James Fowler outlines 6 stages of faith development:
1) Undifferentiated faith in infancy based on trust between caregiver and infant.
2) Intuitive-projective faith in preschoolers who use imagination to explain the unknown and are influenced by parents' faith.
3) Mythic-literal faith in elementary schoolers who rely on stories and rules from authority figures taken literally.
4) Synthetic-conventional faith in adolescents who choose beliefs and values based on social norms rather than reflection.
5) Individuative-reflective faith in young adults who critically reflect on beliefs and values and resolve tensions between perspectives.
