Exodus International is the "largest Christian referral and information ministry" in the ex-gay movement, according to its Web site. Its monthly newsletters, annual conferences, speaking engagements and Web services offer encouragement and help for "unwanted homosexuality." Exodus does not believe individuals are born gay. It believes homosexual feelings are a byproduct of a person's upbringing and unnatural desires. With counseling, prayer, and other support, individuals can be changed through "the transforming power of the Lord Jesus Christ."
Founded in 1976, it is an interdenominational organization which, according to its own description, "has grown to include over 120 local ministries in the USA and Canada" and is "linked with other Exodus world regions outside of North America, totaling over 150 ministries in 17 countries." Exodus promotes a "system of support" comprising a church, a therapist and a support group.
