Freud argued that religious behavior exhibits many similarities to neurosis, and that religious belief may be understood as a system combining repression of drives and substitutive symbolic wish-fulfillment. Freud continued to write of religion as symbolic wish-fulfillment even after his 1926 modification to the theory of neurosis and anxiety. When Freud's revised theory of neurosis is applied to religious behavior, religion could be judged psychologically as an anxiety-reducing behavior. The resulting psychoanalytic framework does not compel a negative view of religion but suggests a domain for positive interaction of psychoanalytic thinkers and theologians.
