There are four main approaches to the post-cult recovery:
1. Purely psychological approach when the main goal is to address psychological and emotional problems caused by the cult involvement and a person's belief system is not affected.
2. Purely theological approach when the main goal is to change the person's belief system from incorrect (unorthodox, heretical) to correct (orthodox), but psychological and emotional issues are not properly addressed.
3. A combination of psychological and theological approaches that addresses both psychological and emotional problems and person's beliefs.
4. A combination of psychological and atheist approaches when psychological problems are addressed and a person is encouraged to leave religion completely.
I personally prefer approach that does not cause a person to change the belief system. I cannot agree with atheist/"ex-Christian"/"recovering fundamentalists" approach because of their atheist propaganda. They claim that any religion is abusive and promote leaving it completely. Ironically, their arguments very much repeat arguments used by communists. Communists also taught that any religion is abusive and promoted atheism. Was communist atheism less abusive? Of course, not. Atheism as well as religion may be very abusive.
The problem with theological approaches is the definition what is the correct and incorrect religion. In Russia, there are rehabilitation centers that have a goal of conversion ex-members of cults to Russian Orthodox church. Thus, they consider that a person is recovered if he or she joined Russian Orthodox church. There are evangelicals (in other countries) who believe that ex-cult members should be converted to evangelicalism and who consider that a person is recovered only if he or she was converted to evangelicalism. Who of them is right? It is hard to tell.
There is a difference between post-cult recovery and religious (or atheist) propaganda. I do not think that these things should be mixed. I do not think it is ethical to promote any religion or atheism to ex-cult members (especially newly exited) because of their vulnerability. So, I am against it.
On the other hand, ex-members of cults may have theological questions and issues. I think that in this case they may be benefited from theological counseling if the counselor does not promote his/her belief system and does not seek to change the ex-cult member's belief system.
