It definitely sounds like you've really thought this out and have made a good decision. Especially if you want to counsel people while having a religious aspect to it. I think that would add a great dimension to a therapy experience. Spirituality definitely deserves a place in psychology.

However, I went to a state school and I had a really great experience with the religious studies department. They were very accepting of various views. So, it's still possible to have religion enter into the equation at a state school.

FYI - Not to spark controversy but my anthropology class was basically hijacked by two fundamentalist Christians who basically stopped the class from learning what we'd paid to sign up for. So, people are rude on both ends of the spectrum.
