Yeah it seems kind of weird.
Having said that, whatever belief system a therapist has shouldn't impact on their ability to give therapy. Check out their qualifications. Meet them and see if you feel comfortable with them as this is the basis of good communication and good therapy.
I have a few differences of opinion with my T but its no big deal. He is a competent, caring and capable person. We accept each other.
So go and chat, like you would with any T and decide from there.
Hope it goes well.
