Orthodox psychotherapy refers to "the process of spiritual growth and development" as used in the Eastern Orthodox Church.[1] In this context, it is a theological term rather than medical or psychological term.[2] The term is not limited to traditional psychotherapy used to treat psychological problems, but it rather refers to all people by dealing with their core existential issues.[3][4][5] Metropolitan Hierotheos introduced the phrase through his homonymous book.[1][6][7]
