This article describes the use of Fowler's (1981) faith development theory (FDT) in counseling. FDT is a stage model of spiritual and religious development that allows counselors to identify both adaptive qualities and potential encumbrances in spiritual or religious expression. FDT offers a nonsectarian model of spiritual growth that permits assessment of spiritual development apart from the specific contents of various faith traditions. This article summarizes Fowler's faith stages and demonstrates their clinical utility through composite vignettes.
