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]
