I have only anecdotes so no. And I don't know if there is actually a real way to find out. But I think therapy itself is fundamentally secular. I think Freud used to see God as a father figure type illusion. How could a therapist or analyst recommend going to church or go to church himself/herself, when one is trained to view religious orientation in these terms? It's like how homosexuality used to be viewed as a mental illness. It depends on your frame of thought.

I think psychological way of looking at life is in direct rivalry with religious views. A therapist who also happens to be religious is likely not seen as "scientific minded" by colleagues. Because psychology "reduces" essentially all religious feelings and beliefs to psychological phenomenon. The only way I can imagine a therapist taking part in religious practices would be either the person living a double life or the person focusing on some other aspect of the religious practice (e.g. going to church to see old friends and enjoy social interactions, not actually believing in anything said or done over there).
