There are definitely risks in trying to revise what you have been taught, but there are also risks in trying to hold on to what has come to seem unbelievable. A mature faith will be one in which you examine and reject teachings that you have good reasons to think are mistaken, but also discover what it is vital to hold on to. As the book explains, the task of rethinking faith claims is not a purely individual undertaking; your own reflection needs to occur with an awareness that in the larger Christian community others have engaged in the same kind of project of reflecting on the faith and have reached conclusions that are worth considering. In the book I use my own experience to illustrate how you can reject what is unacceptable, but also work toward a faith that you can affirm wholeheartedly.
