The word fiction comes from a Latin verb meaning “to shape, fashion, feign.” That is what fiction does, and in many ways it is what faith does too You fashion your story, as you fashion your faith, out of the great hodgepodge of your life-the things that have happened to you and the things you have dreamed of happening. They are the raw material of both. Then, if you’re a writer like me, you try less to impose a shape on the hodgepodge than to see what shape emerges from it, is hidden in it. You try to sense what direction it is moving in. You listen to it. You avoid forcing your characters to march too steadily to the drumbeat of your artistic purpose, but leave them some measure of real freedom to be themselves. If minor characters show signs of becoming major characters, you at least give them a shot at it because in the world of fiction it may take many pages before you find out who the major characters really are just as in the real world it may take you many years to find out that the stranger you talked to for half an hour once in a railway station may have done more to point you to where your true homeland lies than your closest friend or your psychiatrist.
