In his book 1981 book Stages of Faith , James W. Fowler developed a theory of six stages that people go through as their faith matures based on the Piaget stages and Kohlberg stages. The basic theory can be applied, not only to those in traditional faiths, but those who follow alternative spiritualities or secular worldviews as well. In his 1987 book A Different Drum, M. Scott Peck offered a simplified version focusing only on the four most common stages. See also: Erikson stages

Stage Description Simplified version by M. Scott Peck

Stage 1 Intuitive-Projective This is the stage of preschool children in which fantasy and reality often get mixed together. However, during this stage, our most basic ideas about God are usually picked up from our parents and/or society. I. Chaotic-Antisocial People stuck at this stage are usually self-centered and often find themselves in trouble due to their unprincipled living. If they do end up converting to the next stage, it often occurs in a very dramatic way.

Stage 2 Mythic-Literal When children become school-age, they start understanding the world in more logical ways. They generally accept the stories told to them by their faith community but tend to understand them in very literal ways. [A few people remain in this stage through adulthood.]

Stage 3 Synthetic-Conventional Most people move on to this stage as teenagers. At this point, their life has grown to include several different social circles and there is a need to pull it all together. When this happens, a person usually adopts some sort of all-encompassing belief system. However, at this stage, people tend to have a hard time seeing outside their box and don't recognize that they are "inside" a belief system. At this stage, authority is usually placed in individuals or groups that represent one's beliefs. [This is the stage in which many people remain.] II. Formal-Institutional At this stage people rely on some sort of institution (such as a church) to give them stability. They become attached to the forms of their religion and get extremely upset when these are called into question.

Stage 4 Individuative-Reflective This is the tough stage, often begun in young adulthood, when people start seeing outside the box and realizing that there are other "boxes". They begin to critically examine their beliefs on their own and often become disillusioned with their former faith. Ironically, the Stage 3 people usually think that Stage 4 people have become "backsliders" when in reality they have actually moved forward. III. Skeptic-Individual Those who break out of the previous stage usually do so when they start seriously questioning things on their own. A lot of the time, this stage ends up being very non-religious and some people stay in it permanently

Stage 5 Conjunctive Faith It is rare for people to reach this stage before mid-life. This is the point when people begin to realize the limits of logic and start to accept the paradoxes in life. They begin to see life as a mystery and often return to sacred stories and symbols but this time without being stuck in a theological box. IV. Mystical-Communal People who reach this stage start to realize that there is truth to be found in both the previous two stages and that life can be paradoxical and full of mystery. Emphasis is placed more on community than on individual concerns.
