Specifically what kind of “training” does a marriage therapist receive, that makes him any more qualified to offer marriage therapy?
The answer is he receives training in goyishe ideas and philosophies as to how a marriage should work.
Bad idea.
And if you are to claim that frum marriage therapists are different, my question is how are frum therapists trained differently than goyishe therapists?
Answer: They are not trained any differently.
