What is the main conflict in Rome Sweet Home: Our Journey to Catholicism by Scott Hahn?

Kim grows up interested in serving God and little changes for most of her life throughout the book. She wants to be a pastor but then decides she wants to be a pastor's wife. She marries a pastor, has children and is living the good life as she sees it. Her life is rocked when Scott becomes interested in Roman Catholicism. Her dreams and community connections are shaken to their core because Catholicism will potentially detach her from her family and friends and alter her conception of her faith that she has held for all of her life.
