put yourself in service to the character, get behind their eyes by delineating the world where the character develops. You have to listen to the character and see him inside his certain world to know what conclusions he would draw.
I'm more interested in character than events. I've observed that about myself as a writer. I find events, even the most dramatic sort, not to be such fertile ground.
Character is primary. What happens as far as plot and events is not as intriguing to me as what's happening inside this particular person.
Our task as fiction writers isn't just to report something that didn't really happen. We have to give what we write a sense of reality. The tool of our tradition is language.
