Professional training for therapists working with religious or spiritual issues doesn’t really exist and there are no requirements, at least for psychologists.
With spiritual and religious abuse, the social context is completely different from any other recovery situation. In the case of religious abuse, a person is often pressured by family and church members to return to the church, is reminded in many ways that they are to blame for their suffering and is readily condemned. In essence, they are forced to return to the perpetrator of their abuse.
